Abstract:

This project studies one of the most intense moments of the judicialization of Mexican politics: the Mexican Supreme Court of Justice’s intervention in the legal reforms on abortion and same sex marriage approved by the Legislative Assembly in Mexico City in 2007 and 2009. The cases stimulated the optimism of a transnational sexual rights agenda with images of progressive legal reforms and a responsive Court. But a study of the cases, it is argued here, reflects little engagement of the Supreme Court with human rights agendas of progressive images of judicial activism; instead, the momentum of judicialization speaks of a critical period of readjustment of authority in Mexico’s democratic institutions. Judicialization in Latin America is generally studied as the opening of constitutional courts to the citizenry and the establishment of tools for judicial review as the guarantor of constitutional rights in the new democracies. The Mexican experience of judicialization has been of a Court becoming the arbiter of conflicts between the executive and legislative branches of the government; it was historically initiated as a project to guarantee the stability of the political regime and the federal order. The Mexican Supreme Court evolved in democracy with a narrow formalist and self-constrained interpretation of human rights. The sexual rights cases were accepted by the Court when it was going through a compromising political period, and their successful decisions helped to moderate the legitimacy of the judicial tribunal, encouraging the attachment of social movements towards the Court, seen as a vehicle for social change. The thesis recognises sexual rights as a location of enunciation and production of subversive knowledge, generating intimate processes of subjective empowerment that inform new relationalities across a political sphere which includes legal culture. Sexual rights guide the study of the Court and the desire of a better trajectory of judicialization. The legal reforms and their judicial interventions are presented as optimistic promises, as signs that anticipated something good to come, even though they did not fully deliver against such hopes. Part 1 presents a theoretical frame to engage with optimism and promises, aiming to relate to the strategies of critical optimism with which one as a researcher can evaluate the conditions in which different people can relate (or not) to desired futures. Chapter 1 is a theoretical consideration of promises and optimism, chapter 2 presents the optimistic development in the new constitutionalism in Latin America embodied in constitutional moments, or constitutional reforms. Part II presents the political context that precedes the cases: first, in chapter 3, with the history of Mexico City and the institutionalisation of opposition, and then, in chapter 4, with the establishment of tools for constitutional review in the Supreme Court. Part II is dedicated to the case studies.

Abstract:

This dissertation is a feminist ethnography about on-street sex work and transgender politics in contemporary Mexico. It focuses on the socioeconomic and symbolic tensions existing between trans activists and trans vendors, mostly of sexual services, in Mexico City. It is based on ethnographic research consisting of participant-observation, formal interviews, informal conversations, and travel companionships with low-income female-gendered transpeople and self-identified trans activists in places of work, homes, social gatherings, and activist events about sexual diversity. The fieldwork for this study was conducted between 2010 and 2011, with shorter research periods spanning 2009 to 2014. The research also draws on bill proposals and official stenographic transcripts of socio-legal discussions held in Mexico City’s Legislative Assembly between 2001 and 2013. This study shows that, while not all transpeople are sex workers, a sizeable number of low-income trans women work as sexual labourers on the streets of Mexico City. Trans women have gained increasing visibility in on-street sex trade areas. Impoverished transpeople suffer the symbolic and material expressions of a generalized disrespect and disregard affecting on-street sex workers and low-income female-gendered transpeople. A sexual labour framework is thus critical to understand the ways in which social class and informal on-street vending shape the circumstances, livelihoods, and aspirations of low-income trans women. Their daily realities are shaped but not subsumed or exhausted by gender expressions and subjectivities or sex–gender systems alone. A class and labour lens, in addition to a gender lens, is necessary to shed light on the often-overlooked dimensions of socioeconomic standing and employment background that frame the lives of trans activists and trans sex workers. This project applies an intersecting critical trans and sexual labour analysis to understand the socioeconomic concerns and livelihoods of female-gendered transpeople. It contributes to the ethnographies of Mexico by underscoring regional and class diversity in the experiences and circumstances facing Mexicans. Lastly, this work helps refine feminist anthropology by demonstrating the utility of classic concepts to understand shifting intersecting realities and, more broadly, by refusing to conflate trans and sex work issues in Mexico with those found in other contexts.

Abstract:

The most speciose group of fishes in the Gulf of Mexico is the dragonfishes (Family: Stomiidae). These fishes are dominant mesopelagic predators occurring throughout the world’s oceans, including the Antarctic seas. Little is known regarding their reproductive ecology, a consequence attributed to insufficient sample sizes of mature adults due to inadequacies of sampling gear; larger, sexually mature stomiid adults are more adept at net avoidance, thereby obfuscating synoptic reproductive biology studies. Between 2010-2011, the Offshore Nekton Sampling and Analysis Program was initiated in the northern Gulf of Mexico over all four seasons using a discrete-depth sampling system (MOCNESS) and a large, commercial-sized midwater trawl (Irish herring trawl). Gonads were dissected from 714 individuals belonging to 47 species of stomiids, of which the most 12 abundant species were subjected to detailed analysis. Female ovaries possessed an asynchronous oocyte development, suggesting that females are iteroparous. Males exhibited a similar pattern. Chauliodus sloani had an overall sex ratio that favored females, and was the only species in which the overall sex ratio significantly differed from the expected 1:1 ratio (male:female) (P < 0.05). Considering just mature specimens, Aristostomias xenostoma, Malacosteus niger, Eustomias fissibarbis, and Eustomias schmidti had sex ratios that favored males, and were the only species in which the sex ratio significantly differed from even (P < 0.05). Eustomias hypopsilus was the only species in which mean biomass significantly differed between sexes. Histological analysis and binomial regression indicated that females of the 12 most abundant species matured at larger lengths than males. Generally, only females were present in the larger size classes, suggesting that females also become larger than males. Size distribution plots by gear type to assess gear selectivity revealed two patterns: the MOCNESS caught fewer specimens per species than the Irish herring trawl, and the MOCNESS caught predominantly smaller specimens. These data are essential for ecosystem-based modeling of global deep-pelagic ecosystems, which contain the overwhelming majority of Earth’s fish biomass.

Full text

Abstract:

I examine some of the ecological and evolutionary implications of body size in hermit crabs, with special emphasis on the upper intertidal species Clibanarius digueti. In Chapter 1 I show that body size had a far greater effect than species identity on desiccation tolerance for shell-less individuals of C. digueti, Paguristes anahuacus, Pagurus lepidus, and Phimochirus roseus. In contrast with other intertidal taxa, there was no correlation between the upper tidal limit of a species and the expected desiccation tolerance of an average-sized, shell-less individual of that species. This suggests that the gastropod shell that normally houses the hermit crab is sufficient to eliminate desiccation as a community-structuring force in this guild. Clibanarius digueti exhibits strong sexual dimorphism in body size, with almost no overlap in size between adult males and females. In Chapter 2 I show that sexual differences in the intensity of selection on size favor this dimorphism. Specifically, male mating success depended more strongly on body size than did female fecundity. In fact, the rate of increase in fecundity with body size equalled the lowest previously recorded for decapod crustaceans, suggesting that sexual size dimorphism in this species may depend more on weak fecundity selection on females than on strong sexual selection on males. Documenting contemporary selection on a character, however, is not the same as documenting that selection caused the character to evolve. Chapter 3 presents the first empirical test in a single species (C. digueti) of the hypothesis that sexual size dimorphism represents an evolutionary response to sexual differences in selection on size. The test is based on a general model that predicts crab body size as a function of shell limitations, shell fit and body size. Both males and females occupied optimally sized shells of non-preferred species, but the greater the desirability of a shell species, the greater the tendency for males to occupy tighter-fitting shells than females. Males also apparently suffere higher mortality than similarly-sized females. According to the general model, these results agree with the hypothesis that differential selection is causally involved in the evolution of sexual size dimorphism, and contradict the alternative hypothesis that energetic constraints on females produce the dimorphism.

