Faunal homogenization and differentiation occur when geographic regions show increased or decreased, respectively, similarity to each other in species composition owing to introductions and extinctions or extirpations. I used species presenceabsence data for "native" (i.e., estimated species compositions before European settlement) and "total" (i.e., including nonnative fishes and extinctions) faunas to examine faunal similarity of freshwater fishes among aquatic ecoregions of British Columbia and among Canadian provinces and territories. British Columbia ecoregions showed faunal differentiation as the mean Jaccard's faunal similarity coefficient for total faunas was significantly less than that for native faunas (31.4% versus 34.9%), but some ecoregions showed homogenization (e.g., Vancouver Island and Columbia River ecoregions). Comparisons across Canada showed low but significant homogenization; average pairwise Jaccard's coefficient was higher in total versus native faunas (29.1% similarity versus 27.8%, respectively). British Columbia's fish fauna increased the most in similarity to other areas (except the three territories), with an average increase of 4.9%. Native faunal similarity patterns are part of Canada's natural heritage but are threatened by human-mediated increases in nonnative species and extinctions. This analysis provides a baseline to track changes in inter regional faunal relationships at different geographic scales.

San Josecito Cave (2250 m elevation) is located nearby Aramberri, Nuevo León, northeastern Mexico, with excavations occurring in 1935–1941 and 1990. It is a paleontological cave and the significance of its faunal data rests in the understanding of the Quaternary ecosystems of the Mexican Plateau and the Southern Plains. This significance is underpinned by a consideration of associated stratigraphic and geochronological data. The fauna is composed of mollusks, amphibians, reptiles, birds, and mammals. More than 30 extinct vertebrate species have been identified, constituting one of the most important Quaternary localities in the Americas. Radiocarbon dates and faunal correlations indicate the excavated deposits represent an interval of time between 45,000 and 11,000 14C years BP. The current synthesis demonstrates that the previous view of the assemblage as a single local fauna is erroneous and that, instead, several successive local faunas are present within a stratigraphic framework. This finding underscores the need for detailed studies of single localities in building paleoenvironmental models. As a corollary, results point to the necessity of including all vertebrate classes represented from a locality in building those models. In addition, the field and analytical methodologies demonstrate the importance of very detailed paleontological excavations, with precise spatial and temporal controls, to assess the taphonomic history of a locality, construct a stratigraphic and geochronological framework, and infer the paleoecological conditions during the time span considered based on the number of local faunas represented. The recognition of San Josecito Cave as an important Late Pleistocene vertebrate paleontological locality is enhanced with the consideration of its faunal data for paleoenvironment reconstruction and possible contribution to Quaternary paleoclimatic modeling.

Tropical deforestation often produces landscapes characterized by isolated patches of forest habitat surrounded by pasture, agriculture, or regrowth vegetation. Both the size and the distribution of these forest patches may influence the long-term persistence of faunal species. There is, therefore, a pressing need to understand faunal responses to patterns of forest fragmentation in tropical systems. The Biological Dynamics of Forest Fragments Project (BDFFP) provides a wealth of autecological information and spatially explicit data describing habitat use and movement of fauna between Amazonian forest fragments. Using data from the BDFFP and other studies in the Amazon Basin, this paper reviews the information available on tropical insects, frogs, birds, primates, and other mammals that can be used to identify and classify species most at risk for extirpation in fragmented forests.Key words: Amazonia, habitat fragmentation, rainforest, fauna, Biological Dynamics of Forest Fragmentation Project.

Cambrian trilobite faunas from northern India provide data critical for assessing earliest Phanerozoic paleogeography and for constraining tectonic models of Himalayan evolution. Previous investigations suggest that Indian Middle Cambrian trilobite faunas, collected from basins 500 km apart, are strikingly different. The Kashmir fauna, in the west, shows supposed faunal affinities with northern China, while the Spiti fauna, in the east, was considered of European affinity. This counterintuitive faunal distribution in adjacent basins might suggest that the area was made up of several micro-contininents during Cambrian time. Although frequently neglected, this interpretation has major implications for models of Himalayan mountain building, as most models assume a passive northern margin of India throughout the Phanerozoic.Original type material from Kashmir and Spiti and fresh collections from intermediate localities in the Zanskar valley have been evaluated using a new statistical/computer-graphic method which removes the effects of tectonic deformation. Results show that the supposed taxonomic distinctness of the Kashmiri and Spiti faunas is largely superficial. Previous lack of appreciation of deformation has lead to: 1. over-estimation of the number of taxa present; 2. misidentification of many taxa; 3. spurious correlations with other faunas; 4. inaccurate age estimates. The revised assessment indicates that: 1. approximately 12 species of polymerid trilobites are present in the Middle Cambrian of north India; 2. 3 polymerid trilobite species are common to both Kashmir and Spiti faunas; 3. much of the Spiti fauna is significantly older than the Kashmiri fauna; 4. faunal differences between coeval deposits from the two basins are best explained as biofacies differences related to an offshore proximality trend; 5. species show patterns of developmental flexibility similar to that recently reported in other Cambrian trilobites. The faunas do not suggest that Kashmir and Spiti were part of separate continents during the Cambrian.The morphology of Middle Cambrian faunas from Kashmir, Zanskar and Spiti suggests that all polymerid species were benthic and share morphotypes characteristic of trilobites from slope environments. Lithologic evidence suggesting that Kashmiri faunas were deeper water than those from Spiti is complimented by the presence in Kashmir of the atheloptic trilobite Bailiella, which is characteristic of deeper waters. Faunas from Kashmir, Zanskar and Spiti, which lie within the Tethyan belt of the Indian Himalaya, share closest affinity with those described from north China, north Vietnam and south China. They also show affinity with faunas from Iran. This pattern is consistent with recent paleogeographic reconstructions which place these regions in close proximity and at similar latitudes. Most of the Cambrian within the Tethyan Himalaya is of middle Middle Cambrian age.The recognition of developmental flexibility as a general characteristic of Cambrian trilobites suggests many groups may be taxonomically over-split. Over-splitting may have lead to widespread over-estimation of faunal provinciality during Cambrian times.

