HE34C:
Ecosystem Structure and Processes in a Changing Arctic IV Posters

Session ID#: 92333

Session Description:
The rate of atmospheric warming in the Arctic is outpacing that of other regions, and is associated with sea ice loss, warming ocean temperatures, changes in the hydrological cycle, and impacted ecosystems. Temperature-growth relations, nutrient cycling dynamics, altered seasonality, changing freshwater balances, expanded and contracted species range extensions, and new trophic pathways may each affect biodiversity, the population status of key species, and relations between humans and marine resources. As environmental change continues, can we anticipate how future Arctic ecosystems will compare to those of the past and present? Will the effects of a changing climate be the same across various Arctic regions? Organizers welcome presentations from all regions of the Arctic examining the drivers, rates, processes, and mechanistic controls that impart structure on any aspect of the high-latitude marine ecosystem.
