Abstract:
Antimicrobial peptides are among the repertoire of host innate immune defenses. In mucosal immunity, the health-disease balance can be greatly modulated by the interplay between host immune factors and colonized microflora. Microbial ecology within dental plaque is constantly shaped by environmental factors present within the oral cavity. Several antimicrobial peptides are detected in saliva and their bactericidal activities against oral bacteria, including Streptococcus mutans, the primary etiologic agent of dental caries, have been clearly demonstrated. However, the role of these antimicrobial peptides in S .mutans ecology and host caries experience is not well-defined. We hypothesized that various strains of S. mutans possess different inherent susceptibility/resistance profiles to host salivary antimicrobial peptides and that host-specific quantities of these peptides may influence plaque colonization by particular S. mutans strains. S. mutans strains from subjects with variable caries experience were tested for susceptibility to a panel of antimicrobial peptides, including HNP-1-3, HBD-2-3 and LL-37, revealing that the susceptibilities of S. mutans to these peptides were strain-specific. S. mutans strains from high caries subjects showed greater resistance to these peptides at varying concentrations than those from caries-free subjects. In addition, when combinations of these peptides were tested, they showed either additive or synergistic interaction against S. mutans. Determinations of the salivary levels of these peptides showed that their concentrations were highly variable among subjects with no correlation to host caries experience. However, positive relationships between the salivary concentrations of HNP-1-3 and MS in dental plaque were found. Additionally, the levels of a number of these peptides in saliva appeared to be positively correlated within an individual. An analysis of the salivary peptide concentrations and the susceptibility profiles of S. mutans strains showed that S. mutans strains obtained from subjects with higher concentration of HNP-1-3 in saliva appeared to be more resistant to HNP-1. Collectively, our findings showed that salivary antimicrobial peptides affect S. mutans ecology by restricting the overall growth of this bacterium within the oral cavity and that their activity may help select resistant strains of S. mutans to colonize within dental plaque. The relative ability of S. mutans to resist host salivary antimicrobial peptides may be considered a potential virulence factor for this species.

Abstract:
According to WHO, the addition of fluoride to milk could be considered as an alternative to water fluoridation for community-based caries prevention in childhood. School-based schemes in developing as well as industrial countries have demonstrated substantial benefits on oral health, but there are limited data available on the local events in the oral cavity after consumption of fluoridated milk. The general aim of the present investigations was to investigate the concentration of fluoride obtained in saliva and dental plaque after ingestion of Fmilk and to explore the possible effects on the oral ecology. A series of controlled studies were performed in vivo in which samples of saliva and dental plaque were collected and analysed with respect to fluoride content, microbial composition and acidogenicity. An in vitro study evaluated the effect on enamel lesion formation. In paper I, significantly increased concentrations of fluoride (p<0.05) were disclosed in saliva 15 minutes after drinking the fluoride-containing water or milk. In the plaque samples however, the F-increase remained significantly elevated still after 2 hours. The availability of fluoride from milk was generally somewhat lower than from water but the differences were not statistically significant in either plaque or saliva. In paper II, the fluoride concentration in plaque was further explored after a single intake or habitual consumption of fluoridated milk together with a regular meal. The results showed that cariesinhibiting levels of fluoride persisted up to 4 hours after intake. There were no significant differences between the single intakes when compared with repeated intakes. In paper III, the influence of fluoridated milk on the salivary microorganisms associated with dental caries was evaluated. No significant alterations of the microflora were found compared with baseline. There was a slight reduction in the proportion of mutans streptococci after 2 and 4 weeks during consumption with fluoridated milk but the difference failed to reach statistical significance. In paper IV it was demonstrated that fluoridated milk significantly (p<0.05) could counteract the lactic acid formation in dental plaque as initiated with sucrose. In paper V, laser fluorescence technique was used to monitor the effect of fluoridated milk on enamel lesion formation in an experimental caries model. The results reinforced previous research and showed a hampering effect of fluoridated milk. No side effects were reported in any of the investigations. The findings of this thesis substantiate that milk is a suitable vehicle for fluoride administration and contribute to the understanding and possible explanations for the anti-caries properties of fluoridated milk. The main conclusions were: a) intake of fluoridated milk resulted in significantly elevated fluoride levels in saliva within the first 15 minutes and up to 4 hours in dental plaque when fluoridate milk was consumed together with meal, b) no significant alteration of the salivary microflora was disclosed after habitual intake of fluoridated milk but a delayed carbohydrate-mediated lactic acid formation in suspensions of dental plaque could be demonstrated, c) the fluoride concentrations in plaque were not negatively influence by the food intake, and d) the in vitro findings advocated that fluoride added to milk reduced enamel lesion formation as assessed by laser fluorescence technique in an experimental caries model.According to WHO, the addition of fluoride to milk could be considered as an alternative to water fluoridation for community-based caries prevention in childhood.

