1. Roadkilled mammals in the northern Amazon region and comparisons with roadways in other regions of Brazil
RESUMO As rodovias e o fluxo de veículos contribuem para os processos de fragmentação da paisagem e alteração do habitat natural, representando ameaça para conservação das espécies em diversos biomas. Este estudo avalia os registros de atropelamentos das espécies de mamíferos silvestres e compara este com outros 37 estudos realizados no Brasil, pa

2. Threats to and viability of the giant anteater, Myrmecophaga tridactyla (Pilosa: Myrmecophagidae), in a protected Cerrado remnant encroached by urban expansion in central Brazil
Urbanization poses a serious threat to wildlife populations inhabiting native vegetation remnants surrounded by the expanding urban and suburban sprawl. The close contact with human activities causes not only direct impacts, such as habitat loss, but also indirect negative effects, such as population isolation, roadkills and anthropogenic fires. The Parque N

3. Genética aplicada à ecologia de estradas: um estudo na estrada municipal Guilherme Scatena (São Carlos, SP) e potencial impacto na biodiversidade local.
Roads generate a large ecological impact to wildlife by raising barriers among ranges of species originally continuous and for causing road-kills. After road-killing, a morphological identification becomes impossible for the loss of diagnostic features, especially in the case of small vertebrates. Use of molecular tools for identification is an alternative t

4. Feeding habits of Molina's hog-nosed skunk, Conepatus chinga (Carnivora: Mephitidae) in the extreme south of Brazil
Feeding habits of the Molina's hog-nosed skunk, Conepatus chinga (Molina, 1782) in the extreme south of Brazil. We analyzed 60 stomachs of road-kills of C. chinga in the extreme south of Brazil. The contents revealed 808 prey parts, including invertebrates (frequency of occurrence - FO = 96.7% and relative abundance - RA = 94.7%), vertebrates (FO = 18.3% and

5. 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

6. Fauna atropelada : estimativas de mortalidade e identificação de zonas de agregação
Vehicle-wildlife collisions are considered the main human factor responsible directly for vertebrate mortality worldwide. Roadkill estimates are elementary to evaluate road impacts, but carcass removal and searcher efficiency must be considered in order to diminish estimation bias. Mitigation measures have been implemented to reduce wildlife mortality and to

7. Mammal occurrence and roadkill in two adjacent ecoregions (Atlantic Forest and Cerrado) in south-western Brazil
This paper examines the frequencies of mammal roadkill in two adjacent biogeographic ecoregions (Atlantic Forest and Cerrado) of Brazil. Mammals were recorded during a seven-year period and over 3,900 km of roads, in order to obtain data for frequencies of species in habitats (sites) and frequencies of species killed by cars on roads. Sites (n = 80) within e

8. Demografia e variação genética de Puma concolor (Linnaeus, 1771) na região nordeste do estado de São Paulo
The northeast area of São Paulo state was originally covered by cerrado and semideciduous forest, but for the last two centuries, it has experienced distinct cycles of human exploitation of its fertile soils. Despite of intensive human activities, large habitat loss and fragmentation of the native vegetation cover, pumas (Puma concolor) still inhabit remnan

9. Evolução dos índices de atropelamento de vertebrados silvestres nas rodovias do entorno da estação ecológica Águas Emendadas, DF, Brasil, e eficácia de medidas mitigadoras / Evolução dos índices de atropelamento de vertebrados silvestres nas rodovias do entorno da estação ecológica Águas Emendadas, DF, Brasil, e eficácia de medidas mitigadoras
A grande quantidade de atropelamentos de animais em rodovias que circundam áreas de Unidades de Conservação acarreta perdas financeiras e aumenta a mortandade de animais silvestres que, conforme a literatura corrente chegou, em 1996, a pelo menos 2.700 mamíferos silvestres, atropelados nas rodovias que cortam o ameaçado bioma Cerrado e atualmente é ain
