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, EarlyView.
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.

Comparative Analysis of Olfactory Receptor Repertoires Sheds Light on the Diet Adaptation of the Bamboo-Eating Giant Panda Based on the Chromosome-Level Genome

Animals, 2023
The giant panda (Ailuropoda melanoleuca) is the epitome of a flagship species for wildlife conservation and also an ideal model of adaptive evolution. As an obligate bamboo feeder, the giant panda relies on the olfaction for food recognition.

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

Integrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.

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

Boreas, EarlyView.
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 ...

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

Boreas, EarlyView.
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.

New perspectives on head and neck allometry and ecomorphology in tetrapods

Biological Reviews, EarlyView.
ABSTRACT The skull and neck are vital parts of the body, influencing feeding ecology, habitat exploitation and locomotion. Numerous studies have therefore sought to understand how the size of these segments vary with ecology and scale with overall body size.

Bears into the Niche-Space: Phylogeography and Phyloclimatic Model of the Family Ursidae

Diversity
Assessing niche evolution remains an open question and an actively developing area of study. The family Ursidae consists of eight extant species for which, despite being the most studied family of carnivores, little is known about the influence of ...

Late Pleistocene carnivores (Carnivora: Mammalia) from a cave sedimentary deposit in northern Brazil

Anais da Academia Brasileira de Ciências, 2014
The Brazilian Quaternary terrestrial Carnivora are represented by the following families: Canidae, Felidae, Ursidae, Procyonidae Mephitidae and Mustelidae. Their recent evolutionary history in South America is associated with the uplift of the Panamanian

Detection of Ursid Gammaherpesvirus 2 in Asiatic Black Bears (Ursus thibetanus) With Keratoconjunctivitis

Veterinary Ophthalmology, EarlyView.
ABSTRACT Objective To investigate the potential contribution of herpesvirus infection in the development of ocular surface disease in Asiatic black bears (Ursus thibetanus). Animals Studied Eight captive Asiatic black bears housed at a wildlife sanctuary were examined during routine health assessments.

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 ...
