Dear Colleagues, We invite you to submit an abstract to our AGU session: B039 Impacts of vegetation change on biogeochemical and biophysical processes in arctic tundra ecosystems.
We are broadly interested in understanding both biochemical and biophysical feedbacks between vegetation and ecosystem function in high latitude ecosystems, using a variety of approaches. Session description: Arctic ecosystems are undergoing rapid change. Strong positive feedbacks to warming are possible in these ecosystems as carbon stored in permafrost soils is mobilized and evades to the atmosphere. However, vegetation is also changing and could alter biogeochemical cycling and biophysical processes in a way that offsets permafrost carbon release. Understanding how vegetation will alter biogeochemical cycling and biophysical processes as climate warms will allow better prediction of the future states of these ecosystems. Presentations are invited which use long term baseline studies, remote sensing, and process-level experiments to illustrate trends in vegetation and/or biogeochemical and biophysical feedbacks across different spatial and temporal scales, in order to enable prediction of future functional states of arctic ecosystems. This session will provide a forum for researchers to link tundra vegetation science via remote sensing, phenology, population- and ecosystem- ecology to address ecological dynamics in high-latitude ecosystems, and to promote collaboration. https://agu.confex.com/agu/fm17/preliminaryview.cgi/Session26795 Abstracts are due August 2, 2017 (early abstracts submitted by July 26 are eligible for a prize), and should be submitted on the AGU website: http://fallmeeting.agu.org/2017/abstract_overview/abstract-submissions/ We hope that you will join us! Sincerely, Conveners: Syndonia Bret-Harte, University of Alaska Fairbanks, and Michelle Mack, Northern Arizona University
