B53F:
The Fate of Carbon in Plants and Terrestrial Ecosystems: From Respiration to Allocation II Posters

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#: 12815

Session Description:
Carbon assimilated by plants in photosynthesis can be respired in the plants leaves, stems or roots, or by heterotrophic respiration in the soil. This respired carbon is usually lost from the ecosystem, while the remaining carbon can be allocated to growth, to roots exhudates, or to non-structural carbon reserves.

The fate of carbon assimilated by plants determines the rates of carbon sequestration, and strongly affects the plants and ecosystem resilience to environmental stress. However, we still lack a comprehensive understanding of:

1)      What drives the rate of plant and soil respiration?

2)      Is all respired carbon lost from the ecosystem, or is some of it recycled within it?

3)       What determines the allocation of nonstructural carbon to growth, metabolism and storage?

4)       How do respiration and allocation patterns change under changing environmental conditions and what are the consequences for biogeochemical cycles?

Contributions from observational, experimental and modelling studies, are invited.
