This indicates that our findings offer insights into the mechanisms behind strengthening terrestrial biotic feedbacks on the geochemical carbon cycle associated with evolutionary advancement of trees and mycorrhizal fungi.
Some models predict and research support that global change driven changes in plant community composition may be more important to regional terrestrial productivity and its feedback to the climate than will physiological responses of individual plant taxa [1], [2], [3].
Understanding feedbacks between terrestrial and atmospheric systems is vital for predicting the consequences of global change, particularly in the rapidly changing Arctic.
Soil is central in the terrestrial ecosystem, linking and providing feedback responses to the other components, i.e., water, atmosphere, and vegetation.
Interest in fire research has become global and interdisciplinary due to influences, interactions, and feedbacks among fire, terrestrial, and atmospheric systems in the context of human health [4], climate dynamics [5], and policy adaptation [6].
Since plants form the basis of terrestrial ecosystems, their behavioural interactions, feedbacks and influences are important in generating the emergent properties of ecosystems (Levin 2005).
Essentially, Etheridge and his colleagues have found that the Earth's terrestrial biosphere acts as a "positive feedback" in the climate system as global warming continues.
Atmospheric dust plays many important roles, such as neutralizing acid rain, delivering nutrients to marine and terrestrial ecosystems, and acting in complex feedbacks with incoming and outgoing radiation.
