Combined bottom-up and top-down pressures drive catastrophic population declines of Arctic skuas in Scotland

Understanding drivers of population change is critical for effective species conservation. In the northeast Atlantic Ocean, recent changes amongst seabird communities are linked to human and climate change impacts on food webs. Many species have declined severely, with food shortages, and...
