The stress hormone corticosterone in a marine top predator reflects short-term changes in food availability
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015)
In many seabird studies, single annual proxies of prey abundance have been used to explain variability in breeding performance, but much more important is probably the timing of prey availability relative to the breeding ...
There is more to climate than the North Atlantic Oscillation: a new perspective from climate dynamics to explain the variability in population growth rates of a long-lived seabird
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-29)
Predicting the impact of global climate change on the biosphere has become one of the most important efforts in ecology. Ecosystems worldwide are changing rapidly as a consequence of global warming, yet our understanding ...
Modelled drift patterns of fish larvae link coastal morphology to seabird colony distribution
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-13)
Colonial breeding is an evolutionary puzzle, as the benefits of breeding in high densities are still not fully explained. Although the dynamics of existing colonies are increasingly understood, few studies have addressed ...
Prey density in non-breeding areas affects adult survival of black-legged kittiwakes Rissa tridactyla
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-08-27)
In migratory birds, environmental conditions in both breeding and non-breeding areas may affect adult survival rates and hence be significant drivers of demographic processes. In seabirds, poor knowledge of their true ...
The decline of Norwegian kittiwake populations: modelling the role of ocean warming.
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
The black-legged kittiwake Rissa tridactyla is a pelagic seabird whose population has recently declined in most parts of the North Atlantic and which is red-listed in most bordering countries. To investigate a possible ...
Climate-Driven Ichthyoplankton Drift Model Predicts Growth of Top Predator Young
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013-11-12)
Climate variability influences seabird population dynamics in several ways including access to prey near colonies during the critical chick-rearing period. This study addresses breeding success in a Barents Sea colony of ...