Full text
Abstract:
Phenotypic plasticity, the capacity of a single genotype to exhibit variable phenotypes in different environments, is common in many species. A sample of wild caught Archosargus probatocephalus, also known as sheepshead, from Florida was randomly divided into two treatment groups: one group was fed soft prey, Mercenaria sp. muscle tissue, and the other group was fed hard prey, Mercenaria sp. in the shell, for 365 days. It was hypothesized that the sheepshead fed hard prey would have a thicker tooth enamel layer containing more calcium, and therefore be stronger than the tooth enamel layer of those fed soft prey items. Additionally, the mean functional jaw surface area, the percentage of tooth coverage of functional jaw surface, number of teeth per jaw, correlation between standard length and mean total tooth height, and the combined surface area of the teeth, when compared between the two treatments, should be greater in the hard prey treatment. The seventeen jaws of two prey groups were acquired postmortem and each jaw was divided into four quadrants. The largest tooth in each quadrant was removed from the jaw, longitudinally sectioned, and examined using scanning electron microscopy (SEM) to measure the enamel and dentin layers. Using the SEM backscatter electron detector the elemental composition of the different layers was determined at multiple locations. Finally, data was analyzed using analyses of variance (ANOVA’s) to compare mean tooth height, calcium content in enamel and dentin layers, mean functional jaw number of teeth per jaw, and upper to lower jaw overall enamel and dentin thickness between each treatment. Phenotypic plasticity was identified in three areas: percentage of jaw surface covered by teeth, a positive correlation between total tooth height and enamel height in hard prey treatment, and a positive correlation between total tooth height and soft prey treatment dentin height; but not in the other areas studied. It is apparent that phenotypic plasticity can increase an individual’s ability to survive in a variable food resource environment by changing some aspects of tooth morphology, but the ability to change in response to stimuli was not found in all areas of tooth structure. i

Individuals of the same species have morphological, physiological and behavioral characteristics that determine when and where they will exist and how they will interact with individuals of other species. The ecomorphological diversity of anuran tadpoles make them great study subjects, as the resources use patterns (ecology) and the phylogenetic relationships among species can be inferred from the phenotypic properties. The influence of contemporary factors on the structure of tadpoles communities has been intensively studied for decades, but the use patterns and partitioning of food resources, have not received the same attention from researchers. Little is known about the ecology and feeding behavior of tadpoles, including its biomechanics, the influence of abiotic factors on feeding behavior, as well as the behavioral plasticity exhibited by tadpoles in the exploitation of food resources. These issues were investigated during the PhD and the results of the work developed during the course of this period are presented in this Dissertation In the first chapter, we verified whether the carnivorous tadpole of Leptodactylus labyrinthicus would adjust their feeding kinematics to maximize food consumption when feeding on alternative food sources. Our results indicate that, depending on the food source to be explored, the tadpoles may exhibit different feeding behavior: to consume the food particles suspended in the water surface, the tadpoles exhibit the filter-feeding behavior; in contrast, to consume food particles that are attached to submerse surfaces, tadpoles use the scrape feeding behavior. Filtering and scraping feeding behaviors are quantitative and qualitatively distincts, i.e. these feeding behaviors kinematics and the shape of the oral disc during feeding show distinguishable features. In the second chapter, we tested the hypothesis that changes in the water mean temperature would have differential 15 effects on the feeding kinematics of tadpoles of two anuran species: Rhinella schneideri, whose tadpoles are benthic, and Trachycephalus typhonius, whose tadpoles are nektonic. Our results indicate that the temperature affects the kinematics of the scrape feeding behavior. However, the temperature effect on kinematics variables may depend on the species, so the changes are not in the same direction (i.e. temperature may have a positive effect on some kinematic variables but negative effects on others). Finally, in the third chapter, our aim was to verify whether the ecological and morphological influences on feeding behavior reflect the phylogenetic relationship among species.
Indivíduos de uma mesma espécie possuem características morfológicas, fisiológicas e comportamentais que determinam quando e onde eles poderão existir e como interagirão com indivíduos de outras espécies. A diversidade ecomorfológica de girinos de anfíbios anuros os tornam ótimos organismos de estudo, já que os padrões de uso de recursos (ecologia) e as relações filogenéticas entre as espécies podem ser inferidas a partir das propriedades fenotípicas. A influência de fatores contemporâneos sobre a estrutura das comunidades de girinos tem sido intensamente estudada há décadas, mas os padrões de uso e partilha de recursos alimentares não têm recebido a mesma atenção dos pesquisadores. Pouco se sabe sobre a ecologia e o comportamento alimentar dos girinos, incluindo a biomecânica do comportamento alimentar, a influência de fatores abióticos sobre o comportamento alimentar, além da plasticidade comportamental exibida pelos girinos na exploração dos recursos alimentares. Estas questões foram investigadas durante o Doutorado e os resultados do trabalho durante ao longo deste período são apresentados na presente tese, que compreende três capítulos. No primeiro, verificamos se o girino carnívoro de Leptodactylus labyrinthicus ajusta seu comportamento alimentar para maximizar o consumo de alimento obtido a partir de fontes alimentares alternativas. Os resultados indicam que, dependendo da fonte alimentar a ser explorada, os girinos podem adotar comportamentos alimentares distintos: para consumir alimentos disponíveis em suspensão na água, os girinos exibem o comportamento de filtração; já para consumir alimentos aderidos em superfícies submersas, os girinos utilizam o comportamento de raspagem. Tais comportamentos alimentares são discerníveis com relação às suas cinemáticas e aos formatos que o disco oral assume durante a alimentação por filtração e por raspagem. No segundo, testamos a 13 hipótese de que mudanças na temperatura média da água teriam efeitos diferenciais sobre o comportamento alimentar de girinos de duas espécies de anuros: Rhinella schneideri, que possui girinos bentônicos, e Trachycephalus typhonius, cujos girinos são nectônicos. Os resultados indicam que a temperatura afeta a cinemática do comportamento alimentar de raspagem. No entanto, devido à interação entre espécie e temperatura, o efeito da temperatura sobre as variáveis cinemáticas pode não produzir uma variação no mesmo sentido. Finalmente, no terceiro capítulo, nosso objetivo foi o de verificar se a influência dos fatores ecológicos e morfológicos sobre o comportamento alimentar dos girinos reflete as relações filogenéticas entre as espécies.

