Circulating trace elements: Comparison between early and late incubation in common eiders (Somateria mollissima) in the central Baltic Sea
Mcpartland, Molly; Noori, Brenley; Garbus, Svend-Erik; Lierhagen, Syverin; Sonne, Christian; Krøkje, Åse (Peer reviewed; Journal article, 2020)We analyzed body mass and a panel of 64 trace elements in blood from incubating common eiders (Somateria mollissima) in the central Baltic Sea during the breeding seasons of 2017 (n = 27) and 2018 (n = 23). Using a ... -
Elemental content of brown crab (Cancer pagurus) - Is it safe for human consumption? A recent case study from Mausund, Norway
Ervik, Hilde; Lierhagen, Syverin; Asimakopoulos, Alexandros (Peer reviewed; Journal article, 2019)The brown crab (Cancer pagurus; the edible crab) is consumed worldwide and greatly appreciated for the essential elements (e.g., Zn, Se) that it contains. However, alongside these, it contains toxic elements that can pose ... -
Hair mineral levels as indicator of wildlife demographics?—a pilot study of muskoxen
Mosbacher, Jesper Bruun; Desforges, Jean-Pierre; Michelsen, Anders; Hansson, Sophia V.; Stelvig, Mikkel; Eulaers, Igor; Sonne, Christian; Dietz, Rune; Jenssen, Bjørn Munro; Ciesielski, Tomasz Maciej; Lierhagen, Syverin; Flaten, Trond Peder; Le Roux, Gael; Aggerbeck, Marie R.; Schmidt, Niels Martin (Peer reviewed; Journal article, 2022)The tight linkage between mineral status and health and demographics in animals is well documented. Mineral deficiencies have been coupled to population declines in wildlife. Current practices typically rely on liver, ... -
Lead concentrations in blood from incubating common eiders (Somateria mollissima) in the Baltic Sea.
Lam, Su Shiung; Mcpartland, Molly; Noori, Brenley; Garbus, Svend-Erik; Lierhagen, Syverin; Lyngs, Peter; Dietz, Rune; Therkildsen, Ole Roland; Christensen, Thomas Kjær; Tjørnløv, Rune Skjold; Kanstrup, Niels; Fox, Anthony D.; Sørensen, Iben Hove; Arzel, Céline; Krøkje, Åse; Sonne, Christian (Journal article; Peer reviewed, 2020)Here we investigate if lead may be a contributing factor to the observed population decline in a Baltic colony of incubating eiders (Somateria mollissima). Body mass and blood samples were obtained from 50 incubating female ... -
Lead isotopic signatures in blood from incubating common eiders (Somateria mollissima) in the central Baltic Sea
Mcpartland, Molly; Garbus, Svend-Erik; Lierhagen, Syverin; Sonne, Christian; Krøkje, Åse (Peer reviewed; Journal article, 2020)The Christiansø colony of common eiders (Somateria mollissima) in the central Baltic Sea were exposed to high levels of Pb during the 2018 breeding season that were not present in 2017. Due to these high Pb blood levels, ... -
