Habitat determines plant community responses to climate change in the High Arctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-12)Plant climate responses may depend on site-specific environmental context. Using fences and open-top chambers, we enhanced snow depth (creating Ambient, Medium, and Deep regimes) over an 11-year period and increased temperatures for two summers in dry heath and mesic meadow habitats on Svalbard, Norway. Comparison of plant growth form abundance and diversity responses in these two habitats showed ... -
Habitat selection by a marine copepod during the productive season in the Subarctic
(Journal article; Tidsskriftartikkel; Peer reviewed, 2010-10-14)Few studies have analysed the depth distribution of marine zooplankton at high-resolution, and knowledge obtained from theoretical modelling studies predominates over that from empirical field studies. We analysed depth selection by the marine copepod Calanus finmarchicus during spring and summer in neritic and oceanic Subarctic regions. Data on hydrography and zooplankton distribution in the upper ... -
