The genetic structure of the spectacled bear (Tremarctos ornatus; Ursidae, Carnivora) in Colombia by means of mitochondrial and microsatellite markers

Journal of Mammalogy, 2020
The spectacled bear (Ursidae: Tremarctos ornatus) is an emblematic umbrella species and one of the top carnivores in the Andean mountains. It is also listed as vulnerable by IUCN and as endangered by CITES.

Comparative Trends of Sociality Among Terrestrial Carnivores: A Multivariate Analysis 陆生食肉动物社会性的比较趋势:一项多变量分析

Wildlife Letters, Volume 4, Issue 1, Page 10-22, March 2026.
In this study we analyze the role of phylogeny, environment, and community structure on sociality. Using structural equation modeling (SEM) we aim to quantify the direct and indirect impacts of variables on behaviors including social grouping, reproduction, and space use among Carnivora species.

大熊猫分类地位的探讨

野生动物学报, 1987
研究大熊猫的免疫分类学性状,并讨论大熊猫在解剖学、遗传学和分子生物学方面的特征,认为大熊猫与熊类亲缘关系密切是无可辩驳的。主张大熊猫更为适宜的分类地位是并入熊科（Ursidae）,再立大熊猫亚科（A11uropodinae）。问题的提出关于大熊猫和小熊猫在分类学上的地位,一百多年来一直是生物学上一个难解之谜。虽然有不少学者,尤其是我国的学者把大熊猫划为独立的一科,把小熊猫划入浣熊科 （Procyonidae）,但是纵观发表的50篇论文表明,把大熊猫分为熊科（Ursidae）、浣熊科和自成大熊猫科 ...

Scat DNA Applications for Low‐Density Carnivore Survey: Techniques, Efficiency and Future Directions

Mammal Review, Volume 56, Issue 1, March 2026.
We reviewed 338 studies encompassing mostly Felidae, Canidae and Mustelidae species throughout the world, confirming scat DNA as a reliable genetic source for many applications. The findings here offer guidance for future studies on low‐density carnivores, helping to design cost‐effective research and improving data quality for conservation efforts ...

The Brain Anatomy of the Brown Bear (Carnivora, Ursus arctos L., 1758) Compared to That of Other Carnivorans: A Cross-Sectional Study Using MRI

Frontiers in Neuroanatomy, 2019
In this study, we aimed to provide a neuroanatomy atlas derived from cross-sectional and magnetic resonance imaging (MRI) of the encephalon of the brown bear (Ursus arctos). A postmortem brain analysis using magnetic resonance imaging (MRI – 1,5T; a high-