Abstract:

DIE LEGALISIERUNG DER INTIMITÄT IN MEXIKO von Manuel Castillo Diese Dissertation wurde zur Erlangung des akademischen Grades Doctor iuris (Dr. iur.) an der Juristischen Fakultät der Humboldt-Universität zu Berlin in Deutschland vorgelegt. Das Hauptthema der Forschung ist die Legalisierung der Intimität, am Fallbeispiel des mexikanischen Rechts. Mit der Prämisse, dass das Recht auf Intimität sich aus dem Recht auf Privatsphäre ergibt, bespricht diese Forschungsarbeit die grundlegenden Menschenrechte, die einen Rahmen für die Legalisierung der Intimität ermöglichen. Die Einführung, der Sphären und Strukturen der Intimität, liefert eine Vorgehensweise zur Analyse dieses Themas. Es erfolgt eine Betrachtung der Frage der Geschlechter in ihrer Beziehung mit dem Recht und der Intimität. Aus einer „queer“ Perspektive hinterfragt diese Dissertation die Gleichstellung von Ehe und gleichgeschlechtlicher Ehe, mit dem Argument, ob eine neue Form der Legalisierung der Intimität für alle notwendig ist. Darüber hinaus, liefert diese Arbeit eine vergleichende Bewertung der mexikanischen Rechtsvorschriften im Rahmen des Völkerrechts. Am Ende der Dissertation, wird ein Vorschlag zur Legalisierung der Intimität im einundzwanzigsten Jahrhundert dargeboten.
THE LEGALIZATION OF INTIMACY IN MEXICO by Manuel Castillo This dissertation has been submitted in partial fulfillment of the requirements for the degree of Doctor iuris (Dr. iur.) at the Faculty of Law, of the Humboldt-Universität zu Berlin in Germany. The main scope of the research is the legalization of intimacy, using Mexican law as a case study. Considering that the right to intimacy arises from the right to privacy, this research discusses the fundamental human rights that constitute a framework for the legalization of intimacy. The research provides an approach to the analysis of this subject that includes what has been introduced as the Spheres of Intimacy and the Structures of Intimacy. The issue of gender is discussed in its relationship with the law and intimacy. From a queer perspective, this dissertation questions the equality of marriage and same-sex marriage, arguing that a new form of legalization of intimacy for all is needed. Furthermore, this study provides a comparative review of Mexican legislations within the framework of international law. At the end, this dissertation offers a proposal for the legalization of intimacy in the twenty-first century.

Abstract:

This dissertation examines the influence of love and other emotions on sexual and drug-related HIV risk among female sex workers who inject drugs and their intimate, non-commercial partners in Tijuana, Mexico. My work on a public health study along the Mexico-U.S. border and independent ethnographic research in Tijuana suggests the importance of emotions in shaping sex workers' relationships and health risks. Love is a universal human emotional experience embodied within broader cultural, social, and economic contexts. A growing body of cross-cultural research suggests that modern relationships have transformed to emphasize love and emotional intimacy over moral or kinship obligations. Particularly in contexts of risk and uncertainty, intimate relationships provide emotional security. Drug-using couples may engage in unprotected sex or even needle sharing to convey notions of love and trust and help sustain emotional unity, but such acts also place partners at heightened risk for HIV. For female sex workers in Tijuana who endure poverty, marginality, and an increased risk of contracting HIV, establishing and maintaining emotional bonds with intimate partners may be of paramount importance. Yet little is known about how female sex workers' intimate male partners shape their HIV risk perceptions and practices. Moreover, male partners' perspectives are critically absent in HIV prevention strategies. This dissertation is nested within Proyecto Parejas, a study of the social context and epidemiology of HIV among sex workers and their non-commercial male partners in Tijuana and Ciudad Juarez, Mexico. Through semi-structured and ethnographic interviews, photo elicitation interviews, and participant observation, I got to know seven of the couples in Tijuana who are enrolled in Parejas. I examine their relationships through the lens of critical phenomenology, which combines concern with experience, emotions, and subjectivity with political economy perspectives that argue sex work, drug use, and HIV/AIDS is not randomly distributed but historically and structurally produced. My work suggests that female sex workers and their intimate partners experience their relationships in gradations of love and emotional content. These relationships hold significant meaning in both partners' lives for emotional and material reasons, and shape each partner's HIV risk within and outside of the relationships. Couples choose not to use condoms with each other, often to define themselves as a couple. Sex outside of the relationship occurs for economic and culturally conditioned reasons, but does not necessarily diminish the meaning of the primary relationship. Motivations and ability to use condoms with clients and outside partners are context dependent and, in order to preserve trust and unity, sexual risks are typically not discussed. Partners share drugs and syringes with each other as a sign of care within a context of scarce material resources. Emotionally close couples tend to confine their sharing within the relationship, whereas less close couples also share with friends and family in more social forms of drug use. Given their vulnerability within a milieu of poverty, social marginalization, and discrimination, love alone cannot explain the HIV risk that female sex workers and their partners face. Nevertheless, emotions are significant factors in both risk taking and risk management. This study encourages researchers, practitioners, and policy makers to consider the affective dimensions of HIV risk within sex workers' intimate relationships as an integral part of a multi-level strategy to address each partner's health and wellbeing.

Pre-exposure prophylaxis (PrEP) has limited availability across Latin America, though access is increasing. We explored PrEP uptake in Mexico via an online survey completed by Spanish-speaking, Hornet geosocial networking application (GSN app) users without HIV (n = 2020). Most (81.3%) had heard of PrEP, 3.5% were current users, and 34.2% intended to take PrEP within six months. Current PrEP use was associated with PrEP eligibility (aOR 26.07 [95%CI 13.05–52.09], p < 0.001), recent STI testing (aOR 3.79 [95%CI 1.10–13.11], p = 0.035), and recent chemsex (aOR 3.02 [95%CI 1.02–8.93], p = 0.046). Recent STI testing was associated with hearing about PrEP from a doctor (aOR 3.26 [95%CI 1.98–5.36], p < 0.001), and those who lived in large cities were less likely to have learned about PrEP via Hornet (aOR 0.52 [95%CI 0.32–0.85], p = 0.009). Interventions to increase PrEP uptake in Mexico should build upon existing health networks and utilize GSN apps for PrEP information dissemination, particularly in less populated areas.

The present study aims to conduct a historiographical examination of the book El Perfil del Hombre y la Cultura en México from Samuel Ramos, dated 1934. Accordingly, we seek to amalgamate the importance of intellectual to understand the culture and being mexican, from the reading that another Latin American’s intellectuals have made from this book, looking for similarities and differences in their considerations. Therefore, we performed this exam from themes that Samuel Ramos verticalizes in his book, the main ones being the "feeling of inferiority," the "unthinking imitation" and "creole culture".

