Understanding transmission routes of parasites and pathogens is critical for the development of control measures and mitigation of impacts on host populations. Trichomonas gallinae is a widespread pa...

A crew from Whitby lands two of the migratory species weighing over 300kg each in as many days.

Analyses of the relationship between taxon richness and multi-trophic ecosystem functioning across marine, lake, stream and soil ecosystems show that food web complexity underlies biodiversity effects...

Abstract. Variation in daylight hours may shape light-dependent behaviours both across seasons and among latitudinally distinct breeding colonies. We inves

AviList is a collaborative global effort to produce a single current consensus taxonomy for the birds of the world, along with key information on taxonomy and nomenclature. The checklist is free for d...

Reflections from our Executive Editor, Dr Nate Sanders Image of Charles Elton. Credit: Wikimedia Commons Nearly 100 years ago, a 27-year-old Charles Elton published Animal Ecology, a foundational b…

Modelling the unprecedented avian panzootic caused by High-Pathogenicity Avian Influenza (HPAI) across the Northeast Atlantic gannet breeding metapopulation, we estimated 28% (95% CI: 21%–34%) HPAI-r...

At this critical moment when misinformation about sex is being applied to policy globally, scientific clarification on the definition of biological sex is valuable. Here, we evaluate the primary appr...

Abstract. Habitat loss contributes to extinction risk in multiple ways. Genetically, small populations can face an ‘extinction vortex’—a positive feedback

For anyone who still wants to pretend that the grouse shooting industry isn’t responsible for the systematic extermination of Hen Harriers on grouse moors across the UK, here’s the latest catalogue…

Life-history theory predicts a trade-off between allocation of resources to reproduction or self-maintenance, yet how environmental variability shapes this trade-off remains poorly understood. We sho...

A warming climate has helped some to flourish, researchers say, but the outlook is troubling.

Across their entire Atlantic breeding range, Atlantic puffins Fratercula arctica have experienced decreases in food availability, often leading to population declines. The species is one of the most ....

Widespread declines in common species raise concerns, but links to extinction risk and climate change remain unclear. Here, the authors show that many small climate change effects can accumulate to dr...
