Modeling the link between prey availability and diet: common murre--capelin interaction during the breeding season
This study explores the relationship between prey availability and predator's diet, using the common murre-capelin interaction as a case study. Data on prey availability and chick's diets were gathered synoptically during the breeding season. They were then integrated into three structural...