Ordovician graptolite faunal compositions between the Laurentia and Baltica margins of the Iapetus Ocean differ considerably in the upper Darriwilian (Da 3 – Da 4; upper Middle Ordovician). Detailed investigation of a number of sections in the Table Head and Goose Tickle groups in western Newfoundland and the Elnes Formation of Norway provides important new faunal data for the interval from the Holmograptus lentus Biozone to the Dicellograptus vagus Biozone. The Nicholsonograptus fasciculatus and Pterograptus elegans biozones are introduced for the Table Head and Goose Tickle groups and can be recognized widely in North America. The characteristic, but poorly correlatable, shallow-water endemic faunas of the platform regions (Atlantic and Pacific faunal realms) grade into the cosmopolitan oceanic graptolite faunas (isograptid biofacies) and provide a means to precisely correlate cold-water and warm-water endemic graptolite faunas through transitional zones. The faunal differences between western Newfoundland and Scandinavia are less pronounced than hitherto assumed, and many faunal elements can now be recognized in both regions, allowing for a more precise biostratigraphic correlation. The paleobiogeographic differentiation of both regions has been based on few, but usually extremely common faunal elements, masking the presence of important biostratigraphic marker species.

AbstractThe Middle Jurassic – Early Cretaceous period witnessed the emergence of some major representatives of modern continental vertebrate groups (stem lissamphibians, squamates, therian mammals and birds) and angiosperms, at a time when fragmentation of Pangaea was underway. The successive Moroccan microvertebrate faunas of Ksar Metlili (?Berriasian) and Guelb el Ahmar (Bathonian) from the Anoual Syncline significantly improve our poor knowledge of Gondwanan and especially African palaeobiodiversity at this time. They are among the richest known from the Mesozoic of Gondwana, and are well placed in northwestern Africa to record faunal interchanges with Laurasia. Here we focus on the Ksar Metlili fauna, first documented in the 1980s and most recently resampled in 2010, which produced 24 541 microremains representing 47 species of 8 main groups (Chondrichthyes, Actinopterygii, Sarcopterygii, Lissamphibia, Lepidosauromorpha, Testudinata, Archosauromorpha and Synapsida). It includes remarkable taxa: the oldest stem boreosphenidan mammals from Gondwana, probably some of the last non-mammaliaform cynodonts, a basal ornithischian, possibly freshwater teleosaurid crocodylomorphs, and some of the rare occurrences of choristoderes and albanerpetontids in Gondwana. Comparison of the Ksar Metlili fauna with that of Guimarota (Kimmeridgian, Portugal) further provides evidence of numerous shared taxa of Laurasian affinities, in contrast to the occurrence of few taxa with Gondwanan affinities. This suggests complex palaeobiogeographical relationships – implying both vicariance and dispersal events – of North Africa within Gondwana at the Jurassic–Cretaceous transition. Finally, the faunal similarities with the Guelb el Ahmar fauna question the Cretaceous age of the Ksar Metlili fauna, suggesting an alternative possible Late Jurassic age.

The rich myrmecofauna in Bulgaria, comprising about 170 species, constitutes favorable settings for a diverse associated fauna. An attempt to summarize the fragmented faunal data on this ecological group in Bulgaria, together with inclusion of new data, has resulted in a comprehensive list of 121 beetle species from 14 families, obligate or facultative ant related. The extent of current knowledge on the various beetle families, host specificity, the nature of relations between guests and their ant hosts, and the regional characteristics of the myrmecophilous fauna are discussed.

Macroevolutionary change from the Middle to the Late Paleozoic crinoid fauna was not the result of mass extinction. The presumption that the decline of the middle Paleozoic crinoid fauna was from a single mass extinction event was tested using seriation, multidimensional scaling (MDS), binomial analysis, and bootstrapping simulations on a data set which is a comprehensive revision of old faunal lists. The data for these analyses were based on temporal distributions of 214 species from 69 late Osagean and early Meramecian localities from the midcontinental United States. The time under consideration is subdivided into seven informal intervals using MDS in conjunction with biostratigraphy. Seriation of species ranges into these intervals results in a gradual pattern of faunal turnover, and sampling bias can be eliminated as a cause for this more gradual pattern. MDS analysis of the crinoid range data is similar to MDS simulations using data with continuous, monotonic species turnover and dissimilar to a simulated mass extinction. Binomial analysis and bootstrapping demonstrate that the observed number of extinctions at the putative extinction boundary were not unusually high. All methods agree that extinctions throughout this time were high but spanned several time intervals and that rapid, monotonic faunal turnover describes the data better than mass extinction. Macroevolutionary processes other than mass extinction and microevolutionary processes must have dictated the character and composition of this remarkable faunal transition among the Crinoidea.

