Microbial Populations of Arid Lands and their Potential for Restoration of Deserts
نویسندگان
چکیده
The rapid expansion of deserts in recent decades as a result of human actions combined with climatic disasters has highlighted the necessity to understand biological processes in arid environments. Whereas physical processes and the biology of flora and fauna have been relatively well studied in marginally used arid areas, knowledge of desert soil micro-organisms remains fragmentary. This chapter describes several biological phenomena in hot deserts related to microbial populations and the potential use of micro-organisms for restoring hot desert environments. A few relevant examples from colder deserts are also provided.

متن کاملClimate Change and Ecosystems of the Southwestern United States By Steven
Arid desert ecosystems of the western United States are particularly susceptible to climate change and climate variability. Plants and animals in this region live near their physiological limits for water and temperature stress. Slight changes in temperature or precipitation regimes or a change in the frequency and magnitude of extreme climatic events could therefore substantially alter the com...
