- Library Collection RecordThe effects of fall and spring grazing by sheep on cover components and recovery following a change in seasonality of grazing practices, were studied within long-term grazing treatments of three-tip…Publication Date 1969

- Library Collection RecordIpomopsis aggregata exhibits substantial powers of regrowth following removal of its primary shoot by herbivores, but Bergelson and Crawley found no evidence of overcompensation in several studies: 1…Publication Date 1969

- Library Collection RecordIn this Indiana greenhouse study, Benner found that total seed weight per Thlaspi arvense plant was higher for early-removal plants than late removal, under all nutrient treatments, but intact…Publication Date 1969

- Library Collection RecordIn this article, Belsky states that if overcompensation in total productivity is ever found in natural communities, it will most probably be found in moderately grazed wetlands such as the ones…Publication Date 1969

- Library Collection RecordBeever et al. modeled the impacts of cattle and burros grazing on soil and vegetation in the Mojave National Preserve among years and environmental gradients. Soil aggregate stability increased as…Publication Date 1969

- Library Collection RecordExpansion of a 6-year old prairie dog colony to a previously uncolonized site resulted in loss of perennial grasses and their replacement by annual forbs within 3 years. Kentucky bluegrass (Poa…Publication Date 1969

- Library Collection RecordThis study, in Illinois, found that Trillium stem height was positively correlated with the percent of the herbaceous understory that is browsed, which indicates that change in stem height can be a…Publication Date 1969

- Library Collection RecordPlants that overcompensate for herbivory are relatively healthier when damaged. In this mutualistic association, the herbivore benefits from the plant, and the plant benefits from the herbivore…Publication Date 1969
