Adverse foraging conditions may impact body mass and survival of a high Arctic seabird
Tradeoffs between current reproduction and future survival are widely recognized, but may only occur when food is limited: when foraging conditions are favorable, parents may be able to reproduce without compr...

Irreplaceable area extends marine conservation hotspot off Tunisia: insights from GPS-tracking Scopoli’s shearwaters from the largest seabird colony in the Mediterranean
Recent meta-analyses identified conservation hotpots at the scale of the Mediterranean, yet those may be crude by lack of detailed information about the spatial ecology of the species involved. Here, we ident...

Deciphering the structure of the West Greenland marine food web using stable isotopes (δ13C, δ15N)
The Arctic is facing major environmental changes impacting marine biodiversity and ecosystem functioning. One way of assessing the responses of an ecosystem to these changes is to quantitatively study food web...

Open AccessArctic climate change and pollution impact little auk foraging and fitness across a decade
Ongoing global changes apply drastic environmental forcing onto Arctic marine ecosystems, particularly through ocean warming, sea-ice shrinkage and enhanced pollution. To test impacts on arctic marine ecologic...

Open AccessArctic seabirds and shrinking sea ice: egg analyses reveal the importance of ice-derived resources
In the Arctic, sea-ice plays a central role in the functioning of marine food webs and its rapid shrinking has large effects on the biota. It is thus crucial to assess the importance of sea-ice and ice-derived...

Open AccessClimate change could overturn bird migration: Transarctic flights and high-latitude residency in a sea ice free Arctic
Climate models predict that by 2050 the Arctic Ocean will be sea ice free each summer. Removing this barrier between the Atlantic and the Pacific will modify a wide range of ecological processes, including bir...

No way home: collapse in northern gannet survival rates point to critical marine ecosystem perturbation
Seabirds are one of the most threatened of all bird groups, with a marked community-wide decline across the last decades. Yet, some seabird species are more resilient than others, and it is essential to study ...

Highly diversified habitats and resources influence habitat selection in wintering shorebirds
Habitat selection is an important process in birds that influences individual survival and fitness, and ultimately shapes population dynamics. As a consequence, strong selective pressures apply to favor strate...

Open AccessComplex population structure of the Atlantic puffin revealed by whole genome analyses
The factors underlying gene flow and genomic population structure in vagile seabirds are notoriously difficult to understand due to their complex ecology with diverse dispersal barriers and extensive periods a...

Habitat when foraging does not explain temporal segregation by sex in a breeding seabird
Segregation by sex can allow partitioning of resources in time, space, or both. Little, however, is known about causes of sexual segregation, especially in species with little to no sexual size dimorphism. Fem...

Small Space but High Diversity: Spatial and Temporal Habitat Use by Endangered Eurasian Curlew at Wintering Sites Throughout Europe
Coastal, and to a lesser extend inland wetlands, are critical habitats for wintering shorebirds. Given the significant population declines of most shorebird species worldwide, the current degradation of coasta...

Circumpolar assessment of mercury contamination: the Adélie penguin as a bioindicator of Antarctic marine ecosystems
Due to its persistence and potential ecological and health impacts, mercury (Hg) is a global pollutant of major concern that may reach high concentrations even in remote polar oceans. In contrast to the Arctic...

Open AccessKeystone seabird may face thermoregulatory challenges in a warming Arctic
Climate change affects the Arctic more than any other region, resulting in evolving weather, vanishing sea ice and altered biochemical cycling, which may increase biotic exposure to chemical pollution. We test...

Open AccessIntracolony variability in winter feeding and migration strategies of Atlantic puffins and black-legged kittiwakes
Polar ecosystems are subjected to many stressors, including climate change, that impact their overall functioning. Seabirds are good bioindicators of these systems as they readily respond to changes in environ...
