First Record of Mating Involving a Melanistic Jaguar (Panthera onca) in the Wild: Novel Behavioural Insights Into Colour Morphs and Captive‐Wild Comparisons [PDF]

Ecology and Evolution
Many threatened felid species, including the jaguar (Panthera onca), have low reproductive success in captivity. This may be partially attributed to a lack of knowledge on natural history parameters like courtship and mating behaviour in wild animal ...

Feature Selection for Supervised Learning and Compression

Applied Artificial Intelligence, 2022
Supervised feature selection aims to find the signals that best predict a target variable. Typical approaches use measures of correlation or similarity, as seen in filter methods, or predictive power in learned models, as seen in wrapper methods. In both

Beyond words: From jaguar population trends to conservation and public policy in Mexico.

PLoS ONE, 2021
The jaguar (Panthera onca) is one of the most threatened carnivores in the Americas. Despite a long history of research on this charismatic species, to date there have been few systematic efforts to assess its population size and status in most countries

Assessing the umbrella value of a range-wide conservation network for Jaguars (Panthera onca) [PDF]

, 2016
Umbrella species are employed as conservation short-cuts for the design of reserves or reserve networks. However, empirical data on the effectiveness of umbrellas is equivocal, which has prevented more widespread application of this conservation strategy.