Abstract:
Streptococcus gordonii is a primary coloniser of the tooth surface where it efficiently ferments carbohydrates at pH levels above 6.0. By not being able to maintain the pH of dental plaque to a level required for enamel dissolution, the dominance of S. gordonii in dental plaque is considered a sign of a healthy oral cavity. However, upon entering the bloodstream and encountering a rise in pH, S. gordonii may become pathogenic, being one of the major causative organisms associated with infective endocarditis. Proteome analyses of S. gordonii grown at steady state in a chemostat allowed the phenotypic changes associated with alterations in pH levels characteristic of these two environments to be determined. As an initial starting point to this study, a two-dimensional electrophoresis (2- DE) reference map of S. gordonii grown at pH 7.0 was produced. Although only 50% of the S gordonii genome was available in an annotated form during the course of this study, the closely related Streptococcus pneumoniae genome (with which S. gordonii shares 97.24% DNA sequence homology) had been completed in 2001. The use of both of these databases allowed many of the S. gordonii proteins to be identified by mass spectrometry. Four hundred and seventy six protein spots, corresponding to 250 different proteins, or 12.5% of the S. gordonii proteome, were identified, giving rise to the first comprehensive proteome reference map of this oral bacterium. Of the 250 different proteins, 196 were of cellular origin while 68 were identified from the extracellular milieu. Only 14 proteins were common to both compartments. Of particular interest among the 54 uniquely identified extracellular proteins was a homologue of a peptidoglycan hydrolase that has been associated with virulence in S. pneumoniae. Among the other proteins identified were ones involved in transport and binding, energy metabolism, translation, transformation, stress response and virulence. Twelve cell envelope proteins were identified as well as 25 others that were predicted to have a membrane association based on the presence of at least one transmembrane domain. The study also confirmed the existence of 38 proteins previously designated as �hypothetical� or with no known function. Mass spectral data for over 1000 protein spots were accumulated and archived for future analysis when sequencing of the S. gordonii genome is finally completed. Following the mapping of the proteome of S. gordonii, alterations in protein spots associated with growth of the bacterium at pH intervals of 0.5 units in the pH range 5.5 - 7.5 were determined. Only 16 protein spots were shown to be significantly altered in their level of expression despite the range of pH studied. Among the differentially expressed proteins was a manganese-dependent inorganic pyrophosphatase (PpaC), which regulates expression of adhesins required for coaggregation. The expression of PpaC was highest at pH 6.5 - 7.0, the pH of a healthy oral cavity, indicating that PpaC may play an important part in dental plaque formation. Another differentially expressed protein was the heat-inducible transcription repressor (HrcA). Alterations in HrcA were consistent with its role as a negative repressor in regulating heat-shock proteins at low pH, even though no changes in the level of heat-shock proteins were observed as the pH declined. This result gave rise to the hypothesis that the possible reason cariogenic bacteria, such as Streptococcus mutans, can out compete S. gordonii at low pH might simply be due to their ability to manipulate their proteome in a complex manner for survival and persistence at low pH, unlike S. gordonii. This may imply some prevailing level of genetic regulation that is missing in S. gordonii.

