Ecological modeling, biogeography, and phenotypic analyses setting the tiger cats’ hyperdimensional niches reveal a new species [PDF]
Recently, the tiger-cat species complex was split into Leopardus tigrinus and Leopardus guttulus, along with other proposed schemes. We performed a detailed analysis integrating ecological modeling, biogeography, and phenotype of the four originally ...

The role of melanism in oncillas on the temporal segregation of nocturnal activity [PDF]
The occurrence of coat colour polymorphisms in populations may promote the ecological success of species by permitting a wider spectrum of use of different subsets of available resources. We conducted an analysis of temporal segregation by comparing night brightness with nocturnal activity of spotted and melanistic oncillas (Leopardus tigrinus ...

This study aimed to evaluate the cryopreservation effects on the semen of oncilla (Leopardus guttulus, n = 5, 15 ejaculates) and ocelot (Leopardus pardalis, n = 5, 17 ejaculates) and compare two extenders (commercial and non-commercial extender). An andrological exam was conducted (testicle measurements and penis evaluation), including semen collection

Ocelot and oncilla spermatozoa can bind hen egg perivitelline membranes
We evaluated the capacity of ocelot and oncilla spermatozoa to bind to the perivitelline membranes (PVMs) of hen eggs in a sperm binding assay (S-PVM). In addition, a device that improves the standardization of the assay was developed. The number of sperm bound to the PVM in fresh (T1) and frozen-thawed (T2) semen from both species was compared to the ...

Comparing hair-morphology and molecular methods to identify fecal samples from Neotropical felids. [PDF]
To avoid certain problems encountered with more-traditional and invasive methods in behavioral-ecology studies of mammalian predators, such as felids, molecular approaches have been employed to identify feces found in the field.

Prey availability and temporal partitioning modulate felid coexistence in Neotropical forests. [PDF]
Carnivores have long been used as model organisms to examine mechanisms that allow coexistence among ecologically similar species. Interactions between carnivores, including competition and predation, comprise important processes regulating local ...

Six adult Leopardus tigrinus (oncilla) were studied to characterize stages of the seminiferous epithelium cycle and its relative frequency and duration, as well as morphometric parameters of the testes. Testicular fragments were obtained (incisional biopsy), embedded (glycol methacrylate), and histologic sections examined with light microscopy.

Genetic characterization of Toxoplasma gondii from Brazilian wildlife revealed abundant new genotypes [PDF]
This study aimed to isolate and genotype T. gondii from Brazilian wildlife. For this purpose, 226 samples were submitted to mice bioassay and screened by PCR based on 18S rRNA sequences. A total of 15 T.
