Food abundance, kittiwake life histories, and colony dynamics in the Northeastern Pacific:implications of climate change and regime shifts
Black-legged kittiwakes Rissa tridactyla in the Northeastern Pacific will increasingly experience climate-induced changes in the variability of forage fish, which will influence both the quantity and quality of food and may thus alter the population dynamics of kittiwake colonies. However, the relat...
