Demographic buffering in natural populations: A multi‐level perspective

Journal of Animal Ecology, Volume 95, Issue 8, Page 1298-1310, August 2026.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Dental Calculus Formation Is Linked to Diet and Phylogeny in Mammals

Ecology and Evolution, Volume 16, Issue 7, July 2026.
In a survey of > 1600 specimens across all mammalian orders, we found that most species present dental calculus. We found calculus production to be strongly associated with herbivory, and we provide recommendations for the use of dental calculus in collections‐based research. ABSTRACT The oral microbiome is implicated in a wide diversity of fundamental

Revisiting the status of the Arctic's Last Ice Area as a refuge for marine predators

Ecosphere, Volume 17, Issue 7, July 2026.
Abstract The Last Ice Area (LIA), located north of the Canadian Arctic Archipelago and Greenland, has the Arctic's oldest and thickest sea ice. The LIA is hypothesized to be a potential climate refuge for ice‐dependent top predators as Arctic sea ice continues to decline.

Expanding the Ecological Application of Invertebrate‐Derived DNA (iDNA) for Monitoring Terrestrial Mammals Using a Single‐Species Approach

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
A novel single‐species, invertebrate‐derived eDNA (iDNA) method is presented for identifying European Brown Bear presence. Fly‐borne bear DNA remains readily identifiable for 24 h within flies and can be detected when just one fly in 20 has fed on bear scat. The method is effective both in laboratory and field settings. ABSTRACT Successful conservation

Consumption of anthropogenic foods influences the nutritional and reproductive condition of hunter‐harvested black bears

Wildlife Biology, Volume 2026, Issue 4, July 2026.
The consumption of human food subsidies influences ecological processes, and can affect individual behavior and fitness with population level changes in abundance and distribution. American black bears Ursus americanus often consume human food subsidies, which have been correlated with increased bear body size, age‐specific fertility and mortality ...

Enhanced biological processes associated with alopecia in polar bears (Ursus maritimus) [PDF]

Science of The Total Environment, 2015
Populations of wildlife species worldwide experience incidents of mass morbidity and mortality. Primary or secondary drivers of these events may escape classical detection methods for identifying microbial insults, toxin exposure, or additional stressors.

Avian influenza overview March–May 2026

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract Between 28 February and 4 June 2026, 949 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (186) and wild (763) birds in 30 countries in Europe. The downward trend in the number of detections observed at the end of the previous reporting period continued and is expected to persist throughout the summer ...

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

Biological Reviews, Volume 101, Issue 3, Page 1463-1478, June 2026.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,
