Comparative host-parasite population structures: disentangling prospecting and dispersal in the black-legged kittiwake Rissa tridactyla.
Although much insight is to be gained through the comparison of the population genetic structures of parasites and hosts, there are, at present, few studies that take advantage of the information on vertebrate life histories available through the consideration of their parasites. Here, we examined the genetic structure of a colonial seabird, the black-legged kittiwake (Rissa tridactyla) using s...
متن کاملInterannual variation in the adrenal responsiveness of black-legged kittiwake chicks (Rissa tridactyla).
Over the last decade, field endocrinologists have explored the efficacy of using plasma corticosterone concentrations of breeding seabirds as an indicator of food availability and predictor of breeding success. However, studies have been predominately confined to adults and the results have been inconsistent. We examined the relationship between the productivity of black-legged kittiwakes (Riss...
متن کاملSeasonal interactions in the black-legged kittiwake, Rissa tridactyla: links between breeding performance and winter distribution.
Relationships between events in one period of the annual cycle and behaviour in subsequent seasons are key determinants of individual life histories and population dynamics. However, studying such associations is challenging, given the difficulties in following individuals across seasons, particularly in migratory species. Relationships between breeding performance and subsequent winter ecology...
متن کاملInterannual variability of Black-legged Kittiwake productivity is reflected in baseline plasma corticosterone.
Seabird productivity is shaped by marine resource availability. We examined the link between seabird productivity and an indirect measure of food availability: baseline plasma corticosterone. We predicted low productivity would coincide with elevated baseline corticosterone levels in Black-legged Kittiwakes (Rissa tridactyla). During a 5-year period of declining Kittiwake productivity in Chinia...
متن کاملLinking food availability, body growth and survival in the black-legged kittiwake Rissa tridactyla
Population dynamics of black-legged kittiwakes Rissa tridactyla in Bering Sea colonies are likely to increasingly experience climate-induced changes in the physical environment. Since adult kittiwakes are central place foragers with high energy requirements, increased variability of forage patch dynamics, as predicted for polar regions, may influence both quantity and quality of food available ...
