13. Conservação de carnívoros e a interface homem-fauna doméstica-fauna silvestre numa área fragmentada da Amazônia oriental brasileira / Carnivore conservation and the human-domestic-wildlife interface in a fragmented área of the Eastern Brazilian Amazon
A invasão humana a áreas protegidas tem sido uma fonte crônica de conflito e ameaça à conservação da vida silvestre na Amazônia Brasileira. Em paisagens fragmentadas, os riscos podem se tornar ainda maiores. Neste estudo, estes conflitos são abordados nas Zonas de Proteção de Vida Silvestre da APA do Lago de Tucuruí, na Amazônia Oriental Brasile

14. Great felids and the abundance of mesopredators in fragments of atlantic forest in São Paulo State / As onças e as abundancias de predadores intermediarios em fragmentos de mata atlantica do Estado de São Paulo
Top predators may be particularly vulnerable to local extinction in fragmented landscapes, where their disappearance can lead to higher densities of small mammalian predators, or mesopredators, and the impoverishment of lower trophic levels. This is the basis of the hypothesis of "mesopredator release?". Northern Hemisphere studies support this hypothesis. U

15. Ecology of carnivores mammals and the conservation of the Atlantic Forest in the Region of Cananeia, state of São Paulo, Brazil / Ecologia e conservação de mamiferos carnivoros de Mata Atlantica na região do compelxo estuarino lagunar de Cananeia, Estado de São Paulo
Na Floresta Atlântica, existe uma grande deficiência de informações sobre os mamíferos da ordem Carnívora, principalmente em ambientes estuarinos e insulares, assim esse estudo teve o objetivo geral de fornecer as primeiras informações sobre a comunidade de mamíferos carnívoros em três ilhas da região do Complexo Estuarino Lagunar Iguape/Cananéi

16. Comunidade de mamiferos não-voadores de um fragmento de floresta Atlantica semidecidua do municipio de Campinas, SP
The population richness, composition, abundance and density of non-volant mammals of mata Ribeirão Cachoeira forest, a 230 ha semideciduous forest fragment in the outskirts of Campinas, São Paulo, were studied between 2001 and 2003. The main objective was to evaluate the importance of this forest fragment to the local and regional conservation of the nativ

17. 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

18. Toxocara canis (Werner, 1782) eggs in the Pleistocene site of Menez-Dregan, France (300,000-500,000 years before present)
On the archaeological site of Menez-Dregan in Brittany, France, dated 300,000-500,000 years-old, paleoparasitological analysis of cave deposits led to the detection of well-preserved helminth eggs, which morphology and morphometry pointed to the diagnosis of Toxocara canis eggs, a parasite of carnivore mammals. Paleolithic remains suggested a parasitism of t

19. Ecologia alimentar de duas especies de felinos do genero Leopardus em uma floresta secundaria no sudeste do Brasil
A knowledge of the food habits of a carnivore is central to understanding many aspects of its behavior and ecology. The main objective of this study was to describe and to compare the diet of two Leopardus species, L. tigrinus (oncilla) and L. pardalis (ocelot) in a secondary forest fragment in Southeastern Brazil. The field work was carried out in the Parqu

20. Telemetria convencional e via satélite na determinação da área de vida de três espécies de carnívoros da região nordeste do Estado de São Paulo.
The main objectives of this work were to determine diet, and home range of three mammal carnivore species, which are endangered of extinction in São Paulo State: the maned wolf ((Chrysocyon brachyurus, Illiger 1815), cougar (Puma concolor, Linnaeus 1771), and ocelot (Felis pardalis, Linnaeus 1758); and to draw strategies for landscape planning in order to i

21. Dinosaurs, dragons, and dwarfs: The evolution of maximal body size
Among local faunas, the maximum body size and taxonomic affiliation of the top terrestrial vertebrate vary greatly. Does this variation reflect how food requirements differ between trophic levels (herbivores vs. carnivores) and with taxonomic affiliation (mammals and birds vs. reptiles)? We gathered data on the body size and food requirements of the top

22. Regular exposure to rabies virus and lack of symptomatic disease in Serengeti spotted hyenas
We report a previously unrecognized complexity to the ecology of rabies in wildlife. Rabies-specific virus-neutralizing antibodies in spotted hyenas, the most numerous large carnivore in the Serengeti ecosystem (Tanzania, East Africa), revealed a high frequency of exposure of 37.0% to rabies virus, and reverse transcriptase (RT) PCR demonstrated rabies

23. Isolation of infectious bovine rhinotracheitis virus from Mustelidae.
Herpesviruses isolated from either domesticated or wild carnivores should be immunologically compared with known viruses of this group which could have been included in the diet of the animal before being considered to be previously undescribed herpesviruses native to the carnivore in question.

24. Distinguishing epidemic waves from disease spillover in a wildlife population
Serengeti lions frequently experience viral outbreaks. In 1994, one-third of Serengeti lions died from canine distemper virus (CDV). Based on the limited epidemiological data available from this period, it has been unclear whether the 1994 outbreak was propagated by lion-to-lion transmission alone or involved multiple introductions from other sympatric carni
