Could FIV zoonosis responsible of the breakdown of the pathocenosis which has reduced the European CCR5-Delta32 allele frequencies [PDF]

, 2008
Background In Europe, the north-south downhill cline frequency of the chemokine receptor CCR5 allele with a 32-bp deletion (CCR5-Δ32) raises interesting questions for evolutionary biologists.

Updating the distribution and population status of Jaguarundi, Puma yagouaroundi (É. Geoffroy, 1803) (Mammalia: Carnivora: Felidae), in the southernmost part of its distribution range [PDF]

Check List, 2017
We report new occurrence records of Puma yagouaroundi (É. Geoffroy, 1803), a widely distributed but little known Neotropical carnivore, obtained over the last 10 years in Buenos Aires province, central Argentina.

Molecular Detection of Toxoplasma gondii in Enclosures of African Primates (Papio papio and Papio hamadryas) at the Municipal Zoo of Bauru, São Paulo State, Brazil

Journal of Medical Primatology, Volume 55, Issue 3, June 2026.
ABSTRACT Toxoplasmosis is one of the most prevalent parasitic infections in animals and humans worldwide, attracting the attention of many researchers who, in recent decades, have identified the sources of Toxoplasma gondii infections to optimize the adoption of preventive measures. In previous studies, it has been found that humans are infected mainly

Genetic variability of Herpailurus yagouaroundi, Puma concolor and Panthera onca (Mammalia, Felidae) studied using Felis catus microsatellites

Genetics and Molecular Biology, 2006
We used four microsatellite loci (Fca08, Fca45, Fca77 and Fca96) from the domestic cat, Felis catus, to investigate genetic variability in specimens of Herpailurus yagouaroundi (jaguarundi, otter cat, eyra), Puma concolor (cougar, mountain lion, puma ...

Seasonal dynamics of terrestrial vertebrate abundance between Amazonian flooded and unflooded forests [PDF]

, 2018
The flood pulse is the main factor structuring and differentiating the ecological communities of Amazonian unflooded (terra firme) and seasonally-flooded (várzea) forests as they require unique adaptations to survive the prolonged annual floods ...

Monkey Meltdowns: Do Tantrums Influence Maternal Investment in Bearded Capuchin Monkeys?

Developmental Psychobiology, Volume 68, Issue 3, May 2026.
ABSTRACT Tantrums are widely discussed in human development literature and are typically defined as displays of frustration or anger. In behavioral ecology, they are hypothesized to function as a strategy for securing greater maternal investment. Infant primates often exhibit tantrums when their attempts to obtain maternal care are rejected.

Comparing hair-morphology and molecular methods to identify fecal samples from Neotropical felids.

PLoS ONE, 2017
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.
