Grasslands of the World: Diversity, Management and Conservation

Features provide a comprehensive global overview of extent and diversity of grasslands. Analyzes how humans shaped grasslands through millennia of use and which role they play in present-day agriculture. Quantifies the role of grasslands as biodiversity hotspots as well as the drivers threatening these. Evaluates the ecosystem services grasslands provide e.g. in terms of soil protection and car...

Functioning in Grasslands

Grasslands are the potential natural ecosystem type on approximately 25% (33x lo6 km2) of the land surface of the earth (Shantz 1954). Current estimates of the global extent of grasslands range from 16% (Whittaker and Likens 1973, 1975) to 30% (Ajtay et al. 1979). The difference between the estimates of the potential extent of grasslands and the current extent provides an indication of the degr...

49624 NZ Grasslands Association.pmd

Although plant roots take up nitrogen (N) both as ammonium (NH 4 ) and nitrate (NO 3 ) ions, under most soil conditions uptake of NO 3 dominates. Once absorbed by the plant roots, the NO 3 is reduced to NH 4 , which is subsequently assimilated into organic compounds. However, when the ra te of uptake exceeds the rate of NO 3 reduction, accumulation of NO 3 in plants occurs. Ruminant animals wit...

Ecoregions of Canada’s Prairie Grasslands

The Central Plains of Western Canada comprise the Prairies Ecozone and the Boreal Plains Ecozone. The former has the most grasslands and is divided into seven ecoregions: Mixed Grassland, Cypress Upland, Moist Mixed Grassland, and Fescue Grassland in southern Alberta and Saskatchewan; Aspen Parkland, which extends in an arc from central Alberta and Saskatchewan southeast to southwestern Manitob...