Abstract:
Inom svenskämnesdidaktisk forskning har digitala medier i undervisningen börjat få ett allt större fäste. Det som emellertid saknas är poddars plats i den digitala lärmiljön. Syftet med föreliggande undersökning var således att studera hur en didaktisk design som inkluderar poddar kan konstrueras för att motivera elever till muntlig framställning. Det empiriska materialet utgjordes av en triangulering baserat på enkäter, fokusgruppsamtal och observationer med etnografisk ansats. Målgruppen för undersökningen var en klass bestående av 15 elever från en kommunal gymnasieskola. För att undersöka huruvida motivationen hos eleverna förändrades, gjordes ett för- och eftertest utifrån en motivationsmodell. Modellen innehöll fem dimensioner, samtliga behandlades i både enkätundersökningen och under fokusgruppsamtalen. Resultatet visade att eleverna blev motiverade till muntlig framställning när poddar inkluderades i undervisningen. Vidare styrkte resultatet vikten av varierande undervisning, där alternativa strategier kopplade till muntlig framställning nyttjas. Undersökningen bidrar därför med ny kunskap om hur denna medieform formar villkor och möjligheter för kunskap i en allt mer digitaliserad skola.
Within didactic research regarding Swedish as a subject, digital media has started to gain a lot of ground. However, the podcasts' place within the digital learning environment is missing. The purpose of the present study was therefore to study how a didactic design that includes podcasts can be constructed to motivate students to perform oral presentations. The empirical material was constituted by a triangulation based on surveys, focus group discussions and observations with ethnographic approaches. The target group for the study was a class consisting of 15 students from a public upper secondary school. In order to investigate whether the students' motivational levels were changed, a pre- and a post test were conducted using a motivational model. The model contained five dimensions which were all treated in the survey and the focus group discussions respectively. The result showed that podcasts can make students more motivated for oral presentations. Furthermore, the result stressed the importance of a varied pedagogy where alternative strategies linked to oral presentations are utilized. Therefore, the research contributes with new knowledge regarding how this form of media creates conditions and options for acquiring knowledge in an increasingly digitalized school.

A admissão do conhecimento científico como forma mais legítima de entendimento da realidade nos coloca diante da exclusão das infinitas manifestações de saber que existem no mundo em uma lógica de monocultura dos saberes. Para confrontar essa realidade podemos constatar a nossa diversidade epistemológica por meio de uma ecologia dos saberes. Neste sentido a ciência não é mais percebida como a principal forma de entendimento da realidade, além dela há infinitos saberes com voz suficiente para dialogar de forma horizontal com a ciência, dentre eles destacamos a capoeira angola. Esta é percebida aqui como uma manifestação da cultura popular afro-brasileira que conta com mestras e mestres na transmissão de saberes via oralidade. Daí surge nosso principal objetivo que é refletir sobre a capoeira angola como saber a partir daquilo que emerge dos processos de ensino e aprendizagem do grupo nZambi de capoeira angola em Florianópolis - SC. Assim foi possível evidenciar o trabalho de uma das primeiras mestras de capoeira angola, Elma Silva Weba, a mestra Elma. Para dar cabo desta demanda realizamos um estudo de caso no ambiente do grupo nZambi de capoeira angola em Florianópolis - SC. O estudo de caso foi possível através de uma pesquisa de campo, onde participamos durante três meses das atividades do grupo por meio da observação participante, sendo que a entrevista semi-estruturada e o relato oral foram também instrumentos de coleta de dados. No grupo nZambi de capoeira angola em Florianópolis - SC, nos deparamos com formas sutis de transmissão de saber em que o capricho e o silêncio eram elementos fundamentais de uma experiência coletiva e comunitária, possível por meio do aprendizado da cooperação. _______________________________________________________________________________________ ABSTRACT
The admission of scientific lore as the most legitimate way of understanding reality places us up the exclusion of numerous knowledge expressions that exist in the world, in a knowing monoculture logic. To confront this reality we can think over the finding of our epistemological variety by means of a knowledges’ ecology. In this sense, science isn’t perceived anymore as the main manner of understanding reality, further there are numerous knowledges that hold sufficient voice to dialog horizontally with it, among them we highlight capoeira angola. This one is understood here as a manifestation of afro-brazilian popular culture the counts with male and female master in the oral transmission of knowing. There from arises our main objective – think about capoeira angola as a knowledge from what emerges in the guideline/ apprenticeship processes of nzambi capoeira angola group in Florianópolis – SC. Thus it was possible to evidence the task of one of the first capoeira angola female masters, Elma Silva Weba, master Elma. To accomplish this demand a case study was realized in the group environment. This case study was possible by means of participating observation, and the semi – structured interview and the oral account were also data collection tools. In nZambi capoeira angola group we acrossed subtle ways of propagating knowledge in which whim and silence were fundamental elements of a collective and communitary expererience, possible by means of cooperation learning.

