Predation Risk Does Not Delay Breeding but Reduces Nest Survival in High‐Arctic Shorebirds
Ecology and Evolution, Volume 16, Issue 3, March 2026.We assessed the impact of arctic foxes' predation pressure on two sympatric sandpiper species. Fox activity influenced the breeding ecology of both sandpipers, with earlier nest initiations and lower nest survival rates in areas of high fox activity. ABSTRACT Understanding predator–prey interactions is crucial for correctly answering many fundamental ...

Ecology and Evolution, Volume 16, Issue 3, March 2026.Feather corticosterone (fCORT) provides a powerful indicator of population‐level physiological responses to human disturbance, yet its interpretation is complicated by variation across taxa, habitats, and molt‐movement strategies. Using stable isotope analyses to account for molt migrants in the globally endangered Scaly‐sided Merganser (Mergus ...
