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

Interaction Between Traditional Fishers and the Neotropical Otter Lontra longicaudis (Olfers, 1818) in a Brazilian Amazon Estuary

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.
ABSTRACT The neotropical otter Lontra longicaudis (Olfers, 1818) is a semi‐aquatic carnivore from the Mustelidae family with a piscivorous habit that interacts with riverine populations because of fishing resources, and this relationship is often negative, especially in the Amazon where fishing represents an important activity for several communities ...

Caught on Camera: Insights Into Mizoram's Mammalian Diversity Through a Camera‐Trap‐Based Distance Sampling Approach

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Mizoram's study revealed low ungulate densities and abundance, suggesting illegal hunting as a cause and entailing conservation urgency. ABSTRACT Assessing species distribution and associated threats is crucial for effective conservation. Many species including mammals face extinction due to habitat loss, hunting, and illegal trade, with their ...

Extinct Pleistocene carnivores were diurnal and highly active

Ecography, Volume 2025, Issue 12, December 2025.
There is much contention over the causes and correlates of megafaunal extinctions at the end of the Pleistocene. A major role for human impact such as hunting has been discussed widely. If correct, the overkill hypothesis explains not only why large mammals in general were highly prone to extinction but suggests that extinction may have been selective ...

An evaluation of techniques used for the capture, immobilization and radio collaring of Saharan striped polecat

Wildlife Society Bulletin, Volume 49, Issue 4, December 2025.
Summary of methods for capturing, immobilizing, and radio collaring Saharan striped polecats in central Tunisia (2019–2022). Spotlighting with a hand net was the only effective capture technique, and ketamine–medetomidine provided adequate handling time. ATS and WMI collars, with flexible antennas and cable‐tie attachments, performed best.

Pliocene Forest Fragmentation Shaped Speciation in Tropical Asia's Giant Squirrels (Ratufa)

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Tropical Asia's complex, dynamic geological and climatic history, coupled with its diverse topography, provides a fascinating setting to study evolutionary processes driving high biodiversity. This phylogenomic research reconstructs the evolutionary history of the strictly arboreal and forest‐dependent Oriental Giant Squirrels (Ratufa) to gain

Avian influenza overview September–November 2025

EFSA Journal, Volume 23, Issue 12, December 2025.
Abstract Between 6 September and 28 November 2025, 2896 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (442) and wild (2454) birds in 29 countries in Europe. The magnitude and geographical extent of these detections were unprecedented for this time of the year, particularly in wild birds.
