From winter time to summer time – what ends the "hunger gap" for Svalbard reindeer?

The term "hunger gap" (no: “vårknipa”) traditionally used in agricultural communities, refers to the period at the end of winter when winter provisions are depleting, yet the growing season has not yet started. In contemporary usage, the term also describes the food situation for wild animals, wh...

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...

Mercury dynamics in Arctic fjord marine food webs

Marine chemical pollution poses known threats to human health and to biodiversity, ecosystem and societal services. The Arctic region is a major sink of global mercury (Hg) pollution. Arctic sediments, sea and glacial ice constitute vast Hg reservoirs. Recent studies raise concerns about their ...

Intertidal ecosystem response to an increasingly ice-free Arctic

Warming temperatures and a reduction of sea-ice scour opens the Arctic intertidal as habitat for colonization by both seaweeds and marine invertebrates. Indeed, large increases in the biomass of seaweeds and invertebrates on Arctic coasts have already been documented in the past decades and are p...

Breeding phenology of Svalbard snow buntings in relation to arthropod abundance

In my master thesis, I will investigate the reproductive success of a Svalbard breeding population of the snow bunting Plectrophenax nivalis in relation to food abundance. The snow bunting is the world’s northernmost breeding passerine species. Assessing how species like the snow bunting are able...

Longterm consequences of one year of draining on biodiversity in Arctic ponds

In 2019, 19 ponds in Kongsfjorden were sampled, however, due to an extremely warm summer in 2020, 8 out of 19 completely dried out. In 2021 all ponds contained water again. We expect that due the high temperatures, increased evaporation and a deeper active layer have caused the desiccation. As cl...
