Abstract :
Soil microorganisms have important role at production and consumption of greenhouse gases,such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and nitric oxide (NO). On theother hand, there are valid reasons that climate changes can directly or indirectly alter the compositionand abundance of soil microbial communities. So that, the results of the systematic review showed thatthe main direct effects of climate changes on soil microbial communities are likely to be caused bychanges in temperature and moisture content. Howevr, the effects of increased CO2 levels onmicrobial communities are often indirect, as they are mediated by positive effects of the gas on plantphotosynthesis, which in turn changes in quantity and quality of soil C inputs. Any way, depending onthe taxonomy, body size, feeding habits, ecosystem type, local climate, treatment magnitude andduration, the patterns respons of the soil organisms in against of climate change parameters are differ.So that, the results of meta-analysis has show that the response of soil biota to elevated CO2, is dependon the trophic group, body size, and experimental approaches (field or greenhouse). Whereas, theresponse of soil biota to warming and altered precipitation are depend on local climate and ecosystemtype. Furthermore, the effects of increase CO2 on soil organism abundance diminished with time,however the effects of warming and altered precipitation intensified with time