This dissertation examines some elements of the complex spatiality in Pedro Páramo, verifying how these elements stablishes associations to the focus and structure of the only novel written by the Mexican writer Juan Rulfo. Our research is based on the correlation between space and focus and how the space is related to the structure of the text. We take into consideration the critical aproaches presented by Luis A. Brandão, Ozíris B. Filho among others who have studies based on topoanalysis. The story is told from the perspective of multiple narrators who have died, changing the settings of time and space that rules the novel, making it very atypical. These characteristics are strongly linked to the peculiar structure of the narrative and the behavior of the characters and narrators who offers a post mortem angle of their stories. Due to the breaking of barriers separating life and death, the characters move through several layers of time and space, doomed to pay his penalties indefinitely on Comala, the ghost town where the story is set.
Propomos, nesta dissertação, a análise de alguns dos elementos que compõem a complexa espacialidade presente em Pedro Páramo, verificando como esses elementos espaciais se relacionam com a focalização e a estruturação da narrativa do único romance do escritor mexicano Juan Rulfo. Nossa pesquisa contempla as relações entre espaço e focalização que está compreendida no terceiro modo da abordagem proposta por Luis A. Brandão, além de aspectos do segundo modo que relaciona o espaço e a estruturação do texto. Também estão contempladas as considerações críticas apontadas por Ozíris B. Filho sobre o espaço da narração e o espaço da narrativa. Por ser uma história contada sob a perspectiva de múltiplos narradores que já morreram, as configurações de tempo e espaço que regem o romance assumem características absolutamente atípicas. Tais características estão fortemente ligadas à peculiar estruturação da narrativa e ao comportamento das personagens e narradores que oferecem um ângulo post mortem de suas histórias. Devido ao rompimento das barreiras que separam vida e morte, as personagens se movimentam por diversas camadas de tempo e espaço, fadadas a se repetir ao pagar suas penas e reiterar a morte indefinidamente por Comala, cidade fantasma onde a narrativa está situada.

A model was created to form synthetic plots of sea surface height (SSH) from monthly SSH statistics in the Gulf of Mexico generated from satellite laser altimetry data. SSH is a signal of the upper ocean mixed layer heat content and is an input for hurricane intensity models. A significant ocean feature in the Gulf of Mexico is the Loop Current (LC) which sheds warm eddies into the Gulf of Mexico at irregular intervals, which adds to the variability in monthly SSH readings beyond seasonal change. Satellite laser altimetry data was used from October 14th 1992 to May 23rd 2007. The SSH data included an area of the Gulf of Mexico (16°N-30°N latitude, 80°W-100°W longitude) with a resolution of 1/3° by 1/3° on a Mercator grid. Monthly SSH averages, variances, and covariances were created from a total of 763 samples, which allowed for approximately 65 samples per month. Once monthly SSH averages, variances, and covariances were made, synthetic plots were made by using a Karhunen-Loève transform, the Singular Variable Decomposition of the SSH monthly covariance, and random vector composed of random numbers in a Gaussian distribution. Differences in synthetic SSH plots compared to individual SSH observations could vary greatly; the average of all synthetic SSH plot nodes differed by no more than plus or minus 10 cm. The difference between observed and synthetic SSH variance was no more than 400 cm². The large differences occurred in the in the eddy shedding region of the LC. To assess the effectiveness of the model, the synthetic SSH model will need to be used in a hurricane intensity model.

Abstract:

I studied the in-water anthropogenic impacts on sea turtles, origins of sea turtles on foraging and developmental areas, their migration routes, and described regionally appropriate conservation needs. Sea turtles inhabiting Baja California waters originate on distant beaches in Japan, Hawaii, and southern Mexico. Results from genetic analyses, flipper tagging and satellite telemetry indicate loggerhead turtles (Caretta caretta) feeding along Baja California's coast are born in Japan and make a transpacific developmental migration of more than 20,000 km, encompassing the entire North Pacific Ocean and that East Pacific green turtles (Chelonia mydas) originate on and return to rookeries in Michoacan, and the Islas Revillagigedo, Mexico. Hawksbill turtles (Eretmochelys imbricata), once the target of a lucrative fishery for their shell, are now extremely scarce and only juveniles were encountered. The region's importance to the biology of sea turtles, regionally and Pacific-wide, warrants urgent conservation action. While protected legally, sea turtles are subject to furtive hunting and incidental catch. Coastal development, pollution, and boat collision are secondary threats. Annual consumption of sea turtles in the region is estimated at between 7,800 and 30,000 animals. Sea turtles are eaten regularly in most coastal communities and turtles are considered an irreplaceable traditional food. The decline of sea turtles in these waters has cost us both ecologically and culturally. Sea turtle recovery in Baja California, as all conservation activities, will be a matter of cultural and social evolution. For recovery to occur, strong, community-based incentives and educational programs are needed. In the near term, increased enforcement efforts, monitoring of mortality, and establishment of sea turtle sanctuaries are among the solutions. Without expansion to include community-specific initiatives such efforts may be futile. A long-term, multi-faceted sea turtle "conservation mosaic" program has been launched, consisting of community-based research on life history and population biology, an international education and public outreach campaign, regional sea turtle conservation areas, a monitoring and stranding network, and several policy initiatives that will permanently protect sea turtles and their habitat.

Peate, Ailsa Miriam. "Subversive sex, gender, and genre in Cuban and Mexican detective fiction." Thesis, University of Liverpool, 2017. http://livrepository.liverpool.ac.uk/3009104/.

Full text

Abstract:

This thesis engages with the concepts of sex, gender, and genre in relation to detective fiction produced in Cuba and Mexico. In order to do so, it focuses on a total of 4 novels from two Cuban authors and 5 novels from Mexican writers as case studies to question and consider the extent to which cultural production from each country should be considered original in its own right. After considering both countries' socio-political backgrounds and their attitudes towards gender roles, this research suggests that Cuban detective fiction from a post-Soviet era demonstrates preoccupations with neoliberal policy and its effect on sexuality on the island, and that Mexican detective fiction seeks to foreground women's issues in a country affected by gender violence, however on occasion this intention is undercut by the limiting and limited female characters available, fuelling systemic violence. Given the focus of specific cultural realities for both societies, this thesis concludes that Cuban and Mexican detective fiction are original generic subversions, and should be considered more closely in their own right. This thesis moves beyond academic scholarship previously found in the field due to not only its focus on gendered and sexual identities within examples of Latin American detective fiction, but also as it considers the way in which such representations distort accepted archetypal norms of detective fiction. Furthermore, it coins the phrase 'detective metafiction' to refer to particularly self-aware detective fiction which incorporates historical event and fact, leading the reader to question the very basis of such novels, a highly unusual trait within a genre typically associated with truth and revelation. This research contends that the four authors whose work forms the primary texts of this thesis demonstrate clear breaks with literary and social norms in their representation of gender, sex, and genre. Chapters One and Two consider the work of Cuban authors Leonardo Padura and Amir Valle after the fall of the Soviet Union respectively, and Chapters Three and Four engage with the work of Bef and Rogelio Guedea, both whom have produced detective fiction since the inception of the War on Drugs.