Abstract Elasmobranch remains are quite common in Miocene deposits and were the subject of numerous studies since the middle of the nineteenth century. Nevertheless, the taxonomic diversity of the Marine Molasse sharks, rays and skates is still largely unknown. Here, we describe 37 taxa from the lower Miocene of the Molasse Basin: 21 taxa could be identified at species level, whereas 15 taxa could only be assigned to genus and one taxon is left as order incertae sedis. The material was collected from deposits of the Auwiesholz Member of the Achen Formation (middle Burdigalian, middle Ottnangian age, ca. 17.8 Ma) exposed near Simssee, Upper Bavaria. This faunal assemblage is a mixture of shallow marine, near-coastal, pelagic and deep-water taxa. The fauna from Simssee displays different biogeographic dynamics at local and regional scales, possibly related to the intense climatic, oceanographic and tectonic events that occurred during the Eggenburgian–Ottnangian stages. The faunal relationships of the early Miocene chondrichthyan faunas from the Mediterranean Sea and Paratethys with others regions are established on the basis of qualitative (presence/absence) data. The beta diversity (Sørensen–Dice coefficient) of the Miocene Molasse elasmobranchs was used to characterize the taxonomic differentiation between localities and regions. According to our results, the fauna from Simssee shows close similarities with those from Switzerland, Austria, France and northern Germany. Faunal similarities and differences are mainly related to tectonic events and oceanographic variables (i.e. migration through seaway passages) or might represent collecting biases.

A field survey for the invertebrate fauna conducted in the Ma River, Thanh Hoa province in 2013. The research applied multivariable analysis performed by the Primer v.6 software, such as CLUSTER, one-way ANOSIM, BEST and DIVERSE. The results showed a list of 138 aquatic invertebrate species. Of these, most were freshwater wide-distributing species coupled with others characterized for brackish and marine waters. The biodiversity status was quite high compared to several other rivers in the North of Vietnam. The list contained many economic-valued species and 2 of these were listed in the Red Data Book of Vietnam. The aquatic invertebrates showed a significant relation to the two different combinations of physiochemical factors for zooplanktons and zoobenthos, respectively. The values of the species number, abundance and Shannon-Weiner index for both of zooplanktons and zoobenthos showed a curved trend from the upper river segments to lower river segments. These figures for zooplanktons peaked in the middle river segments, whereas the numbers for zoobenthos achieved the highest numbers in the estuaries. The species composition of the estuaries differentiated significantly from that of other freshwater habitatsNăm 2013 đã tiến hành một đợt điều tra khu hệ động vật không xương sống sông Mã, tỉnh Thanh Hóa.

Nel presente lavoro di tesi verrà analizzato il contesto del monitoraggio faunistico, nello specifico della fauna ittica, introducendo concetti moderni quali IoT e Big Data. In seguito sarà descritta la progettazione e l’implementazione di un applicativo web specifico per il monitoraggio della fauna ittica delle acque interne superficiali, sviluppato in collaborazione con i ricercatori del BIGEA di Bologna.
Analizzando in partenza il database esistente è stato possibile coglierne le ridondanze e le incongruenze presenti, per poi strutturare un nuovo database adatto a rappresentare i dati quotidianamente manipolati dai ricercatori. E` stata successivamente definita la struttura client-server di un moderno applicativo web a cui è seguita l’implementazione delle funzionalità legate alla gestione delle stazioni di campionamento. Il lavoro così ottenuto si rivela infine pronto per successive implementazioni future, che porteranno ad un completo aggiornamento delle metodologie ora utilizzate per la gestione dei dati faunistici ittici da parte dei ricercatori del BIGEA di Bologna. Il nuovo modello ER proposto infatti pone le basi per implementare la registrazione e il monitoraggio dei dati relativi ai campionamenti effettuati, dallo studio della vegetazione fino al singolo pesce analizzato.

