Epidemiological Dynamics of a Visually Apparent Disease: Camera Trapping and Machine-Learning Applied to Rumpwear in the Common Brushtail Possum. [PDF]

Integr Zool
Visually apparent diseases are valuable for investigating and monitoring the occurrence and prevalence of pathogens in wildlife populations through passive monitoring methods like camera trapping. Rumpwear is characterized by visible signs of hair breakage and damage on the lumbosacral region of common brushtail possums.

Andean bears (Tremarctos ornatus) display selective behaviors while foraging bromeliads (Puya spp.) in high elevation puna grasslands. [PDF]

PLoS ONE
Andean bears (Tremarctos ornatus) forage extensively on bromeliads (Puya spp.) across their range, although their selectivity for bromeliads is less understood. We report on foraging activity by Andean bears on two species of bromeliad, Puya leptostachya

Small vertebrates in the spectacled bear’s diet (Tremarctos ornatus Cuvier, 1825) in the north of Peru [PDF]

Revista Peruana de Biología, 2016
There have been numerous studies about Spectacled bear´s diet, however little is known about the small vertebrates it consumes. This study present nine vertebrate species (seven rodent and two birds) as preys of the Spectacled bear, based on the analysis

Microsatellite Analysis of the Spectacled Bear (Tremarctos ornatus) Across its Range Distribution

Genes & Genetic Systems, 2005
DNA samples of the spectacled bear (Tremarctos ornatus) from five Andean countries, Venezuela, Colombia, Ecuador, Peru and Bolivia, were analyzed for nine microsatellite loci. Seven of them were polymorphic, which led us to investigate several population-genetic parameters.

A Genetic Tool to Identify Predators Responsible for Livestock Attacks in South America and Recommendations for Human–Wildlife Conflict Mitigation [PDF]

Animals
Livestock predation induces global human–wildlife conflict, triggering the retaliatory killing of large carnivores. Although domestic dogs (Canis familiaris) contribute to livestock depredation, blame primarily falls on wild predators.

Data gaps and heterogeneity limit our understanding of human–wildlife interactions: A continental study of Andean bears

People and Nature
The expansion and intensification of human activities have increased interactions between people and wildlife. Interactions involving bears and other large carnivores are complex and can lead to conflicts. Promoting positive coexistence requires managing

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots. [PDF]

Conserv Biol
Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

Epigenetic Clock in Bears: A Simple Cost-Effective Blood DNA Methylation-Based Age Estimation Method Applicable to Multiple Bear Species. [PDF]

Ecol Evol
Age is an essential factor to understand the life history and demographic parameters of wildlife. In this study, we built a common epigenetic clock model for multiple bear species, including brown, Asian black, polar, sun, and Andean bears. The model will contribute to ecological research, conservation, and management of bear species.

Roads, forest cover, and topography as factors affecting the occurrence of large carnivores: The case of the Andean bear (Tremarctos ornatus)

Global Ecology and Conservation, 2021
Global declines in large-bodied terrestrial vertebrates are widely linked to human disturbance and habitat loss. Identifying remaining opportunities to conserve areas wherein such species may persist or might be reintroduced has thus become a key ...
