The roles of sex, mass and individual specialisation in partitioning foraging-depth niches of a pursuit-diving predator [PDF]
Intra-specific foraging niche partitioning can arise due to gender differences or individual specialisation in behaviour or prey selection. These may in turn be related to sexual size dimorphism or individual variation in body size through allometry ...

Avian influenza overview June–September 2025
Abstract Between 7 June and 5 September 2025, 183 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (27) and wild (156) birds across 15 countries in Europe. Although HPAI A(H5N1) virus detections were predominant in western and southwestern Europe, they also occurred on the northernmost coast of Norway. More than

ABSTRACT Agents of taphonomy can bias skeletal parts and the frequency of bones in archaeological sites. An important factor to consider is the possible effect of bone density‐mediated attrition on archaeornithological assemblages. We scanned willow ptarmigan (Lagopus lagopus) specimens using a Lunar iDXA and an enCcore small animal body add‐on to ...

Validating accelerometry estimates of energy expenditure across behaviours using heart rate data in a free-living seabird [PDF]
Two main techniques have dominated the field of ecological energetics, the heart-rate and doubly labelled water methods. Although well established, they are not without their weaknesses, namely expense, intrusiveness and lack of temporal resolution.

ABSTRACT Anthropogenic pollution can have detrimental effects on organismal physiology, behavior, and fitness, but the underlying genomic mechanisms mediating these effects are not well understood. Epigenetic regulation, such as DNA methylation, has been proposed as a potential mechanism mediating these effects, but currently, there are few studies in ...
