Flight of the dragons: a global review of migration in Odonata

Biological Reviews, Volume 101, Issue 5, Page 2134-2157, October 2026.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

Counting cases, conserving species: addressing highly pathogenic avian influenza in wildlife

Biological Reviews, Volume 101, Issue 5, Page 2190-2213, October 2026.
ABSTRACT Highly pathogenic avian influenza (HPAI) has become a critical threat to wildlife, shifting from a seasonal epizootic to a persistent, year‐round panzootic with global consequences. Here, we summarise the origin, evolutionary mechanisms, and expanding host range of the current H5N1 virus (clade 2.3.4.4b) and assess its impact on wildlife. Over

Measuring Bird Morphology From Field Photographs

Ecology and Evolution, Volume 16, Issue 10, October 2026.
We evaluated a digital photography approach based on the pinhole camera model to estimate bird morphometric traits from single images, testing its accuracy under controlled conditions and across 37 species photographed in the field. Photographic measurements showed strong agreement with museum and database‐derived traits (ρ = 0.82–0.95), with wing and ...

Unpacking the drivers of gut‐passage times of seeds dispersed by frugivorous lemurs

Ecology, Volume 107, Issue 10, October 2026.
Abstract The impacts of endozoochory on plant populations are primarily determined by how seeds are processed in animal guts. Therefore, understanding the factors that determine how long seeds remain in the gut is crucial for predicting the outcomes of animal‐mediated seed dispersal.
