Distribution and population characteristics of the soil mites Diapterobates notatus and Svalbardia paludicola (Acari: Oribatida: Ceratozetidae) in High Arctic Svalbard (Norway)
(Journal article; Peer reviewed, 2017)The Oribatida of High Arctic Svalbard are faunistically relatively well known, but the distribution, density, stage structure and other population parameters of most species are unknown. Here we focus on two ceratozetid ... -
Feasibility and knowledge gaps to modeling circumpolar seabird bycatch in the Arctic
(Peer reviewed; Journal article, 2024)Alteration and diminution in sea ice cover in the Arctic region will give rise to an intensifcation and expansion of fishing activities in the Arctic and associated marginal seas. Increased fshing activity, especially in ... -
Mysis segerstralei, an unexpected but important prey for resident Arctic charr (Salvelinus alpinus) in a Svalbard lake
(Peer reviewed; Journal article, 2024)Mysis segerstralei is distributed over a wide geographic area and in habitats with a variety of salinity conditions, including marine and brackish waters around Svalbard. The species has seldom been found in freshwater ... -
Ocean currents as a potential dispersal pathway for Antarctica’s most persistent non-native terrestrial insect

Predictors of invertebrate biomass and rate of advancement of invertebrate phenology across eight sites in the North American Arctic
(Peer reviewed; Journal article, 2021)Average annual temperatures in the Arctic increased by 2–3 °C during the second half of the twentieth century. Because shorebirds initiate northward migration to Arctic nesting sites based on cues at distant wintering ... -
Spatial distribution in Norwegian lemming Lemmus lemmus in relation to the phase of the cycle
(Peer reviewed; Journal article, 2018)Competition between individuals of the same or different species affects spatial distribution of organisms at any given time. Consequently, a species geographical distribution is related to population dynamics through ... -
Wild Mountain reindeer Rangifer tarandus tarandus winter foraging: snow-free areas a key resource for feeding
(Peer reviewed; Journal article, 2023)In a landscape with patchily distributed forage resources, an animal’s distribution may reflect the distribution of the resources if the population is forage-limited in time or space. This may be particularly explicit in ...
