Our study demonstrates how life history trade‐offs and pair bonds influence winter roosting in red kites. Analysing long‐term GPS data from 216 individuals, we reveal marked behavioural plasticity in communal roosting: young, non‐breeding males are most likely to join communal roosts, whereas breeding pairs predominantly roost together near their ...

The evolution of female social relationships in nonhuman primates [PDF]
Considerable interspecifc variation in female social relationships occurs in gregarious primates, par- ticularly with regard to agonism and cooperation be- tween females and to the quality of female relationships with males.

Changes to mean early‐life phenotypes are fundamentally driven by joint dynamics of plasticity and selection, but such effects are rarely quantified. We show that cross‐cohort stasis in the degree of partial migration is underpinned by substantial within‐ and among‐cohort variation in plasticity and selection on migration, indicating high environmental

Glacial cycles promote greater dispersal, which can help explain larger clutch sizes, in north temperate birds [PDF]
Earth’s glacial history and patterns in the life history traits of the planet’s avifauna suggest the following interpretations of how recent geological history has affected these key characteristics of the biota: 1) Increased colonizing ...

Perspectives on the Effect of Incubation Temperature on Pine Snake Hatchlings
Effect of timing of egg‐laying and incubation temperature on the possible phenology of events for early egg‐laying females (laying June 15, the earliest laying date), the mid‐laying date (July 4), and late egg‐laying females (July 17, the latest egg‐laying date). Based on data from many papers.

ABSTRACT Measures of an organism's weight at a given length are often considered reliable indicators of energy reserves or ‘condition’, which can be related to fecundity and risk of mortality. Understanding the impact of environmental change on fish condition may therefore inform sustainable management of human activities in marine ecosystems.

Reproductive consequences of natal dispersal in a highly philopatric seabird [PDF]
Natal and breeding dispersal have a major impact on gene flow and population structure. We examined the consequences of natal dispersal on the reproductive success (proportion of pairs rearing chicks) of colonial-breeding Thick-billed murres (Uria lomvia)

ABSTRACT Rays are common marine mesopredators that use coastal and estuarine habitats during multiple life history stages for critical functions. They are long‐lived, late to mature, and have low reproductive output, making them vulnerable to and slow to recover from population threats such as overfishing and habitat loss.
