Evapotranspiration from Northern Semiarid Grasslands
Proper grazing management reduces ET from grasslands by reducing transpiration losses and grazingManagement of forage production for livestock grazing on semiarid induced surface energy relationships that reduce evapograsslands depends on water availability. Evapotranspiration (ET) ration (Svejcar and Christiansen, 1987; Wraith et al., was measured using the Bowen ratio energy balance method on...
متن کاملPost-fire runoff and erosion from rainfall simulation: contrasting forests with shrublands and grasslands
Rainfall simulations allow for controlled comparisons of runoff and erosion among ecosystems and land cover conditions. Runoff and erosion can increase greatly following fire, yet there are few rainfall simulation studies for post-fire plots, particularly after severe fire in semiarid forest. We conducted rainfall simulations shortly after a severe fire (Cerro Grande) in ponderosa pine forest n...
متن کاملBreeding biology of Henslow’s Sparrows on reclaimed coal mine grasslands in Kentucky
Populations of Henslow’s Sparrows (Ammodramus henslowii) are declining, and loss of habitat is a likely factor. Coal mine reclamation has created grassland habitat in Kentucky and elsewhere, and information is needed concerning the use of these areas by Henslow’s Sparrows. We compared the behavior and ecology of populations on reclaimed sites and non-mined sites in west-central Kentucky during ...
متن کاملFunctioning 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...
متن کامل49624 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...
