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

open access: yesJournal of Animal Ecology, EarlyView.
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.

Seasonal body mass dynamics mediate life‐history trade‐offs in a hibernating mammal

open access: yesJournal of Animal Ecology, EarlyView.
We tested a suite of ecological hypotheses to explain variation in seasonal body mass dynamics of a fat‐storing mammalian hibernator. We further demonstrated that pre‐hibernation mass gain in ground squirrels mediates an annual allocation trade‐off between current and future reproduction as the squirrels forage and rear young under predation risk ...

Cohorts of immature Pteropus bats show interannual variation in Hendra virus serology

open access: yesJournal of Animal Ecology, EarlyView.
Pteropus bat with offspring, photo taken by Manuel Ruiz‐Aravena. Abstract Understanding the drivers of seasonal disease outbreaks remains a fundamental challenge in disease ecology. Periodic outbreaks can be driven by several seasonally varying factors, including pulses of susceptible individuals through births, changes in host behaviour and social ...

Early‐life stasis in partial seasonal migration is underpinned by among‐cohort variation in migratory plasticity and selective disappearance

open access: yesJournal of Animal Ecology, EarlyView.
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