Esta dissertação partiu da idéia de que os modelos paisagísticos atualmente adotados nas margens do Lago Paranoá não estão contribuindo adequadamente para a manutenção dos ecossistemas nativos. Neste contexto a restauração de corredores verdes, alocadas em posições estratégicas através da ligação de áreas de proteção ambiental, pode atuar como uma estratégia viável para a conservação da biodiversidade, pois diminui os efeitos negativos da fragmentação de habitats. Foi descrito como a ecologia, na qualidade de um novo paradigma, viria a influenciar a práticas projetuais, resultando em ações mais equilibradas com o meio ambiente. Também foram apresentados alguns projetos paisagísticos, no Brasil e no exterior, que incluíram a conservação ambiental como uma de suas principais preocupações. O comprometimento ambiental das margens dos corpos d’água, talvez seja o maior exemplo de como essa expansão urbana tem afetado e degradado os processos naturais no Distrito Federal. Neste sentido, o estudo da orla do Lago Paranoá, das estratégias para sua conservação e sua legislação pertinente, mostrou-se importante para a avaliação da exploração de seus recursos naturais. Foi realizada uma análise da ocupação da orla do lago ao longo de várias décadas e das propostas e das diretrizes do processo de implantação do Projeto Orla. A análise paisagística baseou-se em um estudo de caso específico, a orla do Lago Sul, delineada por uma metodologia inspirada em técnicas consagradas do paisagismo. Como conclusão, acredita-se que as atuais ocupações nas margens são prejudiciais a manutenção dos ecossistemas nativos, exigindo intensas modificações, que resultariam em amplos ganhos para a sociedade e para o meio ambiente. Foi verificada que é possível a implantação de um corredor verde na área de estudo, com a devida ligação de áreas remanescentes da vegetação nativa do cerrado e a utilização de um paisagismo mais preocupado com o meio ambiente. _______________________________________________________________________________________________________________ ABSTRACT
This master thesis started from the idea that the landscape’s models currently adopted on the shore of the Lake Paranoa aren’t contributing properly for the maintenance of the native ecosystems. In this context, the restoration of green corridors, allocated in strategic positions by the connection of environmental preservation areas, could act as feasible strategy in the conservation of biodiversity, as it decreases the negative effects of habitats’ fragmentation. It was described how ecology, in the quality of a new paradigm, would influence the projetual practices, resulting in actions that respect the environment. It was also presented some landscape’s projects, in Brazil and abroad, which has the environmental conservation as one of its major concerns. The environmental degradation of the watersheds maybe is the bigger example of how the urban expansion has affected and degraded the natural processes in the Federal District. By this point of view, it is very important the study of the shore of Lake Paranoa, of its strategies of conservation and its referred laws. It was done an analysis of the occupation of the shore of the lake along several decades and the plans and propositions of the process of implementation of “Projeto Orla”. For the landscape analysis of the shore, it was chosen the shore of Lago Sul, using a methodology inspired in well-known landscapes’ techniques. As a conclusion, it is believed that the current occupations on the shore damage the maintenance of native ecosystems, demanding modifications and high investments that will result in great wins for the society and the environment. It was also verified that it is possible the implementation of green corridors in the shores of Lago Sul, using the connection of reminiscent areas of native vegetation of “cerrado” and the utilization of a landscape more concerned with the environment.

Environmental History comes to meet the voices in the streets and, at the same time, build bridges between other disciplines and study fields. This new idea of History was born in the USA in the 1970s and it is already present in all continents; in Brazil this area is on growth. So, in this work we sought to reconcile the history of Tambaba Settlement and APA Tambaba under the view of Environmental History. By taking into account that the settlement was created recently, the same way as APA, and that many of the actors involved in those creations can still be listened, we chose Oral History to know and understand the formation processes of the preservation unit and rural community. The dynamics provided by the testimonials has fostered the knowledge on social and environmental divergences, which led to identify impacts caused by anthropization of the natural mean their prospects of sustainable use.
A História Ambiental vem para atender as vozes das ruas e ao mesmo tempo se interrelacionar com outras disciplinas e áreas de estudo. Esse novo modo de concepção da história que enquanto disciplina acadêmica nasceu nos EUA na década de 1970, já está presente em todos os continentes, no país está em crescimento. Assim procurou-se nesse trabalho conciliar a história do Assentamento e da APA Tambaba pela ótica da História Ambiental. Considerando o fato de a criação do assentamento ser recente, da mesma forma que a criação da APA, e de que muitos dos atores envolvidos nessas criações ainda poderem ser ouvidos, optou-se pelo uso da História Oral para conhecer e compreender os processos de formação da unidade de conservação e comunidade rural. A dinâmica proporcionada pelos depoimentos fomentou o conhecimento de divergências socioambientais, as quais levaram a identificações de impactos causados pela antropização do meio natural suas perspectivas de uso sustentável.

