Biodiversity survey of the UNESCO Sheka forest biosphere reserve from Februar...
Data of amphibians, reptiles and birds surveyed from February 2016 to May 2016 in the UNESCO Sheka forest biosphere reserve are provided as an online open access data file. This... -
Thermal measurements on sub-Antarctic megaherbs and environmental characteris...
We evaluated whether heating occurs in sub-Antarctic megaherbs, and the relation of heating to relevant environmental variables. We measured leaf and inflorescence temperature... -
Establishment, expansion and regeneration of aspen (Populus tremula) in the T...
In subarctic Sweden, recent decadal colonization and expansion of aspen (Populus tremula L.) were recorded. Over the past 100 years, aspen became c. 16 times more abundant,... -
Biometrics, fatty acid composition and stable isotopic ratios of five seabird...
Marine birds are important predators in the marine ecosystem, and dietary studies can give useful information about their feeding ecology, food webs and oceanographic... -
Thyroid hormones and halogenated organic compounds in black-legged kittiwake ...
Thyroid hormones are essential for normal growth and development and disruption of thyroid homeostasis can be critical to young developing individuals. The aim of the present... -
Concentrations of brominated and chlorinated contaminants in adipose tissue o...
Adipose tissue was sampled from the western Hudson Bay (WHB) subpopulation of polar bears at intervals from 1991 to 2007 to examine temporal trends of PCB and OCP levels both on... -
Characteristics and stomach contents of Greenland sharks (Somniosus microceph...
Harbour seals in Svalbard have short longevity, despite being protected from human hunting and having limited terrestrial predation at their haulout sites, low contaminant... -
Concentrations of persistant organic pollutants in Great skua eggs (Stercorar...
Concentrations of POPs in Great skua eggs from Shetland are among the highest in North Atlantic seabirds, with up to 11,600 µg/kg (ww) DDE and up to 17,900 µg/kg ww SumPCB.... -
Whale sightings, group sizes and krill biomass in West Greenland in 2005
This study combined data on fin whale Balaenoptera physalus, humpback whale Megaptera novaeangliae, minke whale B. acutorostrata, and sei whale B. borealis sightings from... -
Thyroid hormone and gland status of Greenland sledge dogs (Canis lupus famili...
As a model of high trophic level carnivores, sledge dogs were fed from 2 to 18 months of age with minke whale blubber containing organohalogen compounds (OHC) corresponding to... -
Age, body mass, mass change and dispersal distance of suckling and weaned gre...
Grey seal, Halichoerus grypus, pups in the breeding colony at Froan, Norway, have a bimodal pattern of early aquatic behaviour. About 40% of the pups spend their time ashore to... -
Rates of seropositivity for Toxoplasma gondii antibodies in polar bears and m...
Little is known about the prevalence of the parasite Toxoplasma gondii in the arctic marine food chain of Svalbard, Norway. In this study, plasma samples were analyzed for T.... -
Enzyme activity and liver tissue PCB concentrations of chicks of northern ful...
Arctic seabirds are exposed to a wide range of halogenated organic contaminants (HOCs). Exposure occurs mainly through food intake, and many pollutants accumulate in lipid-rich... -
Persistent organic pollutants, δ¹³C and d15N in zooplankton, fish and bird sp...
Seasonality in biomagnification of persistent organic pollutants (POPs; polychlorinated biphenyls, chlorinated pesticides, and brominated flame retardants) in Arctic marine... -
Isotopic composition of diet and tissues, and isotope discrimination factors ...
Breeding in the high Arctic is time constrained and animals should therefore start with their annual reproduction as early as possible. To allow for such early reproduction in... -
Fork lengths, stomach contents and parasites of ninespine stickleback and arc...
Stable d13C and d15N isotopes, diet and parasites demonstrated that the prey consumed by ninespine stickleback Pungitius pungitius in a small lake on Baffin Island changed... -
Concentrations of PBDE and BDE congeners in adipose tissue of East Greenland ...
Polybrominated diphenyl ethers (PBDEs) were analysed in adipose tissue from 92 East Greenland polar bears (Ursus maritimus) sampled during 1999-2001. Mean SumPBDE concentrations... -
Mercury content and isotopic composition of teeth, and sex and age of skulls ...
We examined the use of mercury (Hg) and nitrogen and carbon stable isotopes in teeth of polar bear (Ursus maritimus) from Svalbard as biotracers of temporal changes in Hg...
