The global importance of grasslands is indicated by their extent; they comprise some 26% of total land area and 80% of agriculturally productive land. The majority of grasslands are located in tropical developing countries where they are particularly important to the livelihoods of some one billion poor peoples. Grasslands clearly provide the feed base for grazing livestock and thus numerous hi...

Cycling of water quality constituents in lakes is affected by thermal stratification and homo-thermal conditions other factors such as oligotrophication, eutrophication, microbial activities. In addition, hydrological variability can cause greater differences residence time cycling man-made (reservoirs) than natural lakes. Thus, investigations are needed on vertical mixing new impounded reservo...

Species diversity has declined in ecosystems worldwide as a result of habitat fragmentation, eutrophication, and land-use change. If such decline is to be halted ecological mechanisms that restore or maintain biodiversity are needed. Two long-term field experiments were performed in native grassland to assess the effects of fire, nitrogen addition, and grazing or mowing on plant species diversi...

Yellow starthistle (Centaurea solstitialis L.) is a summer-flowering annual plant of the family Asteraceae, and a significant weed of roadsides, pasture and grasslands in California. It is also distributed, though with less economic and ecological significance, throughout the US and in other temperate parts of the world. Yellow starthistle grows vigorously during the dormant period for most nat...

the effects of dominant shrub species on soil organic matter (som), including total soil carbon (sc), total nitrogen (n) and particulate organic matter (pom) were studied in three stands differing in the type of shrub species, i.e. astragalus microcephalus (shrub), pteropyrum aucheri (shrub) and prangus uloptera (non-shrub).the stands were located in arid grasslands of north-western iran. for t...