Parmi les grandes questions qui agitent le monde scientifique actuellement, la régression continue de la biodiversité à l’échelle planétaire soulève un problème majeur qui pose autant d'inquiétude que les changements climatiques. La disparition des espèces suite aux perturbations portées aux écosystèmes ou par pression directe est d'ores et déjà une réalité indéniable. La zone sahélo-saharienne fait partie des régions arides très touchées par ce phénomène d’érosion de la diversité biologique. D’ores et déjà plusieurs espèces d’antilopes présentent un statut mondial précaire ou sont mêmes éteintes. Le guépard du Sahara, prédateur potentiel de ces dernières, est devenu un taxon extrêmement rare, en partie à cause de l’effondrement des populations de ses proies. Nos recherches sont en grande partie centrées sur la réintroduction de l'oryx algazelle et de la gazelle Mohor au Ferlo sénégalais, elles portent également dans une première partie sur l'état de déclin alarmant de la grande faune sahélo-saharienne en considérant le statut d'un échantillon type formé par six taxons. Il s'agit d'un oiseau, l'autruche à cou rouge (Struthio camelus camelus) et de cinq mammifères à savoir le bubale buselaphe (Alcelaphus buselaphus buselaphus), l'addax (Addax nasomaculatus), la gazelle dama (Gazella dama), l'oryx algazelle (Oryx dammah) et le guépard (Acinonyx jubatus). La deuxième partie traite les aspects théoriques et pratiques de la question de la réintroduction et d'une manière sommaire la problématique des petites populations et des phénomènes connexes de consanguinité. Sous le volet de la troisième partie, nous nous sommes intéressés aux premiers résultats de l'état de restauration de l'habitat dans lequel s'est effectuée l'opération de réintroduction de l'oryx algazelle et la gazelle Mohor, deux antilopes éteintes dans la nature. On a utilisé pour suivre l’évolution des habitats en voie de restauration dans l’enclos un support cartographique provenant de l'interprétation de deux images satellite prises à deux ans d'intervalle. L'utilisation de l'habitat par les animaux réimplantés est analysée pour les deux saisons qui caractérisent la zone sahélienne et les premiers éléments de la dynamique des populations des deux antilopes sont examinés à la lumière de l'évolution des effectifs pendant les trois premières années. En guise de recommandation, la poursuite du suivi de l’évolution de l'espace et des antilopes réintroduites est proposée pour une meilleure gestion des prochaines opérations de repeuplementAmong the main topics that are currently agitating scientists, the unceasing biodiversity decline on a planetary scale raises a major problem which is sparking off as much concern as the global warming. Species disappearance as a result of ecosystem disturbances or from direct pressure on taxa is an undeniable reality. The Sahelo-saharan zone is part of the arid areas which have been badly affected by biological diversity erosion. Several species of antelopes are showing a precarious status or are even extinct. The Saharan cheetah, a potential predator of those antelopes, is now a too rare taxon, partly due to the collapse of its prey populations. Our researches are focused on the reintroduction of the Scimitar-horned oryx and the Mohor gazelle in the Senegalese Ferlo. In the first part the severe decline of the large Sahelo-Saharan fauna is presented, considering the status of a representative sample of six taxa : one bird, the red-necked ostrich (Struthio camelus camelus), and five mammals, the Northern hartebeest (Alcelaphus buselaphus buselaphus), the Addax (Addax nasomaculatus), the Dama gazelle (Gazella dama), the Scimitar-horned oryx (Oryx dammah) and the cheetah (Acinonyx jubatus). In the second part, we deal with the theoretical and practical aspects of species reintroduction and with small populations’ issues and the inbreeding related consequences. In the third part, we were interested in the first restoration outcomes of the habitat in which was carried out the reintroduction operation of the Scimitar-horned oryx and the Mohor gazelle, which have both disappeared in the natural environment. Habitat evolution monitoring has been studied by using a cartographic support coming from the interpretation of two satellite images taken at a two years interval. The use of the habitat by the reintroduced animals has been analysed for the two seasons characterizing the sahelian area and eventually the first data on the two antelopes population dynamics were examined in the light of the increasing size of both populations during the first three years. For a better management of next reintroduction operations, the monitoring of the habitat and the population dynamics of the reintroduced antelopes are recommended

The international trade in wildlife products is an extremely profitable industry, and is linked to many environmental, social, economic and political problems. The Convention on the International Trade of Endangered Species of Wild Fauna and Flora (CITES) is a non-self-executing multilateral treaty providing a framework for the international trade in wild animals and plants. Unfortunately, CITES wildlife trade data is not always accurate. Export and import trade records between nations rarely align and frequently contain data discrepancies. This study analyzed CITES wildlife trade records for Appendix I and II species exported out of Africa between the years 2003 to 2012 to determine the frequency and types of discrepancies, and to identify nations and species particularly prone to record discrepancies. This study also attempted to profile countries with high and low documentation discrepancy rates based on annual precipitation, proportion of land covered by forest, length of coastline, GEF Benefits Index for Biodiversity, proportion of country designated as protected area, proportion of roads that are paved, number of international airplane departures, national population size, life expectancy, Gini Index, Gross Domestic Product, Mo Ibrahim Index of African Governance and unemployment rate.