Abstract:
Preservationist conservation created a legacy of national parks and protected areas that were surrounded by local people dispossessed of their land and denied the rights to use the resources they had previously relied upon. Although conservation is now shifting towards a more participatory approach, research gaps still exist in determining the meaning of 'the environment' and the role of local means of conservation in rural communities in South Africa. This study focused on children's cultural environmental narratives from two rural villages in the Eastern Cape, South Africa. Children from grades 4, 7 and 10 were involved in the study, and adult family members, local experts and village elders were included in the study to allow for comparison between children's and adult's narratives and to realise what Local Ecological Knowledge (LEK) was being passed on. This thesis considers children's use of the environment for play and their sense of place as key methods in ascertaining children's environmental narratives and perceptions. At both field sites, local experts and community elders possessed a wealth of cultural environmental narratives, but these narratives were not necessarily being passed on. Changing household structures and other socio-economic factors influence cultural environmental practices, which in turn have an impact on the cultural environmental narratives being passed down. In many cases, parents' safety fears strongly impacted upon children's access to the environment, resulting in gendered environmental knowledge. The study compared differing vegetation types and degrees of environmental access. The differing environments produced similar cultural environmental narratives, leading to new understandings in community environment relationships. Children living near the state administered forest had significantly less environmental knowledge, bringing about questions of sustainable bio-cultural diversity in the future. The recognition of cultural environmental values is especially important in the rural areas of South Africa, where unemployment and increased poverty levels have led to greater dependence on natural resources for social, economic and cultural purposes. It is proposed that local cultural environmental narratives and landscape perceptions be included into community conservation and environmental education policies and programmes to provide local solutions to the problem of biodiversity conservation in local contexts.

This study was conducted among three coastal communities: Aritingui, Taberaba and Tavares, located on the right of the estuary of Mamanguape River (EMR) in Paraíba, and incorporated in the Environmental Protection Area of the namesake river. Its main objective is to study the local ecological knowledge and use of wildlife resources by fishermen and collectors of these communities. This work had its theoretical and methodological focus in Ethnoecology. The sampling was intentionally non-random, where the respondents were previously defined according to the dedication and frequency in fishing activities. The fieldwork took place between the months of October 2008 and November 2009. Free unstructured interviews and direct observations were conducted with the purpose of studying aspects of the interaction between the target communities and the mangrove-estuary complex. From the free unstructured interviews, structured interviews were conducted to collect data on the exploration, utilization and conservation of resources from the mangrove-estuary of Mamanguape River. The data were analyzed using the model of unity of the various individual skills seeking to juxtapose ethnoecological to scientific knowledge. In developing the mental maps, one key informant was chosen in each community and each was asked to design, with reference to their community, the estuary with the main collection of fishery resources. The oral map was obtained from tours guided by key informants along the EMR and was to appoint the main sampling sites. Fishermen cited 13 folk generic species: 6 species of fish, 5 crustacean species and 2 species of mollusks. The species of fish most often cited was Bathygobius soporator, of crustacean was Cardisoma guanhumi and of mollusk was Crassostrea sp., which are used for consumption, with marketing only of the surplus. Fishermen perceive the spatial distribution of wildlife resources and categorize them in etnohabitats ( mangrove fish , Camboa fish ), microhabitats ( fish of strain , fish of hole and fish of lodge ) and vertical distribution ( ground fish and water flower fish ). They also showed a wide knowledge of the trophic and reproductive behavior of the most explored species. From the mental and oral maps, accurate spatial perception related to fishing sites and grooming was registered. The fishermen in the Aritingui, Taberaba and Tavares communities show detailed ethnobiological knowledge, consistent with Western science. The knowledge that these fishermen hold on the distribution of resources and its ecology, and environmental perception, is a tool valuable enough to be embedded in socio-economic plans as well as in management, conservation and sustainable use of wildlife studies.
Este estudo foi realizado junto a três comunidades ribeirinhas: Aritingui, Taberaba e Tavares, localizadas na margem direita do estuário do rio Mamanguape-PB, e inseridas na Área de Proteção Ambiental do rio homônimo e teve como principal objetivo estudar o conhecimento ecológico local e o uso dos recursos faunísticos por pescadores e catadores destas comunidades. Este trabalho teve seu enfoque teórico-metodológico fundamentado na Etnoecologia. A amostragem foi não-aleatória intencional, onde foram pré-definidos os entrevistados, em função da dedicação e freqüência na atividade pesqueira. Os trabalhos de campo ocorreram entre os meses de outubro de 2008 e novembro de 2009. Foram realizadas entrevistas livres não estruturadas e observações diretas, com a finalidade de se conhecer aspectos da interação entre as comunidades-alvo e o complexo estuário-manguezal. A partir das entrevistas livres não estruturadas, foram realizadas entrevistas estruturadas, visando obter dados sobre a exploração, utilização e conservação dos recursos provenientes do complexo estuário-manguezal do Rio Mamanguape. Os dados foram analisados segundo o modelo de união das diversas competências individuais buscando justapor o conhecimento etnoecológico ao conhecimento científico. Para a elaboração dos mapas mentais, foi escolhido um informante-chave de cada comunidade, e a cada um deles foi pedido que desenhasse, tendo como referência a sua comunidade, o estuário com os principais pontos de coleta dos recursos pesqueiros. O mapa oral foi obtido a partir de turnês guiadas pelos informantes-chaves ao longo do ERM e consistiu em nomear e georreferenciar os principais locais de coleta. Os pescadores citaram 13 genéricos folk, sendo 6 espécies de peixe, 5 espécies de crustáceos e 2 espécies de moluscos. A espécie de peixe mais citada foi Bathygobius soporator, a de crustáceo foi Cardisoma guanhumi e a de molusco foi Crassostrea sp., sendo estes recursos utilizados para consumo, com a comercialização apenas do excedente. Os pescadores percebem a distribuição espacial dos recursos faunísticos e os categorizam segundo etnohabitats ( peixes de mangue , peixes de camboa ), microhabitats ( peixes de cepa , peixes de buraco e peixes de loca ) e distribuição vertical ( peixes de chão e peixes da flor d água ). Também demonstraram amplo conhecimento sobre o comportamento trófico e reprodutivo das espécies mais exploradas. A partir dos mapas mentais e do mapa oral, ficou registrado a apurada percepção espacial relacionada aos sítios de pesca e catação. Os pescadores das comunidades de Aritingui, Taberaba e Tavares possuem conhecimento etnobiológico detalhado e coerente com a ciência ocidental. O conhecimento que estes pescadores detêm sobre a distribuição dos recursos e sua ecologia, além de sua percepção ambiental, constitui-se em uma ferramenta valiosa que é suficiente para ser incorporada tanto em planos de desenvolvimento sócio-econômicos quanto em estudos de manejo, conservação e utilização sustentável da fauna local.

