Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle

Journal of Zoology, Volume 329, Issue 1, Page 25-37, May 2026.
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

How much biotic nativeness matters across human demographic groups

Conservation Biology, Volume 40, Issue 2, April 2026.
Abstract Many central concepts of conservation biology—such as nativeness—are structured by ecological and social factors. However, the social consequences of using these concepts to make conservation decisions remain inadequately understood. Some researchers argue that nativeness, rather than acting as an objective proxy for important ecological ...

Variable social organization and breeding system of a social parrot revealed by genetic analysis

Ibis, Volume 168, Issue 2, Page 451-464, April 2026.
Social organization and contributions to reproduction vary widely within and between species that breed in groups. Such variation often arises from the process of group formation, which drives patterns of relatedness and hence the degree of social conflict and co‐operation between group members.

Fine‐Scale Genomic Divergence in the Amazonian Pirarucu (Arapaima gigas) Highlights the Need for Local Management Strategies

Freshwater Biology, Volume 71, Issue 3, March 2026.
ABSTRACT Freshwater habitats face significant human disturbances globally, impacting food security and ecosystems. Protected areas can mitigate biodiversity loss, but limited data on population connectivity hinders conservation management. This study examines pirarucu (Arapaima gigas), a heavily exploited and threatened Amazonian fish, using genomic ...

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.

Biological corridors are crucial habitat features that boost biodiversity in agroecological systems of Argentina

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
Our work shows for the first time in the region that biological corridors increase biodiversity and promote interactions between different components of the production system, using a methodology never before used in Argentina such as the Griffon index.