CAPEs
O objetivo principal da presente tese consistiu em agregar informações ao conhecimento sobre o tubarão galha-branca oceânico (Carcharhinus longimanus), principalmente no que se refere à sua distribuição, índices de abundância e preferências de habitat. Apesar de ser uma espécie muito capturada na pesca oceânica de atuns afins, informações acerca destes aspectos ecológicos são escassas e até mesmo ausentes na literatura relacionada à espécie. A tese é apresentada como um conjunto de capítulos autônomos, representando artigos científicos individuais. No primeiro capítulo-artigo foram discutidos os possíveis efeitos de medidas de manejo restritivas, implementadas recentemente por Organizações Regionais da Pesca Atuneira e que incluem algumas espécies de tubarões oceânicos. Medidas restritivas isoladas terão pouco impacto na redução da mortalidade de tubarões oceânicos. Um conjunto de medidas mitigadoras integradas será mais eficaz na conservação e recuperação das populações dessas espécies. No segundo capítulo-artigo foram analisados dados de captura e esforço de 14.835 lançamentos de espinhel pelágico realizados por embarcações arrendadas da frota atuneira brasileira, nos anos de 2004 a 2010. A CPUE nominal exibiu uma tendência de aumento gradual ao longo dos anos, variando de 0,04 em 2004 para 0,15 em 2010. A CPUE foi padronizada através de uma abordagem delta-GLM, entretanto, o índice de abundância padronizado não diferiu significativamente da CPUE nominal. Os modelos indicaram que as capturas de tubarões galha-branca são maiores para a estratégia de pesca espanhola, que se caracteriza pela utilização de anzóis em profundidades mais rasas. No terceiro capítulo-artigo, a interação entre tubarões galha-branca e a pesca de rede de cerco nos Oceanos Atlântico e Índico foi analisada, com o objetivo de investigar o potencial da utilização do banco de dados dessa pescaria para derivar índices de abundância e determinar tendências populacionais para a espécie. Dados de observadores de bordo da frota francesa combinados com dados históricos da União Soviética foram utilizados na análise. A série temporal combinada incluiu os anos entre 1986 e 2014. No Oceano Atlântico não foi possível determinar uma tendência populacional, uma vez que o índice de ocorrência foi muito baixo e não variou significativamente com o tempo. No Oceano Índico foi observada uma mudança bem-marcada no índice de ocorrência, oscilando em torno de 20% entre meados dos anos 80 e 90 e caindo para menos de 10% a partir de 2005. No quarto capítulo-artigo, a vulnerabilidade do tubarão galha-branca à pesca de espinhel pelágico foi avaliada utilizando dados dependentes e independentes da pesca. Os dados dependentes incluíram informações de diários de bordo (1999- 2011) e observadores embarcados (2004 a 2010), num total de 65.277 lançamentos de espinhel. Os dados independentes foram obtidos a partir de 8 tubarões marcados com marcas do tipo “pop-up satellite archival tag” na área onde a frota de espinhel operou. Locais de marcação e desprendimento das marcas foram relativamente próximos uns dos outros. Entretanto, os indivíduos marcados tenderam a viajar longas distâncias antes de retornar para a área de marcação. Foi observado um certo grau de filopatria à área. “Hotspots” de alta utilização dos tubarões marcados correspondeu à área sob forte pressão pesqueira. Todos os tubarões exibiram uma forte preferência por águas quentes e rasas da camada de mistura, gastando, em média, mais de 70% do tempo acima da termoclina e 95% acima de 120 m. Esse resultado justifica a maior capturabilidade da espécie em espinheis mais rasos. No quinto e último capítuloartigo, os movimentos verticais dos tubarões marcados foram analisados em detalhe. Apesar da distribuição vertical restrita, os dados indicaram que o tubarão galha-branca apresenta padrões de movimento complexos, incluindo padrões de migrações circadianas distintos e mergulhos profundos. O padrão circadiano mais frequentemente observado é caracterizado de um deslocamento à superfície durante o nascer do sol e uma tendência a permanecer em profundidades mais baixas durante o dia. Os movimentos verticais também foram influenciados pela temperatura da superfície do mar, o que pode indicar a ocorrência de termoregulação para espécie. A integração dos resultados de cada capítuloartigo proporcionou boas perspectivas para o desenvolvimento de medidas de mitigação. A evidência em relação à preferência do tubarão galha-branca por águas quentes e rasas é sólida, indicando que a remoção dos anzóis rasos do espinhel pode ser proposta para reduzir a captura incidental da espécie. O fato de variações na CPUE já terem sido observadas, sugere que esta pode ser uma medida eficaz. O comportamento filopátrico observado para o OCS também indica que a espécie pode se beneficiar com a criação de áreas marinhas protegidas.
The ultimate goal of this thesis was to generate knowledge regarding the ecology of the oceanic whitetip shark (Carcharhinus longimanus) and contribute for an ecosystem-based fishery management. The work focuses on the interactions between tuna fisheries and the species and its habitat preferences. Despite being frequently caught on high-sea fisheries, there are wide knowledge gaps regarding the ecology of the oceanic whitetip shark. The thesis is presented as a set of selfcontained standalone chapters, constructed as individual research articles. The first article-chapter provides a discussion concerning pelagic sharks and the recent species-specific banning measures implemented by Regional Fishery Management Organizations (RFMOs) in charge of tuna fisheries. It is unlikely that banning measures alone can reduce the high level of fishing mortality and recover pelagic shark’s depleted populations. Managers should be fully aware that the development and implementation of mitigation measures are critical for a more effective conservation strategy. In the second article-chapter, catch and effort data from 14,835 longline sets conducted by foreign tuna longline vessels chartered by Brazil, from 2004 to 2010, were analyzed. The nominal catch per unit of effort (CPUE) exhibited a gradual increase, varying from 0.04 sharks/1000 hooks in 2004 to 0.15 in 2010. A CPUE standardization was performed using a delta-GLM approach, but the standardized index of abundance did not differ significantly from the nominal CPUE. The models indicated that the catches of oceanic whitetip sharks are higher for the Spanish fishing strategy, which is characterized by the deployment of hooks at shallower depths. In the third article-chapter, the interaction between oceanic whitetip sharks and the purse seine fishery in the eastern Atlantic and western Indian oceans was analyzed, in order to investigate the potential of using this fishery’s database to derive abundance indexes and determine population trends for the species. Observer data from the French purse seine fleet combined with a historic database from the Soviet Union were used in the analyses. The combined time series spanned from 1986 to 2014. The occurrence index was very low for Atlantic Ocean and no marked temporal trend was observed. For the Indian Ocean a well-marked change on the occurrence index was observed, fluctuating around 20% from mid 80’s to mid 90’s and dropping to less than 10% as from 2005. In the fourth article-chapter, a combination of fisheries dependent and independent data was used to assess the vulnerability of the oceanic whitetip shark to pelagic longline fisheries. Fisheries dependent data included information from logbooks (from 1999 to 2011) and onboard observers (2004 to 2010), totaling 65,277 pelagic longline sets. Fisheries independent data were obtained from 8 oceanic whitetip sharks tagged with popup satellite archival tags in the area where longline fleet operated. Tagging and pop-up sites were relatively close to each other, although individuals tended to travel long distances before returning to the tagging area. Some degree of philopatry was observed. High utilization hotspots of tagged sharks fell inside the area under strongest fishing pressure. All sharks exhibited a strong preference for the warm and shallow waters of the mixed layer, spending on average more than 70% of the time above the thermocline and 95% above 120 m. This result explains the higher catchability of the species on shallow longline gear. In the fifth and last article-chapter, the vertical movements of tagged oceanic whitetip sharks were analyzed in detail. Despite its restricted vertical distribution, the analyses reveled that oceanic whitetips perform complex movement patterns, including distinct diel patterns and deep diving behavior. A correlation between vertical movements and sea surface temperature was also observed, suggesting the occurrence of thermoregulation for the species. The combined results of each article-chapter have provided good insights towards the development of mitigation measures. The evidence regarding oceanic whitetip shark’s preference for warm and shallow waters is solid and this information suggests that the removal of the shallow hooks from the longline gear could be proposed as a technique to reduce OCS bycatch. The fact that CPUE variations were already observed suggests that this might be an effective measure. The philopatric behavior observed for the OCS also indicates that the species could benefit from time-area closure measures.

