Microclimatic challenges in global change biology.

abstract：:In rice cultivation, there are controversial reports on net impacts of nitrogen (N) fertilizers on methane (CH 4 ) emissions. Nitrogen fertilizers increase crop growth as well as alter CH 4 producing (Methanogens) and consuming (Methanotrophs) microbes, and thereby produce complex effects on CH 4 emissions. Objectives...

abstract：:Several temperate tree species are expected to migrate northward and colonize boreal forests in response to climate change. Tree migrations could lead to transitions in forest types, but these could be influenced by several non-climatic factors, such as disturbances and soil conditions. We analysed over 10,000 forest ...