Abstract:

This study develops a theoretical framework to examine the major dimensions of transformational leadership style (TLS), public service motivation (PSM), organizational citizenship behavior (OCB), and public organization performance (POP). It is hypothesized that when employees perceived a public organization is practicing a transformational leadership style, they are likely to have a favorable view on the performance of their organization, but the effect is indirect and mediated by OCB. At the same time, if employees have a strong desire to serve and improve the welfare of others, they are likely to perform beyond their job requirements and thus, likely to express a positive view on the organizational performance. A structural equation modeling was used to examine 1,016 public employees (67.7% response rate) in the Guadalajara metropolitan area, Mexico i.e., concerning their perceptions about leadership style, motivation to serve in the public sector, citizenship behaviors, and public organizational performance. The results suggest that if Mexican public employees perceived their leaders to adopt a transformational leadership style, they were likely to have a favorable view on the performance of their organization (direct effect); and that, the effect is mediated by their tendency to engage in activities that would contribute to the functioning of the organization without expecting any kinds of reward (indirect effect). In addition, if employees have a strong motivation to serve in the public sector, they are also likely to have a favorable view on the performance of the organization; and that, the positive effect is mediated by their tendency to act for the goodness of other employees and organizations without expecting some form of reward (indirect effect). A multi-group analysis, based on the hypothesized model, revealed the associations varied across three groups: difference between male and female, places of employment within the public sector (i.e., local or state government), and job descriptions or major tasks performed by employees in an organization (i.e., services oriented or administrative role).

Abstract:

Density, species diversity, species richness, and evenness of bivalve mollusks were measured in the deep (0.2km to 3.7km) northern Gulf of Mexico to describe the community structure of benthic bivalve mollusks. Density decreased gradually from shallow continental slope depths, with remarkably high values in the Mississippi canyon, to the deepest sites. Diversity of bivalve mollusks increased from shallow continental slope depths, with low values in the Mississippi canyon, to a maximum at intermediate depths (1-2km), followed by a decrease down to the deepest locations (3.7km). Nine distinct groups were formed on the basis of the similarity in species composition. The pattern varied more abruptly on the slope compared to the deeper depths, possibly due to steeper gradients in physical variables. ANOVA indicated that the density of bivalve mollusks was not significantly different at different depths, was not significantly different on different transects, was not significantly different between basin and non-basin, but was significantly different in canyon and non-canyon locations. Similar distinctions were observed in diversity, except that basins were lower than non-basins. The patterns observed reflect the intense elevated input of terrigenous sediments accompanied by high surface-water plankton production from the Mississippi River to the north central gulf.

Abstract:

Continuous or semi-continuous reproduction is the norm in deep-sea animals, with exceptions explained by seasonal pulses of surface-derived phytodetritus. Chemosynthesis-based ecosystems such as cold seeps have an independent nutritional supply and are often thought of as decoupled from surface productivity. This thesis explores reproductive patterns of four bathymodiolin mussel species from 14 cold seeps (320 to 3300 m depth) in the Gulf of Mexico (2014) and the northwestern Atlantic (2015). Using paraffin histology, I determined maturity stages for male and oocyte sizes for female mussels. All species at all sites reproduced periodically and synchronously, with geographic synchrony among sites. This suggests that mussels rely on a site-independent cue such as seasonal phytodetrital flux to synchronize reproduction, providing evidence for a stronger coupling between surface productivity and chemosynthesis-based fauna than previously expected. Mature oocytes were of similar size for all species at all depths, suggesting that egg size is phylogenetically constrained.

Abstract:

Cette thèse examine l’alternance en romani du Mexique de la copule si et des clitiques sujet -lo ; -li/-la ; -le. Il s’agit d’un phénomène linguistique absent de toutes les variétés romani parlées en Europe et qui selon Adamou (2013) s’est développé sous l’influence de l’espagnol dans les communautés romani installées en Amérique Latine depuis le 19e siècle. La présente étude s’appuie des données originales collectées auprès de locuteurs bilingues de la communauté de La Rinconada dans l’État de Veracruz au Mexique. En analysant un corpus oral spontané d’environ 16 heures et les réponses de 60 personnes à un questionnaire de choix de copule, j’ai pu dégager les variables qui sous-tendent l’emploi des copules en espagnol et romani. Les variables linguistiques décrites traditionnellement pour la variation des copules ser et estar en espagnol, comme par exemple le Cadre de référence et le Type de prédicat, s’avèrent aussi pertinentes pour comprendre l’emploi des copules romani. Les clitiques sujet romani sont particulièrement dynamiques dans les constructions de troisième personne affirmatives au présent où ils tendent à éclipser la copule romani traditionnelle si. Il est possible d’argumenter que cette expansion provoquée par le contact avec l’espagnol influence à son tour l’emploi des copules en espagnol. En effet, on observe parallèlement un dynamisme de la copule estar et son extension à des contextes précédemment occupés par la copule ser, une tendance plus générale documentée par ailleurs pour l’espagnol du Mexique
This thesis examines the alternation in of the Romani copula si and the subject clitics lo; -li/-la; -le. It is a linguistic phenomenon that is absent from all the Romani varieties spoken in Europe and which according to Adamou (2013) has been developed under the influence of Spanish in the Romani communities who have settled in Latin America since the 19th century. This study has been possible thanks to the collection of original data from bilingual speakers of the community of La Rinconada in the State of Veracruz in Mexico. Based on the analysis of a spontaneous oral corpus of approximately 16 hours and responses from 60 participants to a questionnaire of copula choice, I was able to identify the variables underlying the use of copulas in both languages. The linguistic variables described for the variation of the copulas ser and estar in Spanish, as for example the frame of reference and the type of predicate, are also relevant to understand the use of copulas in Romani. However, it appears clearly that the Romani subject clitics are particularly dynamic in present affirmative constructions of third person where they tend to overshadow the traditional Romani copula si. It is possible to argue that this expansion that started under the influence of Spanish is now in turn influencing the use of Spanish copulas. Indeed, there is in parallel a dynamic use of the copula estar and extension to contexts previously covered by the copula ser, following a more general trend documented in Mexican Spanish

Abstract:

Biology
Ph.D.
Cold-water corals are an important component of deep-sea ecosystems as they establish structurally complex habitats that support benthic biodiversity. These communities face imminent threats from increasing anthropogenic influences in the deep sea. Following the 2010 Deepwater Horizon blowout, several spill-impacted coral communities were discovered in the deep Gulf of Mexico, and subsequent mesophotic regions, although the exact source and extent of this impact is still under investigation, as is the recovery potential of these organisms. At a minimum, impacted octocorals were exposed to flocculant material containing oil and dispersant components, and were visibly stressed. Here the impacts of oil and dispersant exposure are assessed for the octocoral genus Paramuricea. A de novo reference assembly was created to perform gene expression analyses from high-throughput sequencing data. Robust assessments of these data for P. biscaya colonies revealed the underlying expression-level effects resulting from in situ floc exposure. Short-term toxicity studies, exposing the cold-water octocorals Paramuricea type B3 and Callogorgia delta to various fractions and concentrations of oil, dispersant and oil/dispersant mixtures, were also conducted to determine overall toxicity and tease apart the various components of the synergistic exposure effects. Finally, alterations in Paramuricea B3 gene expression profiles were inspected to characterize genome-wide changes induced by each treatment and putative genes under differential regulation. The experimental results provide evidence for a relatively high toxicity of chemical dispersants as compared to oil additions alone, elucidating the implications of applying oil dispersants to future oil spills. My findings revealed signatures of cellular stress in floc-exposed corals associated with xenobiotic metabolism, immune and inflammatory responses as well as transcriptional suppression of vital cellular components like ribosomal proteins. The data also suggests poor recovery potential in our coral samples exposed to floc. In addition, promising biomarker candidates were identified from the differential expression data for use in future spill-impact monitoring.

