The role of cultivated versus wild seeds in the diet of European turtle doves (Streptopelia turtur) across European breeding and African wintering grounds

open access: yesEnvironmental DNA, Volume 6, Issue 2, March–April 2024.
Using metabarcoding, we analyze the diet of the European turtle dove (Streptopelia turtur) in different sites, both breeding and wintering. We identified a diverse range of taxa in the diet and little overlap in the food consumed in breeding and wintering grounds. The roles of wild and cultivated food in the diet and implications for species management

Occupancy trends of overwintering coastal waterbird communities reveal guild‐specific patterns of redistribution and shifting reliance on existing protected areas

open access: yesGlobal Change Biology, Volume 30, Issue 2, February 2024.
We evaluated 20‐year occupancy trends of coastal waterbirds wintering inside and outside protected areas (PAs) along Canada's Pacific coast. Occupancy declines were the greatest in older PAs concentrated at lower latitudes, with cold‐tolerant, migratory benthivores and piscivores shifting farther north or to cold‐water fjords.
