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 ...

Avian influenza overview December 2025–February 2026

EFSA Journal, Volume 24, Issue 3, March 2026.
Abstract Between 29 November 2025 and 27 February 2026, 2514 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (406) and wild (2108) birds in 32 countries in Europe. Albeit still at high levels after the peak was reached at the beginning of the current reporting period, the weekly number of detections has since ...

Craniometric Characteristics of Selected Carnivora Species Kept in Captivity in Relation to Bite Force and Bending Strength of the Upper Canines

Animals
The aim of this study was to analyse the bite forces of seven species from three carnivore families: Canidae, Felidae, and Ursidae. The material consisted of complete, dry crania and mandibles.

Serosurveillance of Leishmania infantum in Zoo‐Kept Animals in Spain

Zoonoses and Public Health, Volume 73, Issue 1, Page 65-73, February 2026.
ABSTRACT Introduction Leishmaniosis is a sand fly‐borne zoonosis mainly caused by Leishmania infantum in Europe. Exposure to this protozoan has been widely reported in many domestic and wild species. However, epidemiological surveys evaluating the circulation of L. infantum in zoo‐kept animals remain limited. This large‐scale study aims to evaluate the

Integrating ZooMS and Zooarchaeology to Assess the Châtelperronian and Carnivore Occupations at Cassenade (Dordogne, France)

PaleoAnthropology
Archaeological animal bone assemblages are often highly fragmented, meaning that for over 70% of the recovered bone fragments we do not know what animal (or human) species they belonged to.

An Energetic Tradeoff Best Explains Parturition Timing in Grizzly Bears

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Capitalizing on latitudinal denning‐chronology variation among four grizzly bear populations in interior North America, and using grizzly bear parturition dates (27 Dec–28 Feb) previously predicted from anomalous daily motion counts, we found evidence supporting the hypothesis that birth is optimally timed relative to den exit to balance an energetic ...

Predators and scavengers: Polar bears as marine carrion providers

Oikos, Volume 2026, Issue 1, January 2026.
Scavenging is a foraging strategy widely used across the animal kingdom and apex predators provide a large amount of energy in a food web by provisioning carrion. In the harsh environmental conditions of the Arctic, apex predators such as polar bears Ursus maritimus can provide scavenging opportunities for many species. Carrion can act as a buffer when

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 ...
