B32B:
Plant Traits and Biogeochemical Cycles II

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 15447

Session Description:
Plant traits extend the range of earth observations to the level of individual organisms, providing a link to ecosystem function and modeling in the context of rapid global changes. However, overcoming the differences in temporal and spatial scales between plant trait data and biogeochemical cycles remains a challenge. This session will address the role of plant species, biodiversity and adaptation / acclimation in the biogeochemical cycles of water, carbon, nitrogen and phosphorus. We welcome conceptual, observational, experimental and modeling approaches, and studies from the local to the global scale, including e.g remote sensing observations.
