Proc Natl Acad Sci U S A . 2024 May; 121(21):e2315513121. PMID: 38739784
Mercury (Hg) is a heterogeneously distributed toxicant affecting wildlife and human health. Yet, the spatial distribution of Hg remains poorly documented, especially in food webs, even though this knowledge is...

Chastel O, Fort J, Ackerman J, Albert C, Angelier F, Basu N, et al.
Sci Total Environ . 2022 Jun; 844:156944. PMID: 35752241
Since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of mercury (Hg) on Arctic biota in 2011 and 2018, there has been a considerable number...

Dietz R, Fort J, Sonne C, Albert C, Bustnes J, Christensen T, et al.
Environ Int . 2020 Nov; 146:106178. PMID: 33246245
A wide range of species, including marine mammals, seabirds, birds of prey, fish and bivalves, were investigated for potential population health risks resulting from contemporary (post 2000) mercury (Hg) exposure,...

Haarr A, Hylland K, Eckbo N, Gabrielsen G, Herzke D, Bustnes J, et al.
Environ Toxicol Chem . 2017 Nov; 37(4):1084-1091. PMID: 29120089
Environmental contaminants are found throughout Arctic marine ecosystems, and their presence in seabirds has been associated with toxicological responses. However, there are few studies of genotoxicity in Arctic avian wildlife....

Guery L, Descamps S, Pradel R, Hanssen S, Erikstad K, Gabrielsen G, et al.
J Anim Ecol . 2017 Jan; 86(3):683-693. PMID: 28127765
Understanding how individuals and populations respond to fluctuations in climatic conditions is critical to explain and anticipate changes in ecological systems. Most such studies focus on climate impacts on single...

Dabert M, Coulson S, Gwiazdowicz D, Moe B, Hanssen S, Biersma E, et al.
Exp Appl Acarol . 2014 Oct; 65(2):163-79. PMID: 25342243
Recent molecular phylogenetic analyses have revealed that some apparently oligoxenous feather mite species are in fact monoxenous cryptic species with little morphological differentiation. In this study we analyzed two species,...

Bourgeon S, Leat E, Magnusdottir E, Furness R, Strom H, Petersen A, et al.
PLoS One . 2014 Jun; 9(6):e100439. PMID: 24964085
Environmental conditions encountered by migratory seabirds in their wintering areas can shape their fitness. However, the underlying physiological mechanisms remain largely unknown as birds are relatively inaccessible during winter. To...

Hanssen S, Bustnes J, Schnug L, Bourgeon S, Johnsen T, Ballesteros M, et al.
Ecol Evol . 2014 Jan; 3(16):5157-66. PMID: 24455145
Parasites are natural stressors that may have multiple negative effects on their host as they usurp energy and nutrients and may lead to costly immune responses that may cause oxidative...

Moller A, Merino S, Soler J, Antonov A, Badas E, Calero-Torralbo M, et al.
PLoS One . 2014 Jan; 8(12):e82886. PMID: 24391725
Background: Climate change potentially has important effects on distribution, abundance, transmission and virulence of parasites in wild populations of animals. Methodology/principal Finding: Here we analyzed paired information on 89 parasite...
