High Proportion of Male Faeces in Jaguar Populations
Palomares, F.; Roques, Séverine; Chávez, Cuauhtémoc; Silveira, Leandro; Keller, Claudia; Sollmann, Rahel; Prado, Denise Mello doFaeces provide relevant biological information which includes, with the application of genetic techniques, the sex and identity of individuals that defecated, thus providing potentially useful data on the behaviour and ecology of individuals, as well as the dynamics and structure of populations. This paper presents estimates of the sex ratio of different felid species (jaguar, Panthera onca; puma, Puma concolor...
Ocelot (Leopardus pardalis) density in Central Amazonia
Rocha, Daniel Gomes da; Sollmann, Rahel; Ramalho, Emiliano Esterci; Ilha, Renata; Tan, Cedric Kai WeiOcelots (Leopardus pardalis) are presumed to be the most abundant of the wild cats throughout their distribution range and to play an important role in the dynamics of sympatric small-felid populations. However, ocelot ecological information is limited, particularly for the Amazon. We conducted three camera-trap surveys during three consecutive dry seasons to estimate ocelot density in Amanã Reserve, Central Am...
Wild dogs at stake: Deforestation threatens the only Amazon endemic canid, the ...
Rocha, Daniel Gomes da; Barros Ferraz, Katia Maria Paschoaletto Micchi de; Gonçalves, Lucas P.; Tan, Cedric Kai Wei; Lemos, Frederico GemesioThe persistent high deforestation rate and fragmentation of the Amazon forests are the main threats to their biodiversity. To anticipate and mitigate these threats, it is important to understand and predict how species respond to the rapidly changing landscape. The short-eared dog Atelocynus microtis is the only Amazon-endemic canid and one of the most understudied wild dogs worldwide. We investigated short-ear...

No. of bitstreams: 0 Previous issue date: 2018-02-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Earthwatch Institute; Memphis Zoo; Species of hemoplasmas have been described worldwide, but little information is available for wild felids. Between February 2000 and January 2010, blood samples were collected from 30 jaguars (Panthera onca...
Is the free-ranging jaguar (Panthera onca) a reservoir for Cytauxzoon felis in ...

No. of bitstreams: 0 Previous issue date: 2017-06-01; Earthwatch Institute; This study investigated the occurrence of Cytauxzoon felis and Babesia spp. in free-ranging jaguars (Panthera onca), domestic dogs (Canis lupus familiaris) and domestic cats (Felis catus) from the Cerrado, Amazon and Pantanal biomes of Brazil. Blood samples were collected from 30 j...
Density of ocelots in a semiarid environment in northeastern Brazil
Penido, Gabriel; Astete, Samuel; Furtado, Mariana Malzoni; Jácomo, Anah Tereza de Almeida; Sollmann, Rahel; Torres, Natalia; Silveira, LeandroJaguatiricas possuem um papel fundamental em comunidades ecológicas como mesopredadores, afetando níveis tróficos inferiores e também outros mesopredadores. Esta espécie possui uma grande variabilidade em suas características ecológicas em toda a sua distribuição, no entanto, o conhecimento desta espécie possui lacunas em vários locais onde ela ocorre. Neste trabalho, nós apresentamos o primeiro estudo desta es...
One or two cameras per station? Monitoring jaguars and other mammals in the Amazon
Negrões, Nuno; Sollmann, Rahel; Fonseca, Carlos; Jácomo, Anah T. A.; Revilla, Eloy; Silveira, LeandroCamera trapping has become a popular technique to monitor carnivore populations due to its usefulness in estimating abundance. Nevertheless, there are a number of problems associated with study design which are motivating researchers to search for a compromise that ensures improvement of precision while being cost-effective. We have used data from a capture– recapture study in a forested area in central Brazil t...
Use of camera-trapping to estimate puma density and influencing factors in cent...
Negrões, Nuno; Sarmento, Pedro; Cruz, Joana; Eira, Catarina; Revilla, Eloy; Fonseca, Carlos; Sollmann, Rahel; Tôrres, Natália M.; Furtado, Mariana M.We used remotely triggered cameras to collect data on Puma (Puma concolor) abundance and occupancy in an area of tropical forest in Brazil where the species’ status is poorly known. To evaluate factors influencing puma occupancy we used data from 5 sampling campaigns in 3 consecutive years (2005 to 2007) and 2 seasons (wet and dry), at a state park and a private forest reserve. We estimated puma numbers and den...
