The ability of grassland ecosystems to sequester carbon has a great potential achieve neutralization. Rhizosphere deposition is the most uncertain part soil cycle. Since grazing one main ways utilize grasslands, we conducted experiments clarify role rhizosphere on organic (SOC) cycling under in typical steppe region Inner Mongolia, China. experiment was grasslands light, moderate, and heavy con...

In grazed habitats is a tradeoff between competition (decreases with the grazing intensity) and disturbance (increases). This may give tradeoffs between plant life stages. The seed production can be assumed to decrease at high disturbance intensities because of herbivory of reproductive organs, but also at high levels of competition (low grazing intensity) because of resource limitation. The es...

Grazing stimulates root and forage mass of perennial pastures, but few studies have addressed the effects grazing on annual pastures which are often grown in short periods within integrated crop–livestock systems (ICLS). In these N fertilization is a common practice to increase mass, its morphology unclear. field experiment, we evaluated how intensities (ungrazed, moderate, heavy grazing) rates...

Abstract Bahiagrass ( Paspalum notatum Flüggé) is a rhizomatous, perennial, warm‐season forage widely grown in the southeastern United States "UF Riata" bahiagrass more upright growing with greater herbage production when days are shorter compared most other cultivars. Lesser daylength sensitivity extends grazing season, but combination growth may negatively affect persistence under grazing, es...

According to the nonequilibrium theory, livestock grazing has a limited effect on long-term vegetation productivity of semiarid rangelands, which is largely determined by rainfall. The communal lands in northeastern South Africa contain extensive degraded areas which have been mapped by the National Land Cover (NLC) program. Much evidence suggests that long-term heavy grazing is the cause of th...

Grazing transits present a special problem for statistical studies of exoplanets. Even though grazing planetary orbits are rare (due to geometric selection effects), many low moderate signal-to-noise cases, significant fraction the posterior distribution is nonetheless consistent with geometry. A failure accurately model can therefore lead biased inferences even cases where planet not actually ...

Browse and cereal stubble represent the two most important resources for grazing small ruminants in dry Mediterranean areas. The purpose of the present review is to provide updated information regarding their nutritional value. In a mixed Mediterranean environment, browse represents at least 40% of goat’s diet. Most browse species in the Mediterranean are rich in tanniferous phenolic substances...

Infiltration rate and sediment production were assessed in oak, bunchgrass and sodgrass vegetation types in moderate continuous (MCG), heavy continuous (HCG), and intensive rotation (shortduration, SDG) grazing systems and in a livestock exclosure (LEX). Infiltration rate was related to the total organic cover and bulk density characteristics of the site (RJ = 36). The amount of cover was more ...

Application of existing and novel management techniques can alter traditional livestock grazing patterns and significantly improve the sustainability of arid rangelands. Livestock often congregate and heavily graze riparian areas and other sensitive rangeland, while abundant forage remains in other areas. Increasing the uniformity of grazing can help protect fisheries, wildlife habitat, and oth...