Abstract:

The central research question of this exploratory study is to determine if college educated, ethnically identified and preferred endogamous Chicanas experience significantly more psychological distress due to a conflict between their educational achievements and beliefs that Chicano males are threatened by high achieving women. The specific perceptions are: that Mexican American males feel threatened by their educational accomplishments, tend to exclude them from political and organizational activities, and that college attainment will cause them to be seen as elitist by the larger Chicano community. This study uses descriptive and correlational analysis to explore the relationship between ethnic identification, preferred endogamy and perceptions that Chicanas high achievements pose a threat to Chicano males as predictive factors for higher psychological distress. The sample consists of 508 randomly selected Chicanas at five colleges, varying in selectivity from a private university to a community college. The majority of respondents are single and under thirty. A sample of 160 Chicano males were also randomly selected from three of the same five college campuses and were used to make comparisons on the threat dimension. The instrument is a mail questionnaire.

Abstract:

Macrobenthos of the deep, northern Gulf of Mexico have been sampled with large box cores along multiple cross-depth transects extending from depths of 200 m out to 3700 m. Four major depth zones have been identified based on the faunal similarities (beta diversity) between geographic sites, with the two intermediate-depth zones being divided horizontally down the middle of the basin. The input of food resources appears to control the observed patterns. Each zone and sub-zone can be described by a characteristic animal density, biomass and biodiversity (alpha diversity). Highest densities and biomass occurred in two large submarine canyons, the Mississippi and De Soto Canyon, but the two habitats are markedly different. The alpha diversity displays an intermediate depth maximum. Species richness (gamma diversity) is highest on east mid-slope, due, we suggest, to habitat complexity, but alpha diversity is lowest at the canyon head due to extreme dominance by amphipods. Small mean individual size and low densities encountered are a reflection of the meager surface water primary production, albeit with exceptional isolated habitats in which detrital material is concentrated, such as canyons on the upper continental slope.

Doutoramento em Biologia
As tartarugas marinhas sofrem um forte impacto populacional devido às atividades antropogênicas, como as causadas pelo aumento da exploração comercial e industrial nas áreas costeiras, alteração do habitat, ingestão de resíduos sólidos, captura acidental nas atividades pesqueiras e a contaminação de poluentes químicos. Das sete espécies de tartarugas marinhas existentes distribuídas por quase todos os oceanos (Caretta caretta, Chelonia mydas, Dermochelys coriacea, Eretmochelys imbricata, Lepidochelys olivacea, Natator depressus e Lepidochelys kempii), exceto o Natator depressus, todos os outros seis são listados como vulneráveis, em perigo ou criticamente ameaçado na lista da IUCN. Os contaminantes ambientais de origem química, como metais pesados, pesticidas, hidrocarbonetos, PCB, organoclorados e dioxinas estão causando um forte impacto na saúde de animais marinhos, incluindo tartarugas marinhas, e a bioacumulação desses poluentes em tecidos e órgãos influenciam o crescimento e desenvolvimento de populações naturais de tartarugas marinhas em todo o mundo, podendo causar mortalidade em vários estágios de seu desenvolvimento. Uma vez que estão em perigo é extremamente importante para a compreensão das respostas às medidas de impacto e conservação à longo prazo nas populações de tartarugas marinhas. Este trabalho é uma visão geral dos estudos sobre a quantificação de contaminantes em ovos e sangue de tartarugas marinhas, buscando relações entre o tamanho da carapaça e a atividade de enzimas antioxidantes usando técnicas não-letais. A concentração de pesticidas organoclorados (OCPs) no plasma das fêmeas adultas e os ovos das tartarugas de pente (Eretmochelys imbricata) e tartaruga verde (Chelonia mydas) que desovam na área costeira de Campeche serão analisados. O objetivo principal desta tese é avaliar o potencial das populações naturais como bioindicadores de contaminação química. Para tal, foram analisados os valores hematológicos, contaminação de OCPs no plasma e ovos de duas espécies de tartarugas marinhas com hábitos alimentares diferentes e uma possível transferência materna na espécie de tartaruga de pente. Por fim, a atividade de biomarcadores enzimáticos foram correlacionadas com a contaminação por OCPs. Os resultados mostraram que foram encontrados OCPs em todos os ovos analisados, mostrando maiores concentrações de ΣHCH e ΣDrines nas duas espécies selecionadas, sendo encontradas diferenças significativas entre as espécies e os anos analisados. Foram encontras diferenças significativas entre as concentrações de OCPs (ΣHCHs, ΣDrines e ΣChlordanes) em relação ao sangue e ovos, indicaram que esses contaminantes químicos estão sendo transferidos maternalmente. Nenhuma enzima antioxidante teve relação significativa com os OCPs mais encontrados no sangue (ΣDDTs, ΣHCHs e ΣDrines).
Sea turtles have been suffering strong population impact due to anthropogenic activities, such as those caused by the increase in commercial and industrial exploitation of coastal areas, habitat alteration, ingestion of solid waste, incidental capture in fishing activities and contamination of chemical pollutants. Of the seven species of marine turtles existing distributed by almost all oceans (Caretta caretta, Chelonia mydas, Dermochelys coriacea, Eretmochelys imbricata, Lepidochelys olivacea, Natator depressus and Lepidochelys kempii), except the Natator depressus, all other six are listed as vulnerable, endangered or critically endangered on the IUCN list. Environmental contaminants of chemical origin such as heavy metals, pesticides, hydrocarbons, PCBs, organochlorine, and dioxins are causing major health impacts of marine animals, including sea turtles, and bioaccumulation of these pollutants in tissues and organs influence the growth and development of natural populations of sea turtles worldwide, may cause mortality in various stages of development. Because they are endangered is extremely important to the understanding of responses to impact and conservation measures in the long term in the populations of sea turtles in developing. This work is an overview of studies on the quantification of contaminants in blood and sea turtle eggs, searching for relationships between, carapace size and the activity of antioxidant enzymes using non-lethal techniques. The concentration of organochlorine pesticides (OCPs) in plasma of adult females and eggs of hawksbill turtles (Eretmochelys imbricata) and green turtle (Chelonia mydas) that nest in the coastal area of Campeche will be analysed. The main objective of this thesis is to evaluate the potential of natural populations as bioindicators of chemical contamination. For this, the hematological values, contamination of OCPs in the plasma and eggs of two species of sea turtles with different feeding habits and a possible maternal transfer in the hawksbill turtles were analysed. Finally, the activity of enzymatic biomarkers was correlated with the contamination by OCPs. The results showed that OCPs were found in all analysed eggs, showing higher concentrations of ΣHCH and ΣDrines in the two species selected, being found significant differences between the species and the studied years. We find significant differences between the concentrations of OCPs (ΣHCHs, ΣDrines and ΣChlordanes) of blood to eggs showed that these chemical contaminants being transferred maternally. No antioxidant enzyme had significant relationship with COPs main found in the blood (ΣDDTs, ΣHCHs and ΣDrines).

This research takes place in a small middle school in Pescadero, Baja California Sur, Mexico. The research approach utilized in the study adds to the handful of studies in this cross-disciplinary field by employing quantitative methodologies to measure course outcomes on student environmental knowledge, perceptions, and actions, while simultaneously qualitatively describing the behavioral, educational, environmental, and social experiences of students. This research employs Dewey's theories of experience -- as well as those of more contemporary authenticity theorists -- in order to identify the philosophies that advocate incorporating experiential pedagogy within the curriculum. Implications for Mexican educational policy, practical pedagogical applications, and theory are discussed.

