Publikováno v: Fauna Norvegica, Vol 41 (2021)

The Arctic tadpole shrimp Lepidurus arcticus has a circumpolar distribution and the Scandes (Fennoscandian Mountains) marks its southernmost limit in Europe. Within this area, 391 natural and 88 regulated lakes with L. arcticus have been identified,

The freshwater shrimp Gammarus lacustris (Malacostraca, Amphipoda) in lakes on the Hardangervidda mountain plateau, southern Norway: distribution and environmental requirements

Autor: Tore Qvenild, Trygve Hesthagen, TH, Arne Fjellheim

Publikováno v: Fauna Norvegica, Vol 40 (2020)

The distribution of the amphipod Gammarus lacustris on the Hardangervidda mountain plateau was mapped by screening published data from 245 lakes in 11 and 16 catchments in western and central/eastern areas, respectively. These data are primarily base

Climatic effects on a cold stenotherm species Lepidurus arcticus (Branchiopoda, Notostraca) on the southern outreach of its distribution range

Autor: Tore Qvenild, Eirik Fjeld, Arne Fjellheim, Sigurd Rognerud, Åsmund Tysse

Publikováno v: Fauna Norvegica, Vol 38 (2018)

On the Norwegian mainland, the Arctic tadpole shrimp Lepidurus arcticus is a typically alpine species mainly co-occurring with fish. The Hardangervidda mountain plateau is the main area of the southernmost L. arcticus populations. Here L. arcticus is

Publikováno v: Ecological Indicators. 37:341-350

The WHAM-FTOX model uses chemical speciation to describe the bioavailability and toxicity of proton and metal mixtures (including Al) to aquatic organisms. Here, we apply the previously parameterised model to 45 UK and Norwegian upland surface waters
