Variation in food availability affects the population age structure of Atlantic puffins Fratercula arctica in the Faroe Islands
Across their entire Atlantic breeding range, Atlantic puffins Fratercula arctica have experienced decreases in food availability, often leading to population declines. The species is one of the most ....
