Intraspecific variability in feather moult extent declines under both low and high constraints

Functional Ecology, Volume 40, Issue 8, Page 2350-2362, August 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Intraspecific trait variability (ITV) is a fundamental feature of biological populations and the raw material upon which natural selection acts, yet its drivers remain poorly understood.

Maternal glucocorticoids have persistent effects on offspring social phenotype irrespective of opportunity for social buffering

Journal of Animal Ecology, Volume 95, Issue 8, Page 1326-1338, August 2026.
This study tests whether early‐life maternal association buffers offspring from the effects of prenatal stress in a facultatively social lizard. Despite clear effects of maternal glucocorticoids on growth and social behaviour, social associations did not mitigate these effects, revealing limits to social buffering in this species.

Social information about others' affective states in a human‐altered world

Journal of Animal Ecology, Volume 95, Issue 8, Page 1311-1325, August 2026.
Faced with anthropogenic change, animals now encounter challenges different from their evolutionary past. To cope with such challenges, animals may use social information about others' affective states to guide their decisions. Considering affective states of wild animals could have important implications for animal welfare and wildlife conservation ...

Environmental factors associated with nesting habits and age shape the composition and connection between skin and uropygial gland microbiomes of birds

Journal of Animal Ecology, Volume 95, Issue 8, Page 1435-1452, August 2026.
This study provides new insights into how ecological conditions influence the evolution of host‐associated symbiotic communities and their functional roles. The findings suggest that pathogen pressures linked to nesting habits in birds shape bacterial communities of the uropygial gland, and their connection with the skin microbiome, where the ...

The role of viability selection in shaping short‐ and long‐term consequences of early‐life conditions: An experiment in the Alpine swift

Journal of Animal Ecology, Volume 95, Issue 8, Page 1401-1418, August 2026.
In an experimental brood‐size manipulation in Alpine swifts, smaller nestlings were selectively lost during growth, eliminating treatment differences in adult size, yet individuals from enlarged broods showed higher reproductive performance. Abstract Environmental conditions experienced early in life can shape growth, morphology and survival, and can ...
