Katerina Dontsova, Le Roux Gael, Zsuzsanna Balogh-Brunstad, and Pierret Marie-Claire invite you to submit abstracts to the 2016 Goldschmidt session "11e: Ecological Drivers of Biogeochemical Cycles Under Changing Environment" under Theme 11 Weathering and Erosion. Abstract submission is open now until February 26, 2016.
Keynote: Jon Chorover (University of Arizona)
Single biogeochemical processes are better and better known in the critical zone, however interactions and cascading effects between biogeochemical compartments and ecological actors are under-studied. For example, weathering processes are stronglyaffected by biota (microorganisms and plants), but it is difficult to quantify and predict the effect and the rates of biological weathering, because of its interdependence on plant growth and development, and on abiotic processes. This is even more difficult if ecosystems are subjected to climate shifts and management changes. To evaluate interdependencies between processes in critical zone, frontier ecosystems can be of particular interest due to their sensitivity to changes. This session invites presentations about biological and/or ecological effects on biogeochemical cycles and weathering on multiple scales with particular focus on the frontier critical zones such as mountainous, boreal or arctic areas. Studies of human impact with cascading loops (species introduction, forest management, local practices) are also welcome.
