Climate change May Cause The Micro Organisms

“It really does look like microbes are sensitive to global changes. We are just not quite sure how they will respond,”
Breaking news from the world of global warm and climate change dated to the new day. The scientists warns on the forced biological diversity that comes with the global problem. Global warming and climate change may also impact the microscopic organisms, fungi and other microbial populations that support our life on Earth.
“Microbes perform a number of critical functions for ecosystems … we are only starting to understand the impact that global climate change is having on them,” were the words of Kathleen Treseder of the University of California.
Kathleen Treseder studied the effect of rising temperatures and fungi on carbon stores in Alaskan boreal forests, one area of the globe that is experiencing greater warming than others.
“There is a lot of frozen dead material under the snow pack. There is as much carbon trapped in the soil of northern ecosystems as there is carbon in the atmosphere. It is a big unknown what is going to happen if these environments heat up,” said Treseder.
Her research has been started with the hypothesis that an increase in temperatures would lead to increased decomposition by fungi and micro organisms and since one by-product of decomposition is carbon dioxide, rising temperatures should result in its greater release from the soil. What she found was that nitrogen levels in the soil increased as temperatures rose, which tends to suppress fungal decomposition rates.
