Jaguar Densities and Land Cover Change in a Multi‐Use Landscape: A 10‐Year Comparison in the Colombian Llanos 美洲豹种群密度与复合用地景观下的土地覆被变化:哥伦比亚亚诺斯地区10年比较研究

open access: yesWildlife Letters, EarlyView.
We used spatially explicit capture‐recapture to estimate jaguar densities in a private reserve in the Colombian Llanos and quantified land cover change in and around the reserve from 2014 to 2024. Densities increased 22% since 2014, while disturbed land cover increased by 39%–54% around the reserve depending on buffer distance. Our study indicates that

Roaring to Go: Engagement With Positive Reinforcement Training as a Valid and Reliable Indicator of Positive Welfare in Zoo Big Cats

open access: yesZoo Biology, EarlyView.
A figure summarising the information conveyed by the abstract in graphical form ABSTRACT Engagement with positive reinforcement training is a non‐invasive, easily recorded, and valid indicator of welfare in captive bottlenose dolphins. However, despite the ubiquitousness of training programs in zoo‐housed mammals in accredited zoos, this metric has yet

Anthropogenic and environmental correlates of spatial patterns of co-occurrence of small felids in a montane landscape

open access: yesGlobal Ecology and Conservation
Understanding how sympatric small felids respond to their environmental surroundings in a human matrix landscape is important to determine their habitat use, distribution and conservation.

Adjusting Our Thinking About Feeding Animals: Fiber as the Metric for Mimicking Natural Diets

open access: yesZoo Biology, EarlyView.
A typical effect of the change of an animal group to a diet higher in fiber: juveniles keep growing, animals of ideal body weight maintain their weight, and obese individuals lose weight. ABSTRACT Free‐ranging animals often ingest markedly different diets than their counterparts under human care, whether companion animals, production animals, or zoo ...

Non-invasive assessment of stress hormones, parasites, and diet, using scat of five felid species in Belize, Central America

open access: yes, 2014
Many Neotropical felid species, such as jaguars, are threatened with extinction due to habitat fragmentation and/or human persecution. Human activities around protected areas in Belize, Central America, are increasing and so are levels of human-felid ...

Testicular Echobiometry and Sperm Characterization in Oncilla (Leopardus tigrinus) From the Caatinga Biome

open access: yesZoo Biology, EarlyView.
We describe testicular echobiometry and sperm characterization in oncilla (Leopardus tigrinus) from the Caatinga biome, Ceará, Brazil. ABSTRACT Among neotropical small felids, the Leopardus tigrinus is classified as vulnerable by the International Union for Conservation of Nature, but studies on reproductive morphology and physiology are scarce for ...

A sabre-tooth felid from Coopers Cave (Gauteng, South Africa) and its implications for Megantereon (Felidae: Machairodontinae) taxonomy [PDF]

open access: yes, 2007
Metrical and morphological analysis of a new sabre-tooth felid mandible recovered from the Plio-Pleistocene hominid-bearing site of Coopers, South Africa, indicates that it can be assigned to the genus Megantereon, though it is by some measures the ...

Effects of Roscovitine and Serum Starvation on the Viability and G0/G1 Synchronization in Somatic Cells from the Antillean Manatee (Trichechus manatus manatus, Linnaeus 1758)

open access: yesZoo Biology, EarlyView.
ABSTRACT The success of nuclear reprogramming techniques, including the G0/G1 synchronization of somatic cells, depends on species‐specific optimization. While roscovitine and serum starvation have been successfully applied in domestic and wild terrestrial mammals, their use in aquatic mammals remains poorly investigated.
