Exploring dietary adaptations in Ursus minimus: a 3D geometric morphometric analysis of the mandible

Boreas, Volume 55, Issue 2, Page 443-453, April 2026.
Using 3D geometric morphometrics, the dietary adaptations of the extinct Auvergne bear (Ursus minimus) are analysed. Its mandibular morphology aligns more closely with omnivorous rather than insectivorous bears, challenging current ideas. The extinct bear Ursus minimus, which lived in Europe during the Pliocene and possibly Early Pleistocene, is ...

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.

First description of the baubellum in the spectacled bear Tremarctos ornatus (Mammalia: Ursidae)

Journal of Anatomy
AbstractThe baubellum (os clitoridis) is a bone found in the clitoris of many female eutherian mammals and is homologous to the baculum in males. In contrast to the baculum, the baubellum has received very little attention regarding its morphological or interspecific diversity, or on hypotheses for its function.

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
