The junk-food hypothesis is that (for various reasons) predators switch from prey of high nutritional value to prey of low nutritional value. This switch
can lead to increased mortality and reduced breeding productivity in the predator species. The hypothesis has been linked to the decline and recovery of
common guillemot population in the Baltic Sea and the decline of seabird populations around the North Sea.