Abstract:
This thesis examines Tongan traditional history, tala-e-fonua, a vernacular ecology-centred historico-cultural concept, handed down through generations by word of mouth. As a Tongan Weltanschauung, tala-e-fonua can be regarded as an indigenous account of the land and its people, a symbolised human landscape. In this anthropo-ecological context, I examine the continuity of the social and the natural, and how the dialectic between structure and event are orally transmitted through culture and history. The first part introduces the issues by examining the formal characteristics of tala-e-fonua and its place in scholarship; moreover, it focuses on the dynamic of permanence and change, considering how convention is risked in action through which order is restored in the event. These issues are put in context in chapter one, where the formally complementary and opposed connections between myths and history are examined in synchronic and diachronic terms within a social context. The early traditional-mythological history, part two, delves into the issue of origin, dealing with the mythical past historically. In chapter two, the Tongan cosmogony and cosmology are explicated in terms of the Tongan creation myth, ta la tu pu ’a , where the local and regional origin of the concept is further traced in terms of the enforced divine power transference amongst the three principal deities. Furthermore, it addresses how hierarchy was risked within the interplay of religion and politics, and the way it was developed in Tonga in terms of the transformation of two regional cultures, Pulotu and Langi, over Maama or Lolofonua. The middle traditional-theological history, in part three, examines the political hegemony of the Tangaloa line over the Havea Hikule’o and Maui Motu’a lineages, respectively representing Pulotu and Maama. Chapter three is thus concerned with internal strife within the Tangaloa house, which culminated in the rise of the first Tu’i Tonga, god and king, ’Aho’eitu, ’Eiki and Hau, who unified Tonga against Samoa and the rule of the Tu’i Manu’a. In part four, the later traditional-classical history is articulated in terms of the emergence of permanent social institutions of greater economic and political significance in Tongan society. The birth of the Tu’i Tonga empire, Pule9anga Hau 9o e Tu9i Tonga, linking centre and periphery through maritime activities, preceded by a period of local nation building, is examined in chapter four. Chapter five discusses imperial expansion beyond Tonga via conquest, which, through antagonism, was changed to conquest-alliance formation. With the period of alliance formation which followed, chapter six considers imperial decline in conjunction with the fall of sacred Tu’i Tonga antithesised by the respective rise of the new secular Hau, Tu’i Ha’atakalaua and Tu’i Kanokupolu, into political supremacy. Finally, part five draws implications from the thesis as a whole. Having socially articulated through poetry the literal and symbolic relationships between the three royal titles, Tu’i Tonga, Tu’i Ha’atakalaua and Tu’i Kanokupolu, in geographic terms, chapter seven focuses on the cultural and historical continuity of past and present. Recognising this philosophical character of human affairs, it is concluded that the exchange between structure and event manifests itself on the level of the dialectic between culture and history.

Abstract:
The evolution of jaws in cichlid fishes of the East African Great Lakes is a textbook example of adaptive radiation in vertebrates. Karl Liem postulated that this adaptive radiation has been possible due to the functional decoupling of two cichlid functional units – the pharyngeal jaw (PJ) and the oral jaw (OJ). This functional decoupling of the jaws has enabled the OJ to be relieved of its dual role of prey capturing and processing and has allowed the PJ to take on the role of prey processing. As a result, African cichlids have adapted the morphology of their functional units (i.e., oral jaws) to specialize in a feeding mechanism best suited for their habitat. However, global morphological changes (across the OJ and PJ) are understudied, especially, at the genetic level. In this study, two rock dwelling species of African Cichlids from Lake Malawi were used - Labeotropheus fuelleborni (LF) and Tropheops “red cheek” (TRC). Both species have distinct craniofacial morphologies for specialized benthic feeding (LF) and for generalized feeding (TRC). This morphological variation allowed us to investigate the functional decoupling of the jaws by studying differences in bone shape and muscle volumes in an F5 hybrid population. Strong phenotypic correlations were observed between and within the tissues of the OJ and PJ. Further, to identify phenotype to genotype associations, a Quantitative Locus (QTL) analysis and a fine mapping analysis was conducted. The results show some evidence of overlapping genetic control (i.e., pleiotropy) suggesting some genetic coupling between the two jaws.

