Synopses & Reviews
Nitrogen is a key element in ecosystem processes. Aspects of local and global changes in nitrogen in both undisturbed and disturbed conditions are discussed. Environmental changes caused by pollution from nitrogenous compounds and changes in landuse are also described. Organisms, plants, animals and microorganisms are all affecting nitrogen supply. Emphasis is placed on natural and anthropogenic transfer of nitrogen between ecosystems and also on the interaction of nitrogen with other bioelements.
Nitrogen supply is one of the most important growth-regulating factors in ecosystems. Anthropogenic emissions and other human activities are changing local, regional and global nitrogen cycles. The author discusses how land ecosystems with their organisms, plants, animals and microorganisms are affected by changes in nitrogen supply and how organisms influence nitrogen cycling in natural and polluted ecosystems.