The methodological and theoretical considerations that must be addressed when excavating the traditional longhouses of the First Nation peoples who lived in the Pacific Northwest region are the foci of this thesis. The large amount of faunal data contained within the remains of houses require the use of explicit, justifiable sampling strategies; however, the methods used to sample these dwellings are not generally a central research focus. A sampling simulation of faunal data recovered from the excavation of numerous houses from the village site of Ozette is the empirical basis of this research. Specifically, the effects of sample size and sample method on richness, relative abundance and the interpretation of status using faunal data are investigated. The results are of heuristic value for future household archaeology on the Northwest Coast and suggest alternative sampling methods which attempt to cope with the labour-intensive research generally required for shell-midden archaeology.

Nombe rockshelter was excavated by M-J. Mountain between 1971 and 1980. Human activity is first documented at the site at about 25,000 bp and continues through to the present. Four extinct Pleistocene herbivores, Protemnodon nombe,Protemnodon tumbuna,Dendrolagus noibano and a diprotodontid,occur in late Pleistocene strata together with human artefacts. Large quantities of animal bone were recovered and the analysis of these supplies the major data for the research.
Three main issues are addressed:
1. The nature of the relationship between the early humans and their environment through the period that covers the late glacial maximum at about 18,000 bp.
2. The relationship between humans and the extinct species, including the thylacine, Thylacinus cynocephalus, which was a major predator at the site, contributing bone to the deposits during the Pleistocene.
3.The use of faunal evidence as an indicator of economic and subsistence activities as well as local environmental changes.
The data show that the human activity during the late Pleistocene at Nombe was sporadic over the period from about 25,000 bp to about 15,000 bp. Hunters were probably targeting the large herbivores living in high altitude forest and other species adapted to high altitude cold environments. Humans and large herbivores coexisted for about 10,000 years before the animals disappeared from the record. This coexistence does not suggest a rapid demise through human overkill.
Palynological evidence suggests that people were deliberately firing small patches of highland forest as early as 30,000 bp. Such clearing could have been used to promote forest-edge plants especially Pandanus, which has rich oily nuts. These small clearings could also have been used as an aid to hunting.
By the end of the Pleistocene, human hunting had switched to emphasise medium and smaller forest animals, especially fruitbats, macropodids, phalangers and possums. Bat hunting was especially important at Nombe, which is in a limestone area with many caves.
In the early Holocene the temperatures rose and sub-alpine grasslands were greatly reduced as forest spread to higher altitudes. The archaeological evidence shows that more sites were occupied by 10,000 bp than before and the faunal
data at Nombe indicate a steep rise in the grassland wallaby, Thylogale brunii. This species adapts easily to forest disturbance and may indicate that forest clearance was increasing in the locality. The early Holocene was the period of intense human settlement of the site.
The faunal analysis employed in this study is designed to test the broad questions about human:...environment relationships rather than to supply detailed information about the size and sex representation in the species present. Species are often dealt with as a group and no individual bone measurements have been taken. The computer database has been designed to produce a flexible data set that can easily be adapted to taxonomic change. The success of the approach suggests that faunal evidence can be a sensitive indicator of environmental change and can be used to examine human predation strategies and changes in economic subsistence.

