Title: Disturbance by fire frequency and bison grazing modulate grasshopper assemblages in tallgrass prairie: Journal: Ecology; Authors: A. Joern; Date: 2005; Summary: The combined effects of burn frequency (1, 2, 4, 20 and unburned), bison grazing activity (grazed and ungrazed) and topography (upland and lowland) on the local diversity of grasshoppers were examined in Kansas (39Â° 05â€™ N, 96Â° 35â€™ W). Grasshopper species richness and relative abundance was determined from sweep net sampling in early August. Canopy height, plant species richness and biomass of grasses and forbs were measured the same time. ...; Agrovoc Control Words: Grasshoppers, Grazing, Burning; View more details about this article

Title: Grasshopper densities on grazed and ungrazed rangeland under drought conditions in southern Idaho: Journal: Great Basin Naturalist; Authors: D. J. Fielding, and M. A. Brusven; Date: 1995; Summary: Differences in grasshopper densities on light to moderately grazed and ungrazed rangelands under drought conditions were studied in south-central Idaho (between 42â° 37.5â€™ and 43â° 00â€™ N; 114â° 30â€™ and 114â° 00â€™ W). Paired sites, between areas without grazing for 10 years and grazed under a rest-rotation system were used. Grasshoppers were sampled three times over the summer. Estimations of percent ground cover and plant species composition, cover of cryptogams, cattle dung and bare ground were a ...; Agrovoc Control Words: Caelifera, Rangelands, Grazing; View more details about this article

Title: Influence of grazing history on the community structure of grasshoppers of a mixed-grass prairie: Journal: Environmental Entomology; Authors: M. A. Quinn, and D. D. Walgenbach; Date: 1990; Summary: The effect of grazing history by a variety of grazers (bison, cattle, pronghorn, bighorn and domestic sheep, mule and white-tailed deer and black-tailed prairie dogs) on grasshopper communities was studied in southwestern South Dakota. Presence/absence and estimated abundance of grasshoppersâ€™ species were collected in August on grazed and ungrazed sites. Percent canopy coverage for all grass species, total forbs and bare ground were collected in August along with the number of grass species present at each site. ...; Agrovoc Control Words: Grazing, Grasshoppers, Wildlife; View more details about this article

Title: Response of grasshoppers (Orthoptera: Acrididae) to livestock grazing in southeastern Arizona: Differences between seasons and subfamilies: Journal: Oecologia; Authors: K. Jepson-Innes, and C. E. Bock; Date: 1989; Summary: The effect of cattle grazing on grasshopper densities was studied in Santa Cruz County, Arizona for two years. Two grazing treatments (grazed, ungrazed) were examined. Grasshopper densities were measured weekly from July to August (summer) of the first year and July to August (summer) and September to October (fall) of the second year. Percent bare ground and canopy cover of each plant species were recorded in August of the second year. ...; Agrovoc Control Words: Grazing, Rangelands, Grasshoppers; View more details about this article
