HE44A:
Linkages Between Environmental Drivers and Structure of Arctic Ecosystems I Posters


Session ID#: 28705

Session Description:
Arctic ecosystems are adjusting to rapidly warming temperatures, sea ice loss and a myriad of other factors that are changing with time. Temperature-growth relations, altered seasonality, expanded and contracted range extents, and new trophic pathways may each affect biodiversity, 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 yesterday and today? Will the effects of a changing climate be the same across various Arctic regions? We welcome presentations from all regions of the Arctic examining rates, processes and mechanistic controls that impart structure on any aspect of the high-latitude marine ecosystem.
