Influence of livestock grazing on C sequestration in semi-arid mixed-grass and short-grass rangelands.
We evaluated the effects of livestock grazing on C content of the plant-soil system (to 60 cm) of two semi-arid grasslands: a mixed-grass prairie (grazed 12 years), and a short-grass steppe (grazed 56 years). Grazing treatments included season-long grazing at heavy and light stocking rates, and non-grazed exclosures. Significantly higher soil C (0-30cm) was measured in grazed pastures compared ...
متن کاملPlant Species and Functional Types’ Diversity in Relation to Grazing in Arid and Semi-arid Rangelands, Khabr National Park, Iran
In arid and semi-arid rangelands, grazing as one of the natural or human induced processes has direct and indirect effects on structure and dynamics of plant community and ecosystems. A study was done to analyze the effects of grazing on plant species diversity and Plant Functional Types‘ (PFTs) diversity of arid and semi-arid rangelands. We analyzed plant richness and diversity data from 75 sa...
متن کاملVegetation Pattern Formation in Semi-Arid Grazing Systems
Hypotheses about the origin of vegetation pattern formation in semi-arid areas around the world almost all include a common feature of semi-arid areas: the presence of a positive feedback between plant density and water infiltration. We investigate whether this positive feedback and the spatial redistribution of runoff water are sufficient to explain vegetation pattern formation. For this purpo...
متن کاملVariation in absorption and excretion of calcium in grazing sheep in a semi-arid grazing ranch, Punjab, Pakistan
The calcium status of lactating, non-lactating, and male sheep on farm in southwestern Punjab, Pakistan was studied. Pasture and animal were sampled at the end of the first month of summer and winter. All samplings were carried out fortnightly. A mineral supplement was available to all animals throughout the year. Plasma calcium in all animals was not affected by the physiologic state and gende...
متن کاملCorrection: Changes in Semi-Arid Plant Species Associations along a Livestock Grazing Gradient
In semi-arid ecosystems, vegetation is heterogeneously distributed, with plant species often associating in patches. These associations between species are not constant, but depend on the particular response of each species to environmental factors. Here, we investigated how plant species associations change in response to livestock grazing in a semi-arid ecosystem, Cabo de Gata-Níjar Natural P...
