Dear colleagues, We want to call your attention to and encourage abstract submissions to the following session on Biota and Biogeochemical Cycling in Terrestrial and Aquatic Ecosystems in the Arctic at the 2016 American Geophysical Union Fall Meeting in San Francisco, California this December. Abstracts are due on August 3, which is coming right up. We look forward to seeing you there!
B020: Biota and Biogeochemical Feedbacks in Terrestrial and Aquatic Ecosystems in Arctic Alaska Session ID#: 13732 Session Description: Arctic ecosystems are undergoing rapid change as climate warms and disturbance regimes are altered. Strong positive feedbacks to warming are possible in these ecosystems as carbon stored in permafrost soils is mobilized and evades to the atmosphere. Changing seasonality may disrupt linkages among existing biotic and abiotic components and induce further change. Understanding how feedbacks between biota and biogeochemical cycling rates are likely to alter as climate warms and disturbance regimes change will allow better prediction of the future states of these ecosystems. Presentations are invited which use long term baseline studies and process-level experiments on multiple spatial and temporal scales to illustrate current state and trends in biota and/or biogeochemical cycling rates, in order to enable prediction of future functional states of arctic ecosystems. This session will enable synergies and future collaborations by highlighting research that addresses dependencies among terrestrial and aquatic systems of the Alaskan Arctic.
