The role of energy budget in a changing world: Are forecasts missing an important aspect for Arctic insects?

The ongoing climatic changes will have undisputable effects on biodiversity and ecosystems. For small ectotherms (e.g. insects) the current state-of-the-art focusses on physiological performances (often measured as critical thermal limits), warming tolerance (resilience) and phenotypic and evolut...

Hiding in the shadows: effects of environmental stressors on male calanoid copepods - An insider's view

Polar ecosystems are particularly vulnerable to effects caused by environmental stressors of anthropogenic origin, such as ocean acidification (OA) and ocean warming (OW), both of which are disproportionally affecting the Arctic region. Calanoid copepods of the genus Calanus are key species in th...

Stress-coping strategies in a changing world: how do ground-nesting birds adapt to unpredictive predation threat?

In the Arctic, polar bears (Ursus maritimus) rely on sea ice to hunt seals. However, sea ice is decreasing due to climate warming, and bears are changing their foraging behavior, increasing egg consumption. This shift in diet can put ground-nesting bird species, such as common eiders (Somateria m...

Do snowshoes influence movement and route choice of Svalbard rock ptarmigan over snowy ground? (RiS ID 11821)

We are aiming to determine how changes in snow properties influence the function of a key adaptation for Arctic animals - the evolution of a snowshoe foot. Whilst increases in foot area are well known to provide extra support during movement over snow there is currently no data examining the rela...
