Abstract Recently, the tiger-cat species complex was split into Leopardus tigrinus and guttulus , along with other proposed schemes. We performed a detailed analysis integrating ecological modeling, biogeography, phenotype of four originally recognized subspecies— oncilla pardinoides —and presented new multidimensional niche depiction species. Species distribution models used > 1400 records from museums photographs, all checked for accuracy. Morphological data were obtained...
The Neotropical region currently harbors 8 recognized species of small cats, including the margay (Leopardus wiedii) and jaguarundi (Puma yagouaroundi). These similar-sized have broad geographic distributions commonly occur in sympatry. We constructed occurrence databases used maximum entropy (Maxent) modeling approach to develop models habitat suitability for each these species. identified environmental predictors with highest importance evaluated how they influence both wild cats....
Enterococci are ubiquitous microorganisms present in various environments and within the gastrointestinal tracts of humans other animals. Notably, fecal enterococci suitable indicators for monitoring antimicrobial resistance dissemination. Resistant bacterial strains recovered from samples wild animals can highlight important aspects environmental disturbances. In this report, we investigated susceptibility as well virulence genes isolated Pampas foxes ( Lycalopex gymnocercus ) n = 5)...
Information about resource partitioning among small cat species that live in sympatry South America is fairly incomplete. Knowledge feeding habits essential for understanding the role of these predators environment, impact on prey populations, and potential competition themselves with other carnivores. This study aimed to describe compare diet four sympatric cats grasslands southern Brazil. We analysed stomach contents 37 Geoffroy’s (Leopardus geoffroyi), 27 margays wiedii), 14 pampas...
Abstract The black-and-gold howler monkey ( Alouatta caraya ) is widely distributed in Brazil, Bolivia, Paraguay, and northeastern Argentina. Despite this wide distribution, it locally threatened some parts of its southern range by forest loss fragmentation, yellow fever outbreaks. We present 14 new localities A. occurrence the Pampa biome extending southwards approximately 100 km.
The canid genus Lycalopex comprises six recently diversified South American species whose evolutionary relationships have been remarkably challenging to resolve. We analyzed 6000 bp of mitochondrial DNA (mtDNA) from 55 individuals (L. sechurae = 4, L. culpaeus 7, L.griseus 8, L.gymnocercus 17, L.vetulus 13 and fulvipes 6), nine specimens the closely related Cerdocyon thous, Chrysocyon brachyurus Speothos venaticus, reconstruct their phylogenetic relationships, estimate support for...
Abstract Fleas are insects with a worldwide distribution that have been implicated in the transmission of several pathogens. The present study aimed to investigate presence Rickettsia spp. (Rickettsiales: Rickettsiaceae) and Bartonella (Rhizobiales: Bartonellaceae) fleas from free‐ranging crab‐eating foxes Cerdocyon thous (Linnaeus, 1766) (Carnivora: Canidae) Rio Grande do Sul, southern Brazil. were collected manually animals used for molecular detection Twenty‐nine C. sampled six...
A ocorrência de Leopardus pardalis (Linnaeus, 1758) nos campos do sul Brasil e Uruguai têm assumido caráter histórico, visto que os últimos registros são datados fim século 19 meados 20. Dentro deste contexto, a presente comunicação visa documentar um registro inédito atual L. para o interior bioma Pampa. O evento ocorreu na Estação Ecológica Taim, quando macho adulto foi registrado partir uso armadilhas fotográficas. Esta denota uma ampliação da área distribuição austral em 300 km relação...
Ocelot is a Neotropical wildcat with broad geographic distribution. The southernmost region of its distribution an ecotone zone between biomes Atlantic Forest and Pampa in Brazil. rarely seen this region, especially the Pampa, being one most endangered wildcats region. objective study to predict potential ocelots southern limit it known measure percentage protected areas coverage. We collected 24 records species state Rio Grande do Sul we modeled using seven distinct algorithms tested two...