Detailed research into marsupial behavioural ecology and modelling of past Aboriginal exploitation of terrestrial fauna has been scarce. Poor bone preservation is one limiting factor in Australian archaeological sites, but so has been the lack of research concerning the ecology and physiology of Australia’s endemic fauna. Much research has focused on marine and fresh-water shell-fish found in coastal and inland midden sites. Detailed studies into areas such as seasonality of past human occupation and nutritional returns from terrestrial prey species have not had the same attention. This chapter reviews the current level of published Australian research into two aspects of faunal studies, seasonality and nutrition. It describes the patterns from well-researched faunal data excavated from the Ice Age sites in southwest Tasmania. Concentration is on the vertebrate fauna found in seven limestone cave sites to examine any temporal changes to seasonal butchery and identify any differences between seasonally occupied sites.

Images, texts, and bones shed light on the place of animals in the later Bronze Age societies of southern Greece. Iconography offers an idealized vision of encounters with dangerous, exotic, and mythical beasts, of travel in elaborate horse-drawn chariots, and of ceremonial slaughter of bulls. Reality, even for the elite and as revealed by textual and faunal evidence, was more mundane: killing and consumption of sheep, goats, and pigs more than lions, deer, and bulls; and dependence, to finance a palatial lifestyle, on draught oxen for grain production and wool-sheep for exchangeable prestige textiles. Linear B texts describe aspects of animal management of interest to the Mycenaean palaces, while faunal data make clear how restricted were these interests. Faunal and ceramic data highlight the importance of commensality throughout the Neolithic and Bronze Age, and the shift from overtly egalitarian gatherings in the Neolithic to ostentatiously inegalitarian in the Bronze Age.

The American Southwest has an unusually rich record of pre-colonial hunting. Projectile points reflect technological change, and can serve as chronological and social markers, but dry preservation also allows direct study of bow and atlatl propulsion systems. Other organic artifacts, including nets, snares, and clubs, reflect the importance of mostly small game in pre-colonial diets and society. Faunal remains, coprolites, and iconography enlarge the record, and continuities with descendant cultures allow unusually good interpretation of hunting practices. Using archaeological data and ethnographic parallels, this chapter discusses the various intentional and opportunistic hunting technologies used through time to procure faunal resources.

Evidence is considered here for the utilization of domestic farm and companion animals for products other than meat, for example goat horns and calf and cat skins. Selection pressures driving changes in the stature of cattle are suggested to reflect environmental changes from the Medieval Warm Period to the Little Ice Age. An example of catastrophic cattle mortality is examined with regard to the difficulty of establishing the causative effect, the sex ratio of the bodies, and the impact on the manorial farm. Routine disposal of inedible carrion is discussed with regard to urban disposal of horse bones. Constraints on livestock husbandry and the survival of faunal evidence in the uplands of Wales, northern England, and Scotland are used to demonstrate the effect of legal and commercial considerations on the Scottish data.

In the ninth century AD, settlers from the heartland of the Wari Empire founded Quilcapampa, a short-lived site overlooking the Sihuas River in southern Peru. The contributors to this volume present excavation and survey data from in and around Quilcapampa that challenge long-held models of both Wari statecraft and the mechanisms that engendered the widespread societal changes of the era. Quilcapampa and other peripheral Wari settlements have generally been seen as local administrative centers that siphoned resources from conquered regions to the Wari capital. This volume demonstrates that Quilcapampa was likely founded not by Wari officials but by families looking for a new home amid the turmoil caused by increasing Wari political centralization. Botanical, faunal, ceramic, lithic, and other data sets are used to reconstruct lifeways at the site and show how the settlers interacted with others locally and across greater distances. Featuring extensive illustrations in the print edition and multimedia components in the digital edition, this book offers an abundance of archaeological data on the site as well as new theoretical considerations of Wari expansion, laying the foundation for a better understanding of how Andean political economy and social complexity changed over time.

This chapter considers the significance of the Ediacaran Fauna. Until the late 1980s, the Ediacaran Fauna were usually thought to represent ancient, primitive animal forms. Debate was sparked when leading paleontologist Dolf Seilacher from Tubingen, Germany, reinterpreted these fossils as something completely different. He argued that, instead of animals, they were long-extinct varieties of living organisms, a result of failed lineages with no successors. The rocks on the Avalon Peninsula of southeastern Newfoundland house the oldest known representatives of the Ediacaran Fauna. These so-called rangeomorphs date back to 575 million ago and appear relatively soon after the end of the Gaskiers glaciation some 580 million years ago. Evidence suggests that Ediacaran Fauna of the Avalon Peninsula emerged into an ocean undergoing oxygenation.

More than 300 species of Australian native animals — mammals, birds, reptiles and amphibians — use tree hollows, but there has never been a complete inventory of them. Many of these species are threatened, or are in decline, because of land-use practices such as grazing, timber production and firewood collection.
All forest management agencies in Australia attempt to reduce the impact of logging on hollow-dependent fauna, but the nature of our eucalypt forests presents a considerable challenge. In some cases, tree hollows suitable for vertebrate fauna may take up to 250 years to develop, which makes recruiting and perpetuating this resource very difficult within the typical cycle of human-induced disturbance regimes.
Tree Hollows and Wildlife Conservation in Australia is the first comprehensive account of the hollow-dependent fauna of Australia and introduces a considerable amount of new data on this subject. It not only presents a review and analysis of the literature, but also provides practical approaches for land management.

