Journal ArticleDOI
Negligible Impact of Ingested Microplastics on Tissue Concentrations of Persistent Organic Pollutants in Northern Fulmars off Coastal Norway
Dorte Herzke,Tycho Anker-Nilssen,Therese Haugdahl Nøst,Arntraut Götsch,Signe Christensen-Dalsgaard,Magdalene Langset,Kirstin Fangel,Albert A. Koelmans +7 more
TL;DR: It is shown that plastic is more likely to act as a passive sampler than as a vector of POPs, thus reflecting the POP profiles of simultaneously ingested prey.
Journal ArticleDOI

TL;DR: In this paper, the authors tracked adults from colonies throughout the Atlantic range over the non-breeding season using light-based geolocation, and estimated the size and composition of wintering populations using information on breeding population size.
Journal ArticleDOI

TL;DR: A comprehensive meta-analysis of 209 phenological time series from 145 breeding populations shows that, on average, seabird populations worldwide have not adjusted their breeding seasons over time or in response to sea surface temperature between 1952 and 2015.
Journal ArticleDOI
When things go wrong: intra‐season dynamics of breeding failure in a seabird
Aurore Ponchon,David Grémillet,David Grémillet,Signe Christensen-Dalsgaard,Kjell Einar Erikstad,Kjell Einar Erikstad,Robert T. Barrett,Tone Kristin Reiertsen,Karen D. McCoy,Torkild Tveraa,Thierry Boulinier +10 more
TL;DR: This integrative study confirms that breeding failure is a non-linear process characterized by a threshold beyond which individuals face an energetic trade-off and cannot simultaneously sustain high reproductive and self- maintenance efforts.
Journal ArticleDOI
Accuracy and precision in estimation of age of Norwegian Arctic polar bears ( Ursus maritimus ) using dental cementum layers from known-age individuals
TL;DR: It is concluded that age estimation of polar bears can be difficult, particularly in populations where individuals may forage throughout the year, and as different laboratories may read the same slides according to different criteria, an evaluation of the methods should be conducted for all populations.
