Living high and at risk: predicting Andean bear occurrence and conflicts with humans in southeastern Peru

Global Ecology and Conservation, 2022
Human encroachment into wildlife habitat threatens the persistence of large carnivore populations because it shrinks their distribution and promotes conflicts related to agricultural and livestock damage.

Fossil bears break free from inhibitory cascade constraints at least twice (Ursus minimus and Ursus deningeri) caused by dietary adaptations

Boreas, Volume 55, Issue 2, Page 503-516, April 2026.
Bears deviate from the inhibitory cascade model (ICM) during molar size evolution, with two significant deviations linked to changes in diet: Ursus minimus and Ursus deningeri. Many bears exhibit a ‘partial ICM’, highlighting the relationship between relative molar size, dietary adaptations and dental development across different species.

FOGS: A SNPSTR Marker Database to Combat Wildlife Trafficking and a Cell Culture Bank for Ex‐Situ Conservation

Molecular Ecology Resources, Volume 25, Issue 4, May 2025.
ABSTRACT Illegal wildlife trade is a growing problem internationally. Poaching of animals not only leads to the extinction of populations and species but also has serious consequences for ecosystems and economies. This study introduces a molecular marker system that authorities can use to detect and substantiate wildlife trafficking.

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

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

The influence of domestic dogs on the spatial and temporal distribution of tayra

Wildlife Biology, Volume 2025, Issue 2, March 2025.
The domestic dog Canis familiaris is an exotic species known to have impacts on native fauna and it may induce spatial and temporal segregation in other species as a mechanism to reduce agonistic interactions. The tayra Eira barbara, a medium‐sized, widely distributed mustelid, is one of the species that can be affected.

Indicios indirectos de la presencia del oso andino (Tremarctos ornatus Cuvier, 1825) en el noroeste de Argentina Indirect evidence on the presence of the Andean bear (Tremarctos ornatus Cuvier, 1825) in northwestern Argentina

Revista del Museo Argentino de Ciencias Naturales, 2009
La presencia de osos andinos (Tremarctos ornatus) en Argentina ha sido muy discutida debido a la ausencia de evidencia confirmativa. Muchos expertos en el oso dudan actualmente de su presencia en el país.

A global assessment of large terrestrial carnivore kill rates

Biological Reviews, Volume 100, Issue 1, Page 327-350, February 2025.
ABSTRACT Through killing and instilling fear in their prey, large terrestrial carnivores shape the structure and function of ecosystems globally. Most large carnivore species have experienced severe range and population declines due to human activities, and many are now threatened with extinction.

Molecular population genetic analysis of the spectacled bear (Tremarctos ornatus) in the northern Andean area [PDF]

Hereditas, 2003
Eighty-two Andean bear samples obtained in three South American Andean countries were analyzed using five hypervariable microsatellite markers. Neither the overall sample nor the samples coming from each of the countries analyzed were in Hardy-Weinberg equilibrium.