AbstractThe unique diversity of the world’s highest flora and fauna is a sacred landscape for the resident Sherpa communities, but climate change has been casting a threatening shadow over World Heritage Sagarmatha (Mt Everest) National Park (SNP) for years, causing rapid and pronounced impacts. Tourism is a key driver to the local economy but is exacerbating the impacts of climate change. Through extensive community and individual surveys in major villages, combined with a wealth of data from other studies, we focus on how the impacts of climate change and tourism development can be countered by measures at the local level. We identified two sources of conflict that need to be addressed: (1) conflict between tourism businesses and park management and (2) a lack of awareness of the need for an overarching conservation strategy among residents and stakeholders. To solve these issues, site management needs considerable enforcement and support from the State Party.

AbstractThe known arthropod vector species on the Gulf of Guinea islands belong to orders Diptera and Ixodida. Among the Diptera, the family Culicidae (mosquitoes) has the most species, 34 (6 endemic), Ceratopogonidae has 13 (all in the genus Culicoides), Tabanidae has 6, and Simuliidae has 3 (1 endemic). Ixodida has only 4 species. Most vector species and associated diseases are shared with mainland Africa. Some of these include (1) the human malaria vector Anopheles coluzzii, (2) yellow fever and dengue vector Aedes aegypti, and (3) the spotted fever group rickettsiae and Q fever vector Amblyomma spp. However, there is a considerable lack of information on the natural cycles of many vector-borne diseases that might impact local fauna, for which there may be some endemic pathogen lineages. Increased trade by air and sea should compel authorities to remain vigilant, to keep unwanted vectors and diseases at bay. Entomological diversity data remains scarce for Annobón and for the forested interior of the islands, where future sampling efforts may uncover new endemic species.

The analytical review was made on the basis of literature data, and archive material, and personal studies of the parasitofauna, which were carried out on the Azov-Black Sea branch of FGBNU "VNIRO" ("AzNIIRH"). The object of the research is parasitic organisms, which parasitize on the Black Sea Turbot - Kalkan. The results of the research prove that the parasitofauna of mature, wild flounder off the southern coast of the Crimean peninsula is represented by 4 species. No parasites are detected in juvenile flounder obtained in an industrial way in the conditions of the research base "Zavetnoe" of the Kerch department of the Azov-Black Sea branch of FGBNU "VNIRO" ("AzNIIRKh").

A fundamental responsibility of the National Park Service is to ensure that park resources are preserved, protected, and managed in consideration of the resources themselves and for the benefit and enjoyment by the public. Through the inventory, monitoring, and study of park resources, we gain a greater understanding of the scope, significance, distribution, and management issues associated with these resources and their use. This baseline of natural resource information is available to inform park managers, scientists, stakeholders, and the public about the conditions of these resources and the factors or activities which may threaten or influence their stability. There are several different categories of geologic or stratigraphic units (supergroup, group, formation, member, bed) which represent a hierarchical system of classification. The mapping of stratigraphic units involves the evaluation of lithologies, bedding properties, thickness, geographic distribution, and other factors. If a new mappable geologic unit is identified, it may be described and named through a rigorously defined process that is standardized and codified by the professional geologic community (North American Commission on Stratigraphic Nomenclature 2005). In most instances when a new geologic unit such as a formation is described and named in the scientific literature, a specific and well-exposed section of the unit is designated as the type section or type locality (see Definitions). The type section is an important reference section for a named geologic unit which presents a relatively complete and representative profile for this unit. The type or reference section is important both historically and scientifically, and should be recorded such that other researchers may evaluate it in the future. Therefore, this inventory of geologic type sections in NPS areas is an important effort in documenting these locations in order that NPS staff recognize and protect these areas for future studies. The documentation of all geologic type sections throughout the 423 units of the NPS is an ambitious undertaking. The strategy for this project is to select a subset of parks to begin research for the occurrence of geologic type sections within particular parks. The focus adopted for completing the baseline inventories throughout the NPS was centered on the 32 inventory and monitoring networks (I&M) established during the late 1990s. The I&M networks are clusters of parks within a defined geographic area based on the ecoregions of North America (Fenneman 1946; Bailey 1976; Omernik 1987). These networks share similar physical resources (geology, hydrology, climate), biological resources (flora, fauna), and ecological characteristics. Specialists familiar with the resources and ecological parameters of the network, and associated parks, work with park staff to support network level activities (inventory, monitoring, research, data management). Adopting a network-based approach to inventories worked well when the NPS undertook paleontological resource inventories for the 32 I&M networks. The network approach is also being applied to the inventory for the geologic type sections in the NPS. The planning team from the NPS Geologic Resources Division who proposed and designed this inventory selected the Greater Yellowstone Inventory and Monitoring Network (GRYN) as the pilot network for initiating this project. Through the research undertaken to identify the geologic type sections within the parks of the GRYN, methodologies for data mining and reporting on these resources was established. Methodologies and reporting adopted for the GRYN have been used in the development of this type section inventory for the Chihuahuan Desert Inventory & Monitoring Network. The goal of this project is to consolidate information pertaining to geologic type sections which occur within NPS-administered areas, in order that this information is available throughout the NPS...
