Abstract:
Climate-change induced alterations of the organic matter flow from various primary production sources to the benthic system in the Arctic Chukchi Sea could have major implications on carbon cycling, sequestration, and benthic food web structure sustaining upper trophic levels.The goal of this study was to determine the proportional contributions of organic matter sources to marine sediments and to what degree these are being utilized by benthic invertebrates.
Bio:
Ann defended her PhD in Marine Biology at the University of Alaska Fairbanks focusing on organic matter source contribution to lower trophic level food webs, with a specific interest in terrestrial and bacterial organic matter. Her research focused on determining how different organic matter sources are represented in marine sediments and utilized by benthic invertebrates to then update a current Chukchi Sea ecosystem model.
