Long‐Term Changes in the Winter Diet of Common Dolphins Reflects Ecological Shifts and Bycatch Dynamics in the Bay of Biscay [PDF]
Ecology and Evolution, Volume 15, Issue 7, July 2025.First study investigating temporal changes in the diet of the common dolphin (Delphinus delphis) in the Bay of Biscay between 1999 and 2019, we found that the diet of the common dolphin remained mainly composed of small energy‐rich fish species. However, we observed a shift in minor prey from upper slopes habitats to coastal waters reflecting a shift ...
