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

Journal 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 ...

Challenging the contest vs. scramble dichotomy in social competition: mixed conditions allow disparately ranked monkeys to get equivalent food but experiencing more competition still leads to risk-averse decisions. [PDF]

Dietary resilience of coral reef fishes to habitat degradation

Journal of Animal Ecology, EarlyView.
Metabarcoding of gut contents shows that two common benthic‐feeding reef fishes with different feeding stratgies—a butterflyfish (Chaetodon capistratus) and a hamlet (Hypoplectrus puella)—shift diets on degraded reefs. These shifts mirror contrasting patterns in body condition: butterflyfish showed strong individual variation, whereas condition was ...

Early life exploration behaviour and life‐history loci are colocalized in an adaptive genomic hotspot in Atlantic salmon

Journal of Animal Ecology, EarlyView.
The genetic architecture of phenotypic correlations offers insights into how natural selection operates in the wild. Two functional phenotypes in Atlantic salmon, early life exploration and age‐at‐maturity, are correlated at an adaptive genomic hotspot, but through distinct genetic markers (SNPs), ruling out causality.

Record phenological responses to climate change in three sympatric penguin species

Journal of Animal Ecology, EarlyView.
This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

Habitat imprinting in breeding territory selection of a long‐lived bird of prey

Journal of Animal Ecology, EarlyView.
A unique long‐term dataset has allowed this study of an important habitat selection mechanism, habitat imprinting, in a species which is typically extremely challenging to study. It gives us better understanding of the role of early experience in selection of breeding sites in long‐lived species with high breeding site fidelity.
