OOS-34: Incorporating ecological processes at many scales into biogeochemical and
global climate change models
Wednesday,
August 10, 1:30 PM - 5 PM, Meeting Rooms 510b and 510d, Level 5, Palais
des congrès de Montréal
Organizers:
Wilfred Post (postwmiii@ornl.gov),
Jerry Olson, Changhui Peng
Description:
Terrestrial
feedbacks to the climate system vary significantly at decade to century time
scale through disturbances such vegetation alteration, invasive species, altered
fire regimes, large-scale insect outbreaks, nitrogen deposition, succession,
competitive interaction, herbivore cycles, and soil development. Ecological
processes, especially at decade and century time scales, are not sufficiently
represented in regional or terrestrial global climate models. Incorporation of
process based ecological representations of population and community dynamics
and impacts on climate processes at various temporal scales, represents a
challenging new direction where ecologist can significantly contribute to global
climate change research. This organized oral session presents emerging concepts
and algorithms needed to model the impact of population, community, and
ecosystem processes on climate dynamics, inform ecologists of the development of
next generation global change models, in order to engage ecologists in
development of concepts and algorithms that represent terrestrial feedbacks to
global climate change.