Abstract:

Mexico was formerly an important breeding ground for six marine turtle species. Over the last several decades, overexploitation of turtles for their meat, eggs, and hides, as well as habitat destruction, has led to alarming rates of decline in all species. The problem of sea turtle conservation is a promising area for questions of anthropology and sustainable human systems because decline of these species is related to unsustainable development and subsistence practices that have disenfranchised small coastal fishing cooperatives. Common property resource theory aids the analysis of the context in which overexploitation takes place. Conserving sea turtles will depend on the development of localized institutions for managing natural resources in perpetuity and for negotiating the array of regional, national, and global factors relevant to sea turtle endangerment and preservation. Anthropology can play a vital role in this process of developing sustainable interactions between human subsistence needs and natural resource conservation.

Abstract:

The ecological forces that drive community structure of deep-sea benthic communities are poorly understood, yet such communities rival in biological complexity those of coral reefs or rainforests. Using components of the recently concluded DGoMB project, local and regional-scale structure of benthic macrofaunal communities were examined at thirty two locations throughout the continental slope of the northern Gulf of Mexico. Controlling factors associated with sediment disturbance, food supply, and faunal competition between functional ecological groups were evaluated for correlative and relational patterns. A higher order taxonomic sufficiency approach was used to calculate both alpha and beta diversity. The results of this study indicate that macrofaunal communities are very patchy, having wide variations in abundance at within-site, adjacent-site, and across-basin scales, yet all sample areas possess a large richness of higher taxa. Declining abundance was noted with increasing water depth and reduced particulate organic carbon levels. Upper-slope submarine canyons possess some of the highest abundances. Less mobile macrofauna, such as poriferans, bivalves, and scaphopods, dominate slope communities above the 500 meter contour. Sediments exhibiting intense megafaunal bioturbation inhibit abundances of sedentary macrofaunal taxa, but such mixing is positively associated with increased abundances of polychaetes and ambulatory crustaceans, including peracarids, harpacticoids, and ostracods. Prominent sediment mixing was noted at most sites, including portions of the Sigsbee Abyssal Plain. The western Gulf of Mexico was less biologically active than the eastern Gulf of Mexico, which possesses two extensive submarine canyons that appear to act as regional nutrient traps. I conclude that the physiographic complexity of the northern Gulf of Mexico continental slope influences macrofaunal community structure. Biological disturbance, in the form of sediment mixing, is widespread throughout most slope depths, and the benthic environment is food-limited. It appears that disequilibrium-type ecological processes predominate in this area, supporting similar findings by previous studies in other regions of the ocean, usually at far smaller scales and none representative at the basin-level. Use of higher order taxonomy in lieu of genus or species-level faunal identifications for diversity measurements was inadequate for detecting spatial patterns or environmental responses.

Abstract:

The ocean mixed layer response to a tropical cyclone within, and immediately adjacent to, the Gulf of Mexico Loop Current is examined using a combination of ocean profiles and a numerical model. A comprehensive set of temperature, salinity, and current profiles acquired from aircraft-deployed expendable probes is utilized to analyze the three-dimensional oceanic energy and circulation evolution in response to Hurricane Lili's (2002) passage. Mixed-layer temperature analyses show that the Loop Current cooled <1 degree C in response to the storm, in contrast to typically observed larger decreases of 3-5 degrees C. Correspondingly, vertical current shears, which are partly responsible for entrainment mixing, were found to be up to 50% weaker, on average, than observed in previous studies within the directly-forced region. The Loop Current, which separates the warmer, lighter Caribbean Subtropical water from the cooler, heavier Gulf Common water, was found to decrease in intensity by -0.18 plus/minus 0.25 m/s over an approximately 10-day period within the mixed layer. Contrary to previous tropical cyclone ocean response studies which have assumed approximately horizontally homogeneous ocean strucutre prior to storm passage, a kinetic energy loss of 5.8 plus/minus 6.3 kJ/m^2, or approximately -1 wind stress-scaled energy unit, was observed. Using near-surface currents derived from satellite alimetery data, the Loop Current is found to vary similarly in magnitude, suggesting storm-generated energy is rapidly removed by the pre-exiting Loop Current. Further examination of the energy response using an idealized numerical model reveal that due to: 1) favorable coupling between the wind stress and pre-existing current vectors; and 2) wind-driven currents flowing across the large horizontal pressure gradient; wind energy transfer to mixed-layer kinetic energy can be more efficient in these regimes as compared to the case of an initially horizontally homogeneous ocean. However, nearly all of this energy is removed by advection by 2 local inertial periods after storm passage, and little evidence of the storm's impact remains. Mixed-layer vorticity within the idealized current also shows a strong direct response, but little evidence of an near-inertial wave wake results.

Abstract:

In a world of growing interconnectivity, global scale social processes drive local-level change at ever-faster rates, shaping the challenges and opportunities faced by communities. Yet, literature on vulnerability and adaptation within social-ecological systems (SES) scholarship has largely centred on climate change and associated biophysical stressors. Key theoretical shortcomings are twofold. First, in SES scholarship, there has been limited engagement with non-climate anthropogenic drivers of change and characterization of how other social drivers impact communities and the larger social-ecological system in which communities are nested. Second, there has been less consideration of the differing timescales of change, resulting in a scholarship that is under-theorized in terms of how communities experience and respond to shocks (e.g., hurricanes, volatility in international markets, military coups) versus trends (e.g., rising ocean temperatures, urbanization). This thesis seeks to address these shortcomings by exploring the impacts of socially driven shocks in a coastal community, including implications for vulnerability and adaptation. Specifically, through a qualitative case study of a fishing community on Mexico’s Yucatán Peninsula, I investigate how a rapidly developed sea cucumber fishery, triggered by rising demand from international seafood markets, drives dramatic change in the social structure, functioning and feedbacks within the community. I demonstrate how the emergence of sea cucumber fishing has driven novel and rapid change in the community, introducing new stressors such as poaching and violent conflict, while exacerbating pressures from ongoing trends of population increase and overfishing of other commercially valuable species. Results suggest that this spike in pressure on the social system has impacted vulnerability and challenged the capacity of local institutions to respond adaptively. This includes a decreased capacity to manage local resources and increased risks to livelihoods for fishers. By attending to social drivers of rapid change in coastal SES, this research contributes to scholarship on multiple stressors and their contributions to local vulnerability. Finally, by focusing on the impacts of change on the structure, functions and feedbacks of social systems, I provide a framework that aligns with existing SES thinking and language while creating space for a more robust engagement with the social dimensions of these linked systems.

