Despite our growing knowledge on plants' functional responses to grazing, there is no consensus if an optimum level of functional aggregation exists for detecting grazing effects in drylands. With a comparative approach we searched for plant functional types (PFTs) with a consistent response to grazing across two areas differing in climatic aridity, situated in South Africa's grassland and sava...
Circulating microRNAs (c-miRNAs) are associated with physiological adaptation to acute and chronic aerobic exercise in humans. To investigate the potential effect of grazing movement on miRNA circulation in cattle, here we profiled miRNA expression in centrifugally prepared exosomes from the plasma of both grazing and housed Japanese Shorthorn cattle. Microarray analysis of the c-miRNAs resulte...
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...
The source of blood meals from 174 fed Glossina morsitans submorsitans Newstead, captured in malaise traps in Savanna woodland in The Gambia, were identified by the precipitin test. Warthog accounted for 90% of the meals and single bushbuck and ox feeds were identified. Nagana is a major problem in the area, but contact between tsetse and livestock is reduced by restricted grazing. In this situ...
Responses of plants to grazing are better understood, and more predictable, than those of consumers in North American grasslands. In 2003, we began a large-scale, replicated experiment that examined the effects of grazing on three important arthropod groups-beetles, spiders, and grasshoppers-in shortgrass steppe of north-central Colorado. We investigated whether modifications of the intensity a...

One of the key factors in managing a rangeland is to determine the relative preference of its major plant species by thegrazing livestock. Preference value of each plant species is affected by plant type, companion plants, availability byanimals, phenological stage, climate condition, and the livestock species. We investigated the grazing behaviour of anative goat (Garizi) in the steppe rangela...
Kansas State University Agricultural Experiment Station and Cooperative Extension Service Previously, the release of Conservation Reserve Program (CRP) acres for emergency haying and grazing was a result of drought conditions. Under new program rules, haying and grazing is now allowed on eligible acres regardless of moisture conditions under managed haying and grazing. Managed haying and grazin...
