Population Genomic Structure and Demographic History of Black Guillemots Breeding Across the North Atlantic

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Identifying distinct genetic populations is important for successful species conservation and management. We used double‐digest restriction‐site associated DNA sequencing (ddRADseq) to look at how 172 black guillemots from different regions in the Arctic and North Atlantic oceans differed genetically.

American kestrel population trends and vital rates at the continental scale

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract The American kestrel (Falco sparverius, hereafter referred to as kestrel) has declined across much of its North American range since at least the mid‐1960s. Kestrel population dynamics have been explored through a multitude of local studies and two broad reviews of available data. Across large geographic extents, however, the demographic cause(

Bulk tissue versus amino acid carbon stable isotopes to reveal the diet and basal resource use of an invasive rodent

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract Stable isotope analysis (SIA) is widely used to reconstruct food webs, characterize trophic relationships, and estimate dietary composition. However, bulk tissue SIA (BSIA) can yield imprecise estimates when dietary sources are isotopically similar.

Flooding and a complex predator community drive American oystercatcher nest and chick survival in Virginia

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We investigated low American oystercatcher (Haematopus palliatus) productivity in the Virginia barrier islands, which historically supported high oystercatcher reproductive success. We found that chick survival was lower than nest survival, and that management may need to adapt to address evolving threats from coastal flooding and a multi‐guild ...

Sex matters: European urban birds flee approaching women sooner than approaching men

People and Nature, Volume 8, Issue 2, Page 316-326, February 2026.
Abstract Flight initiation distance (FID) is a metric often used to study an individual's perceptions of risk when facing a predatory threat. Longer FID indicates lower risk‐taking, while shorter FID identifies bolder individuals who tolerate greater risk.

Migratory connectivity and barrier‐crossing flights of Vermivora warblers are associated with synoptic weather conditions

Journal of Animal Ecology, Volume 95, Issue 2, Page 327-344, February 2026.
Tracking data from ~10 g songbirds illuminate how weather conditions affect the initiation of long‐distance migratory flights across the Gulf of Mexico during autumn and spring. Seasonal differences and weak migratory connectivity near the Gulf suggest adaptive responses to weather, with future climate trends potentially reducing crossing favorability ...

Assemblage, archive, and ancestor: Developing more‐than‐human historical geography with salmon

Geographical Research, Volume 64, Issue 1, February 2026.
This paper interrogates recent geographic literature on the more‐than‐human archive and argues that there needs to be more specificity when conceptualising and researching the more‐than‐human. It then answers this call for specificity by theorising three modes of more‐than‐human historical geography that are developed through empirical encounters with ...