Abstract:

Evolution occurs and can be conceptualized along a spectrum, bounded on one extreme by the relationships between deep lineages – such as phyla, classes, and orders – and on the other by the molecular dynamics of operational taxonomic units within a species, defined as population genetics. The purpose of this dissertation was to better understand the evolutionary and population dynamics of crustaceans within the Gulf of Mexico. In the second chapter of my dissertation, I provide a guide to best phylogenetic practice while reviewing infraordinal relationships within Decapoda, including the promise held by next-generation sequencing (NGS) approaches such as Anchored Hybrid Enrichment. Chapter III is a phylogenetic study of species relationships within the economically important shrimp genus, Farfantepenaeus, targeting three mitochondrial genes and uncovering an intriguing pattern of latitudinal speciation. As the first inclusive molecular phylogeny of the genus, we find support for the newly described species F. isabelae, but a lack of support for the species status of F. notialis. Additionally, our results suggest the existence of two distinct subspecies of F. brasiliensis. Chapter IV investigates the relative impacts of habitat heterogeneity and the presence of a possible glacial refugium in determining population dynamics of the Giant Deep-Sea Isopod, Bathynomus giganteus in the northern Gulf of Mexico. Through hybrid population genetics/genomics analyses and Bayesian testing of population models, we find strong evidence for habitat heterogeneity determining population dynamics for this charismatic deep-sea invertebrate. Chapter V further investigates the role of environment in determining and maintaining genetic diversity and population connectivity, specifically focused on establishing biological baselines with which we can diagnose health and resilience of the Gulf of Mexico. This was accomplished through a comparative NGS population genomics study of three species of mesopelagic crustaceans: Acanthephyra purpurea, Systellaspis debilis, and Robustosergia robusta. While diversity and connectivity differs in each species, the comparative results bespeak the importance of access to the Gulf Loop Current in determining and maintaining population dynamics. Overall, my work significantly contributes to our knowledge of Crustacea at the phylogenetic- and population genetic-level.

Abstract:

Sediment core MD02-2550 from Orca Basin located in the northern Gulf of Mexico (GOM) provides a high-resolution early Holocene record of climatic and hydrologic changes from ~10.5 to 7 thousand calendar years before present (ka). Paired analyses of Mg/Ca and δ18O on the planktonic foraminifer Globigerinoides ruber (white variety, 250-355 μm) sampled at ~ 20 year resolution were used to generate proxy records of sea surface temperature (SST) and the δ18O of seawater in the GOM (δ18OGOM). The Mg/Ca-SST record contains an overall ~1.5 °C warming trend from 10.5 to 7 ka that appears to track the intensity of the annual insolation cycle and six temperature oscillations (0.5-2 °C), the frequency of which are consistent with those found in records of solar variability. The δ18OGOM record contains six ~ 0.5 ‰ oscillations from 10.5 to 7 ka that bear some resemblance to regional hydrologic records from Haiti and the Cariaco Basin, plus a -0.8 ‰ excursion that may be associated with the “8.2 ka event” recorded in Greenland air temperatures. The δ18OGOM record, if interpreted as a salinity proxy, suggest large salinity fluctuations (> 2 ‰) reflecting changes in evaporation-precipitation (E-P) and Mississippi River input to the GOM. Percent Globigerinoides sacculifer records from three cores in the GOM exhibit remarkably coherent changes, suggesting episodic centennial-scale incursions of Caribbean waters. Spectral analysis of the Mg/Ca-SST and the δ18OGOM time series indicate that surface water conditions may be influenced by solar variations because they share significant periods of variability with atmospheric Δ 14C near 700, 200, and 80-70 years. Our results add to the growing body of evidence that the sub-tropics were characterized by significant decadal to centennial-scale climatic and hydrologic variability during the early Holocene.

Abstract:

Mexico is home to almost 2.9 million square kilometers of land and water surface area that is affected by water pollution and environmental degradation. While geographically more prevalent to pollution threats as well as one of the most biodiverse countries in the world, it is important to coordinate the management and regulation of coastal zones effectively to safeguard these ecosystem from degradation. However, because of the UN Convention on the Law of the Sea, nations view the problem of living resources and their management as a national priority instead of an international cooperation initiative. Mexico's fragmented, overlapping, and sometimes corrupt domestic institutions for environmental policy yield ineffective and inadequate pollution control, a result of which is a high level of marine debris presence on the coasts, as evidenced by a recent study in Veracruz, Veracruz. This marine debris, the most abundant of which is composed of plastics, is detrimental to marine life, leading to death, starvation, debilitation, reduced quality of life and lowered reproductive performance. While several avenues are being explored to mitigate marine debris in the environment, such as decreasing knowledge gaps, increasing pollution prevention measures, and education, degradation issues have compounded globally, revealing a clear picture of inadequate international regulation and convention. A stricter Mexican national regulatory system that incorporates private and public waste management organizations to incentivize and facilitate waste cleanup is needed to improve the health of the global ocean.

Abstract:

The Canadian Regional Climate Model (CRCM) has been used to investigate the effects of Gulf of Mexico sea surface temperature (SST) anomalies on the regional climate. Three sets of experiments have been performed, each consisting of a control run and with two different imposed Gulf SST anomalies. The first is a uniform increase or decrease of the SST by 5K over the entire Gulf. The second and third experiments use 5K SST anomalies of smaller extent, characteristic of warm core rings shed off the Loop Current in the Gulf. The experiments are carried out for either 15 or 30 days, and statistics are computed after discarding the first 5 days of the integration.
The response of the SST anomalies are qualitatively similar in the three cases, except the response to the anomaly over the entire Gulf is stronger due to the much larger extent of the anomaly. For a positive SST anomaly, precipitation and moisture over the Gulf and southeastern U.S. both increase. The 1000mb temperature field shows a clear warming over the Gulf and adjacent areas, delineating the imposed SST anomaly. A low level cyclonic circulation forms over the Gulf and southeastern U.S. region, while an anticyclonic circulation develops at the upper levels. The negative SST anomaly experiments show a qualitatively similar response, except it is of opposite sign with a smaller magnitude.

Abstract:

Knowledge of species distribution and habitat associations are essential for conservation measures. Such information is lacking for many marine species due to their occupancy of broad and ephemeral habitats that are difficult to access for study. Sea turtles, specifically the surface−pelagic juvenile stage of some species, are a group for which significant knowledge gaps remain surrounding their distribution and habitat use. Recent research has confirmed the long−standing hypothesis that the surface−pelagic juvenile stage occurs within surface−pelagic drift communities (SPDC). Within the North Atlantic and surrounding basins, the holopelagic macroalgae Sargassum spp. dominates SPDC and serves as a remotely−detectable indicator of SPDC. The present study focuses on surface−pelagic habitats of four sea turtle species and addresses knowledge gaps using two approaches: habitat mapping and behavioral examination. Remote sensing techniques were used to identify SPDC, and satellite telemetry to examine behavior. This work was conducted in three parts and is presented in three chapters.

Imagery collected from the Landsat satellites (5 and 7) was used to quantify the area of SPDC (km²). Approximately 1,800 Landsat images collected from 2003–2011 were examined for SPDC. The first chapter discusses the abundance, seasonality, and distribution of SPDC within the eastern Gulf of Mexico waters where surface−pelagic green, hawksbill, Kemp’s ridley, and loggerhead turtles are known to occur. SPDC was found year−round within the eastern Gulf of Mexico, and the amount of habitat peaked during summer months. The amount of SPDC within the eastern Gulf of Mexico varied annually with peaks in 2005, 2009, and 2011. High concentrations of SPDC were discovered within offshore waters of the northeastern Gulf of Mexico and southern West Florida Shelf.

Within the second chapter, the behavior of 10 surface−pelagic juvenile Kemp’s ridleys was examined using satellite telemetry. Using remotely−sensed imagery, the sea surface habitats used by tracked turtles were examined. Surface−pelagic juveniles are hypothesized to be principally passive drifters. The behavior of tracked turtles was examined to determine if they exhibited periods of active and passive behavior, which may indicate periods of swim and drift. The proximity of tracked turtles to remotely−detected SPDC was examined when coincident Landsat imagery was available (within one day of the turtle’s position). Turtles were tracked for 36.5 days (mean) and exhibited primarily passive behavior during the tracking period. The satellite transmitters messaged frequently and reported temperatures significantly higher than sea surface temperatures. Landsat imagery was available coincident to the tracks of nine individuals. SPDC was present within 74% of images, and the mean distance between tracked turtles and SPDC was 54 km. Close associations between tracked turtles and SPDC were documented for four individuals. Results suggest that the tracked turtles spent a majority of the time drifting within SPDC.

