Pathologies of Oligacanthorhynchus pardalis (Acanthocephala, Oligacanthorhynchidae) in Leopardus tigrinus (Carnivora, Felidae) in Southern Brazil Patologias de Oligacanthorhynchus pardalis (Acanthocephala, Oligacanthorhynchidae) em Leopardus tigrinus (Carnivora, Felidae) no sul do Brasil

open access: yesRevista Brasileira de Parasitologia Veterinária, 2012
In Brazil, Oligacanthorhynchus pardalis (Westrumb, 1821) Schmidt, 1972 has been observed in five species of wild felines. In the present study, five roadkilled oncillas (Leopardus tigrinus Schreber, 1775) were collected in the State of Rio Grande do Sul,

A differentiable physics engine for deep learning in robotics [PDF]

open access: yes, 2019
An important field in robotics is the optimization of controllers. Currently, robots are often treated as a black box in this optimization process, which is the reason why derivative-free optimization methods such as evolutionary algorithms or ...

Camouflage or Coincidence? Investigating the Effects of Spatial and Temporal Environmental Features on Feral Cat Morphology in Tasmania

open access: yesEcology and Evolution, Volume 14, Issue 11, November 2024.
Feral cats (Felis catus) have spread across Australia over the past 200 years, displaying various coat types, yet it remains unknown if any offers an adaptive advantage. Using a dataset of 24,657 camera‐trap images, we examined if any coat types correlate with spatial or temporal features.

Transmission pathways and spillover of an erythrocytic bacterial pathogen from domestic cats to wild felids

open access: yesEcology and Evolution, Volume 8, Issue 19, Page 9779-9792, October 2018., 2018
Focusing on co‐occurring domestic and wild felids, we evaluate evidence of spillover and mechanisms of transmission for an erythrocytic bacterial parasite of cats. We undertake analyses of disease prevalence, transmission modeling, pathogen genotyping based on sequences of the bacterial 16S rRNA gene, and phylogenetic analysis with ancestral state ...

Estimating species distribution from camera trap by‐catch data, using jaguarundi (Herpailurus yagouaroundi) as an example

open access: yesDiversity and Distributions, Volume 30, Issue 10, October 2024.
Abstract Aim Planning conservation action requires accurate estimates of abundance and distribution of the target species. For many mammals, particularly those inhabiting tropical forests, there are insufficient data to assess their conservation status.

Trends in Medicinal Uses of Edible Wild Vertebrates in Brazil

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2017, Issue 1, 2017., 2017
The use of food medicines is a widespread practice worldwide. In Brazil, such use is often associated with wild animals, mostly focusing on vertebrate species. Here we assessed taxonomic and ecological trends in traditional uses of wild edible vertebrates in the country, through an extensive ethnobiological database analysis. Our results showed that at

The effect of colour vision status on the detection and selection of fruits by tamarins (Saguinus spp.) [PDF]

open access: yes, 2003
The evolution of trichromatic colour vision by the majority of anthropoid primates has been linked to the efficient detection and selection of food, particularly ripe fruits among leaves in dappled light.

Characterization of antimicrobial resistance profiles in Escherichia coli isolated from captive mammals in Ecuador

open access: yesVeterinary Medicine and Science, Volume 10, Issue 4, July 2024.
Among 90 E. coli isolates from 70 mammals, significant resistance was found to ampicillin (52.22%), ceftriaxone (42.22%) and cefuroxime (42.22%), with 27.78% being ESBL‐producing. Notably, 66.67% of isolates showed resistance to at least one antibiotic, and 35.56% exhibited multiresistant phenotypes.

Natural selection of melanism in jaguar and oncilla in Costa Rica

open access: yes, 2021
Introducción: La persistencia de los polimorfismos del color del pelaje, como la coexistencia del color del pelaje melánico (negro) y el "tipo salvaje" (manchado), es un enigma evolutivo. Objetivo: Probamos las predicciones de la Regla de Gloger y la hipótesis de la Segregación Temporal que proponen que los individuos melánicos (a) ocurrirán con mayor ...

Practical approaches to exploiting body dynamics in robot motor control [PDF]

open access: yes, 2015
Motor control systems in the brain of humans and mammals are hierarchically organised, with each level controlling increasingly complex motor actions. Each level is controlled by the higher levels and also receives sensory and/or proprioceptive feedback.
