Oncilla Robot: A Versatile Open-Source Quadruped Research Robot With Compliant Pantograph Legs [PDF]

Frontiers in Robotics and AI, 2018
We present Oncilla robot, a novel mobile, quadruped legged locomotion machine. This large-cat sized, 5.1 kg robot is one of a kind of a recent, bioinspired legged robot class designed with the capability of model-free locomotion control.

First Locality Record of Melanistic Oncilla (Leopardus tigrinus) in Monteverde, Costa Rica [PDF]

Neotropical Biology and Conservation, 2021
The persistence of the coat color polymorphism melanism has been reported for several tropical felids, but its evolutionary advantages remain an active area of research.

Distribution and habitat use patterns of the endangered Central American clouded oncilla (Leopardus pardinoides oncilla) in Costa Rica. [PDF]

PLoS One
Montane cloud forests are highly threatened ecosystems that are vulnerable to climate change. These complex habitats harbor many species that suffer the negative consequences of this global phenomenon, such as shifts in their distribution and habitat use.

THE ONCILLA LEOPARDUS TIGRINUS ONCILLA (SCHREBER, 1775)

Tecnociencia
This study reports the occurrence of Leopardus tigrinus oncilla from eastern Panama. This is only the third such report of its presence across Panama, which expands the known distribution of this species to nearly the entire country.

Shadows in the forest: Uncovering unusual colouration records in mammals from the Ecuadorian Tropical Andes [PDF]

Biodiversity Data Journal
Variations in colouration patterns have been reported in numerous wildlife species, particularly birds. However, the increased use of camera traps for wildlife monitoring has enabled the detection of elusive species and phenotypic variations that might ...

Abundance changes and activity flexibility of the oncilla, Leopardus tigrinus (Carnivora: Felidae), appear to reflect avoidance of conflict [PDF]

Zoologia (Curitiba), 2012
We investigated the density and activity of the oncilla, Leopardus tigrinus (Schreber, 1775), a threatened small cat, in the Brazilian Atlantic Forest, using camera-trap data.

Ecological modeling, biogeography, and phenotypic analyses setting the tiger cats’ hyperdimensional niches reveal a new species [PDF]

Scientific Reports
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 ...

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

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.
