Elementary Theory of Infra-Red Spectroscopyke the terrestrial ecosystem studies, however, relatively less effort has been made to elucidate possible effects of elevated CO. on wetland ecosystems. Although wetland ecosystems including peat-forming wetland cover only 2-6 % of global land surface (Gorham 1991), they play a pivotal role in globa

Patrick Saint-Dizier,Sharon J. Hamiltonctly the fluxes of CO. between the atmosphere and forest ecosystems. The main approach has been to use eddy covariance from towers above forest canopies to quantitatively evaluate the net ecosystem exchange of carbon dioxide over short periods (NEE). During the last five years many CO. flux towers h

Some of these features, such as patch isolation or contagion, are measures of the placement of patch types relative to other patch types, the landscape boundary, or other feat

Accordingly, there is an acute need for conservation and management of grassland biodiversity in these areas. Different g