Abstract:
The main aim of this study is to investigate the relationship between landscape, memory and heritage. It aims to establish that landscape is not only an inseparable part of the intangible process of memory, but also the formation and perpetuation of cultural and individual identity. The composition of heritage, including the sociocultural and biophysical, is therefore a complex result of varying interactions between memory and landscape, as perceived by the living custodians. The intangible values of meaning, memory, lived experience and attachment, in relation to people's connection to locality and landscape, are traced back to the tangible fabric of place. Through means of qualitative and quantitative anthropological fieldwork methods and an extensive literature review, the sociocultural profile of the Mpondo is briefly documented. The subsequent case study explored a site in the Eastern Cape on Ngquza Hill, where the oral traditions and memories connected to the site are mapped. These elements were accessed through employing the theories of mnemotechnics.

Abstract:
Invasive plants are generally understood as alien taxa that have a tendency to displace native species and decrease biodiversity through formation of dense monoculture. Although in recent years many studies have been conducted in invaded communities, there are still alien plant species which ecology and invasive potential have not been sufficiently examined. In addition, a lot of research focus on ground-vegetation, whereas, soil seed bank and physicochemical properties of soil play a major role in maintaining floristic diversity. Rudbeckia laciniata is an herbaceous perennial species from the family Asteraceae. It is native to North America, however it was brought to the Europe as an ornamental plant in the 17th century. Nowadays it spreads into semi-natural and natural habitats across the Europe and Asia. The aim of this study is to investigate how Rudbeckia laciniata affects three components of invaded communities: 1) native ground-vegetation; 2) size and composition of soil seed bank; and 3) physicochemical soil properties. The studies were conducted in two types of habitats, which differ in humidity - meadows within and outside of a river valley. Each site was divided into three zones (control, transition and invaded), with different coverage of R. laciniata - from zero in the control zone to more than 70 percent in the invaded zone. In each zone, 100 phytosociological relevés were recorded and 125 soil samples were collected. To estimate size and composition of soil seed bank, seedling germination method was used. The observation of seedling growth was carried out in laboratory condition for one year. To estimate chemical and physical soil properties, the acidity, organic matter, and main cations were measured. To quantify the differences between each zone and meadow type, diversity indexes were calculated as well as PERMANOVA and SIMPER analysis were applied. The statistical analysis show significant differences between each zone in term of ground vegetation. The plots with a high abundance of R. laciniata are characterized by the lowest species richness and functional diversity. The plant traits analysis shows that the share of competitors and anemochores decrease along with with Rudbeckia abundance, while the share of leafy stem plants increases. In both types of meadows, the transition zone is more similar to the control zone than the invaded one. In the soil seed bank, the number of all propagules was several times higher in the invaded zone than in the control zone, in both habitat types. However, this is due to the huge number of Rudbeckia seeds. The number of other seeds, as well as species richness in each zone were similar. In the transition zones the number of Rudbeckia seeds was significantly lower, and no seeds of this species were found in the control zone, both on the meadow within and outside of the river valley. These results indicate high reproduction ability of R. laciniata with a concurrent lower dispersion potential. Majority of the invader seeds were in the surface layer of soil, which confirms the tendency to form "short-term persistent" seed bank by R. laciniata. The effect of R. laciniata on the physicochemical properties of the soil was not confirmed.

Abstract:
El grupo de teatro foro “Les Yuyeres” está conformado por estudiantes, graduadas, no docentes y docentes de carreras de arte, sociales y humanas de la Universidad Nacional de Córdoba (UNC), la Universidad Nacional de Villa María, la Universidad Provincial de Córdoba y la Universidad Nacional de La Rioja. El equipo viene trabajando desde 2015 en el desarrollo de proyectos de investigación-extensión-producción de teatro foro sobre medicinas naturales y problemáticas ecosistémicas y ambientales en las sierras de Córdoba, con el objetivo de recuperar conocimientos ancestrales y ponerlos en circulación en comunidades rurales a través de entrevistas a pobladores, de talleres y de obras de Teatro Foro. En el siguiente trabajo abordaremos los procesos de creación en la obra “Tengan el patio regao”, basándonos en los pilares metodológicos de las experiencias previas del grupo que son: las entrevistas a pobladores, la construcción de dramaturgia a partir del relato oral y la función de teatro foro en los territorios.
