13. Desenvolvimento placentário em quatis: evolução filogenética em carnívoros? / Placental development in quati: phylogenetic evolution in carnivores?
The importance of preservation of brazilian wild species is based on knowledge of their distribution, behavior in the wild and in captivity, and the detailed description of their reproductive biology in order to perpetuate the specie. One of the main impacts of this study is the scientific details of the uterine environment versus the process of placentation

14. Mamíferos de maior porte em paisagens tropicais alteradas: seu papel em cascatas tróficas e fatores que determinam sua distribuição / Large mammals in altered tropical forest landscapes: their role in trophic cascade and factors that determine their distribution
Nesta dissertação investigamos o papel dos mamíferos em cascatas tróficas nas florestas tropicais, e os efeitos da configuração espacial e qualidade do habitat assim como das atividades humanas atuais sobre a distribuição de mamíferos de maior porte em uma paisagem rural de Mata Atlântica. No primeiro capítulo, através de uma revisão da literatu

15. Diversidade, diferenciação e biogeografia de pequenos mamíferos não-voadores na Mata Atlântica ao norte do rio São Francisco Centro de Endemismo Pernambuco / Diversity, differentiation and biogeography of non-volant small mammals of the Atlantic Forest north of São Francisco river - Pernambuco Endemism Center
The Brazilian tropical rainforests (Amazon and Atlantic Forest) present high species diversity and are currently separated by a belt of open and dry vegetation. Part of this belt is occupied by the Caatinga, where are found the Brejos de Altitude, evidence of the historical connections between the Atlantic Forest and the Amazon. The Pernambuco Endemism Cente

16. Coordinated feeding tactics of the Guiana dolphin, Sotalia guianensis (Cetacea: Delphinidae), in Ilha Grande Bay, Rio de Janeiro, Brazil
Differences in distribution, prey species, season and social learning opportunities influence the feeding tactics used by marine mammals. Here, we analyze the coordinated feeding behavior of the Guiana dolphin, Sotalia guianensis (Van Bénéden, 1864, Delphinidae) and its relation to seasonality and the presence of calves. In a total of 201 feeding bouts, we

17. Seasonal and spatial differences in feeding habits of the Neotropical otter Lontra longicaudis (Carnivora: Mustelidae) in a coastal catchment of southeastern Brazil
The diet of the Neotropical otter Lontra longicaudis (Olfers, 1818) is one of the best known aspects of its biology throughout its distribution range. However, most dietary studies have been undertaken during short time periods, making it difficult to identify temporal patterns in the feeding behavior of the species. The present study aimed to describe the d

18. Padrões espacial e temporal do atropelamento de mamíferos em uma rodovia no cerrado brasileiro
This thesis is divided into a general introduction on the issue of roads ecology and the main factors that lead to the general public and the animals roadkills, followed by a chapter that investigates if there is spatial and seasonal patterns of medium and big mammals roadkills in a road (SP-225) in northeast of São Paulo State, Brazil. The road is located

19. Biotécnicas da reprodução animal aplicadas à conservação de cervídeos.
The present work aimed to present a literature research about two deer species - Blastocerus dichotomus (llliger, 1815) - Cervo-do-pantanal and Ozotocerus bezoarticus (Linnaeus, 1758) - Veado-campeiro, due to their importance in Central Brazil. The main aspects studied were: species biology, density and populational distribution; factors related to their dec

20. Dados biológicos do morcego-vampiro diaemus youngi no Cerrado do Distrito Federal, Brasil.
RESUMO: Embora a espécie Diaemus youngi (Jentik, 1893) seja considerada por alguns autores como ocorrendo em todo o Brasil, não há registros na literatura da captura da espécie no Cerrado do Brasil Central. Aqui, reporta-se, então, o primeiro registro da espécie nessa região, em área rural do Distrito Federal. Além disso, o trabalho apresenta alguma

21. Milk composition of franciscana dolphin (Pontoporia blainvillei) from Rio Grande do Sul, southern Brazil
Milk is the only external energy source for mammals in their early stages of life. Its composition varies during lactation in baleen whales and pinnipeds, while only descriptive studies are available for odontocetes. The aim of this work was to identify the components of the milk of franciscana, Pontoporia blainvillei, from southern Brazil. Samples were manu

22. Mamíferos carnívoros e sua relação com a diversidade de hábitats no Parque Nacional dos Aparados da Serra, sul do Brasil
A survey of carnivore mammals was accomplished in Aparados da Serra National Park from February 1998 to March 2000. The park has 10,250 ha and is considered a biodiversity core area of the Atlantic Forest Biosphere Reserve in the Rio Grande do Sul State, Brazil. The landscape is characterized by relatively well preserved relicts of Araucaria angustifolia (Be

23. Dinâmica populacional e efeitos de variáveis ambientais sobre a fauna de pequenos mamíferos em um fragmento de floresta com araucária no sul do Brasil
Natural populations of small rodents fluctuate continually over time and the population dynamics of any living organism are shaped by both intrinsic and extrinsic factors. Small mammals populations can show a continuum dynamic activity, ranging from stability to regular cycles of variable amplitude. The species dynamics is also known to be influenced by the

24. Large to medium size mammals in eucalypt plantation areas at High Pranapananema and Midle Tietê river basins, São Paulo State / Mamíferos de médio e grande porte em áreas de cultivo de eucalipto das bacias do Alto Paranapanema e Médio Tietê, Estado de São Paulo
The region comprehended amid the high portion of river Paranapanema, mid portion of river Tietê and the river Sorocaba, has a long history of human influence on landscape. This influence was intensified during the past two centuries through the passage of railroads and hydroelectric dam constructions along with other modifications that had implications on l
