Warmer and wetter winters: characteristics and implications of an extreme weather event in the High Arctic
One predicted consequence of global warming is an increased frequency of extreme weather events, such as heat waves, droughts, or heavy rainfalls. In parts of the Arctic, extreme warm spells andExpand

The importance of tidewater glaciers for marine mammals and seabirds in Svalbard, Norway
Abstract Approximately 60% of Svalbard's land areas are glaciated at the present time. The Archipelago has more than 1100 glaciers (> 1 km2) and 163 of these are “tidewater glaciers” — that isExpand

Diel vertical migration of Arctic zooplankton during the polar night
High-latitude environments show extreme seasonal variation in physical and biological variables. The classic paradigm of Arctic marine ecosystems holds that most biological processes slow down orExpand

Is the poleward expansion by Atlantic cod and haddock threatening native polar cod, Boreogadus saida?
During a recent period of increased influx of warm Atlantic water to the western coast of Svalbard, we have observed a northward expansion of boreal Atlantic cod (Gadus morhua) and haddockExpand

In the dark: A review of ecosystem processes during the Arctic polar night
Abstract Several recent lines of evidence indicate that the polar night is key to understanding Arctic marine ecosystems. First, the polar night is not a period void of biological activity evenExpand

Gender Specific Reproductive Strategies of an Arctic Key Species (Boreogadus saida) and Implications of Climate Change
The Arctic climate is changing at an unprecedented rate. What consequences this may have on the Arctic marine ecosystem depends to a large degree on how its species will respond both directly toExpand

Demographic effects of extreme weather events: snow storms, breeding success, and population growth rate in a long-lived Antarctic seabird
Weather extremes are one important element of ongoing climate change, but their impacts are poorly understood because they are, by definition, rare events. If the frequency and severity of extremeExpand

Seasonal ecology and life-history strategy of the high-latitude predatory zooplankter Parasagitta elegans
Organisms residing in seasonal environments schedule their activities to annual cycles in prey availability and predation risk. These cycles may be particularly pronounced in pelagic ecosystems ofExpand

Meta-ecosystems and biological energy transport from ocean to coast: the ecological importance of herring migration
Ecosystems are not closed, but receive resource subsidies from other ecosystems. Energy, material and organisms are moved between systems by physical vectors, but migrating animals also transportExpand

Copepod mating: chance or choice?
Mate choice is common in most animals, but the issue has largely been ignored in regard to pelagic copepods-the most abundant zooplankton group in the oceans. Contemporary demographic models ofExpand
