Responses of Arctic Planktonic Communities to Climate Change and the Impacts on Ecosystem Function

Session ID#: 257875

Session Description:
The Arctic is changing at an unprecedented pace with warming, sea ice melt, and shifting biogeochemical cycles. At the base of marine food webs, local planktonic communities are affected by these changes, with consequences for biodiversity and ecosystem function. 

There is therefore an urgent need to improve our understanding of the impacts that climate change will have on Arctic planktonic communities, including  phyto-, mixo-, and zooplankton components, as well as interactions between them (e.g., grazing and competition). This must be considered in the context of different environmental stressors (e.g., temperature, nutrient availability, and light) and on different timescales (i.e., acclimation vs. adaptation).  Such understanding can be used to identify ecological indicators of climate change and tipping points, as well as improving predictions for potential invasion of boreal species and harmful algae. This is especially pertinent, due to a strong economic reliance on marine ecosystem services in the Arctic region.

This session seeks to bring together researchers applying experiments, in situ observational data, and molecular methods, to improve understanding of Arctic plankton responses to climate change. We particularly welcome contributions from disciplines that use novel methods to study stressors of Arctic plankton, and that aim to advance parameterization of plankton models.
