Biotic interactions mediate soil microbial feedbacks to climate change.
Decomposition of organic material by soil microbes generates an annual global release of 50-75 Pg carbon to the atmosphere, ∼7.5-9 times that of anthropogenic emissions worldwide. This process is sensitive to global change factors, which can drive carbon cycle-climate feedbacks with the potential to enhance atmospheric warming. Although the effects of interacting global change factors on soil m...
متن کاملBiotic feedbacks in Lake phosphorus cycles.
Limnologists are now reconsidering the role of the biota in the phosphorus (P) cycles of lakes. Changes in lake communities can have significant consequences for ecosystem P cycles. At seasonal timescales, the relative importance of nitrogen (N) and Pas limiting factors for primary production depends in part on zooplankton species composition. Phosphorus storage and recycling by fish and zoopla...
متن کاملAtmospheric chemistry‐climate feedbacks
[1] We extend the theory of climate feedbacks to include atmospheric chemistry. A change in temperature caused by a radiative forcing will include, in general, a contribution from the chemical change that is fed back into the climate system; likewise, the change in atmospheric burdens caused by a chemical forcing will include a contribution from the associated climate change that is fed back in...
متن کاملResponses and feedbacks of coupled biogeochemical cycles to climate change: examples from terrestrial ecosystems
© The Ecological Society of America www.frontiersinecology.org I an era of extensive environmental change, human activity – particularly the harvest of resources for food, fiber, and fuel – is substantially altering Earth’s climate and its element cycles (Vitousek et al. 1997; Figure 1). The need for energy to support economic growth has increased atmospheric carbon dioxide (CO2) concentrations...
متن کاملBiosphere feedbacks and climate change
POLICY ACTION ON CLIMATE CHANGE IS INFORMED BY CLIMATE MODEL projections as described most recently in the Fifth Assessment Report (AR5) of the Intergovernmental Panel on Climate Change (IPCC). The models used are general circulation models (GCMs), which numerically represent the physical climate system in three dimensions, including the hydrological cycle. These are complemented by recently de...