The final chapter discusses the density of SPDC within northern and western Gulf of Mexico waters from 2009–2011. Seasonal abundance peaks occurred throughout the study area, but the timing varied. SPDC peaked earlier (late spring) within the northwestern Gulf of Mexico. Moving eastward, the timing of seasonal peaks shifted progressively later during the year. Within the western portions of the study area, SPDC was found to be significantly higher than in the eastern Gulf of Mexico.

The eastern Gulf of Mexico may provide critical developmental habitats for several North Atlantic sea turtle species. Additional study is necessary to determine if portions of the western Gulf of Mexico could serve in a similar capacity. SPDC is extremely vulnerable to anthropogenic impacts, specifically oil spills and the occurrence of persistent marine debris. Conservation of SPDC may be challenged by its ephemeral nature; however, the results presented herein could advise conservation efforts (e.g., delineation of critical habitat). The present study described spatial patterns of SPDC occurrence, regions of high abundance, and seasonality. The description of the behavior surface−pelagic sea turtles offers refinements to the spatial distribution of this life stage. These results, coupled with information on circulation patterns and the distribution of sea turtle nesting beaches, can be used to better predict when and where sea turtles and SPDC may be found. For example, the year−round persistence of SPDC within the eastern Gulf of Mexico and the location of major nesting beaches located upstream support the area’s designation as critical habitat for surface−pelagic green, hawksbill, Kemp’s ridley, and loggerhead turtles.

Abstract:

Nearly all deep-sea cephalopod life history studies have been completed by examination of specimens collected in the wild. Much of this work is like piecing together a puzzle; knowledge of the life history of many species remains fragmented and hence, taxonomically and phylogenetically confused. Molecular approaches and sequencing technologies are powerful tools for deciphering wild-type cephalopod life history and population dynamics. Use of molecular markers offers additional certainty for identifying specimens damaged during deep-sea collections and can elucidate often cryptic, intra- and interspecific diversity. The research presented in this study assessed broad genetic patterns of biodiversity in deep-sea cephalopods from the Gulf of Mexico and northwestern Atlantic Ocean. This study has two key objectives: [1] to examine intraspecies variation among regionally disjunct subpopulations, comparing collections separated by the Florida Peninsula, and [2] to examine intraspecies variation within deep-sea cephalopods in the Gulf of Mexico. Through Sanger sequencing marker genes COI, 16S rRNA, and 28S rRNA, this study has generated a genetic baseline characterization of deep-sea cephalopods in the Gulf of Mexico, assessed intraspecies genetic variation, and linked morphological identification with DNA barcodes, testing morphological hypotheses of species identification and naming. Results of investigating intraspecies variation within regionally disjunct subpopulations reveal there is no regional distinction between the Gulf of Mexico subpopulations of Vampyroteuthis infernalis, Pyroteuthis margaritifera, and Cranchia scabra, and the Bear Seamount subpopulations in the northwestern Atlantic Ocean. Results of investigating intraspecies variation within the Gulf of Mexico displayed potential for cryptic species, novel sequence records, and large expansions to sequence records for species known to inhabit the Gulf of Mexico. Analysis of intraspecies variation within the Gulf of Mexico facilitated identification of damaged specimens used for this study, but also revealed GenBank database issues of misidentified records, and outdated nomenclature in accession records. Because cephalopods play a central role in most oceanic ecosystems, characteristics like a short average life span and a rapid growth rate mean that cephalopod populations have the potential to serve as an invaluable reflection of ecosystem change.

Abstract:

The purpose of this study is to investigate the impact of Mexico’s political system on economic inequality between the 32 states of the federation. Longstanding economic divergence between states is occurring despite public finance programmes aimed at reducing poverty. These programmes have not helped poor states develop their economies significantly, and many states have stagnated. At the same time, Mexico’s “diamond regions” or wealthy states have experienced healthy growth. The aim of this study is to show that it is the formal and informal political institutions that keep these programmes from aiding economic development in poor states. A key issue is the ability of poor states to raise finance, which could induce economic development and growth. This is examined in the context of the transition to democracy, with specific focus on political competition. This thesis aims to show the intersections between politics and economics in a growth context, bringing together the Mexican political transition literature and the existing work on subnational economic development. The empirical testing is done with Generalised Method of Moments (GMM), and the statistical analysis is supplemented by correlation and graphical analysis. The influence of political competition on public finance is tested using ordinary least squares (OLS) and GMM. A GMM calculation is also administered to test the relationship between public finance and state wealth. The findings indicate that political influence remains in Mexican public finance. The results suggest that the presence of more than one party in state politics coincides with significantly higher public finance levels than those found in a single-party state. These results also show that poverty and federal finance are significant determinants of each other, meaning that there is a vicious circle between federal funding and state wealth. The impact of federal finance on state wealth is especially salient where there are no specified rules for the spending of the federal money. Finally, some policy suggestions are made. The issues found to require adjustments include the re-election ban, the poor availability of statistical information to decision-makers, and particular details of the federal funding distribution formulae.

"Bathymodiolus" childressi is a mixotrophic mussel from Gulf of Mexico cold seeps. There is no genetic differentiation of mussels among the seeps, suggesting wide dispersal of their larvae. This dissertation describes larval biology, ecology, and recruitment dynamics for "B." childressi. Cleavage is spiral at a rate of one per 3-9 hours, with blastula larvae hatching by 40 hours at 7-8 Ã Ã Â°C. At 12-14 Ã Ã Â°C, D-shell veligers developed by day 8 without being fed. Egg size and shell morphology indicate planktotrophy, but feeding was not observed. Embryos developed normally from 7-15 Ã Ã Â°C and 35-45 ppt. Although survival of larvae declined with temperature, some survived at 25 Ã Ã Â°C. Larval survivorship was similar at 35 and 45 ppt. Oxygen consumption increased from blastulae to trochophores and was higher for "B." childressi than for shallow-water mussel trochophores. Estimated energy content of "B." childressi eggs was greater than the energy content of shallow-water mussel eggs. An energetic model predicts that the eggs provide sufficient energy for "B." childressi trochophores to migrate into the euphotic zone. In fact, "B." childressi veligers were found in plankton tows of surface waters. The influence of recruitment on fine-scale distributions of adults at the Brine Pool cold seep was examined through manipulative field experiments. The "Bathymodiolus" childressi population at this site has a distinct bimodal size structure that shifts across an environmental gradient. New recruits of "B." childressi are abundant in the inner zone, where methane and oxygen are high and sulfide is low, leading to the inference that larvae settle preferentially there. Experiments were placed in the inner and outer zones and 2-m away from the bed. The number of larvae collected in traps did not differ among the three zones, nor did settlement density. Juveniles survived and grew in all zones, but more caged than uncaged juveniles survived. Mortality of uncaged juveniles was similar in all zones, suggesting that predation does not cause the bimodal distribution. These results suggest that the bi-modal distribution cannot be attributed to settlement preferences or juvenile mortality, but instead to migration or early post-settlement mortality.
