- Library Collection RecordAldridge and Brigham looked at the change in sage grouse population numbers in central Canada over the past 50-60 years. They mentioned a number of limiting factors that are having an affect on…Publication Date 1969

- Library Collection RecordAllen and Bartolome studied the impact of grazing by cattle and deer for reduction of shrubs and herbaceous plants on tree plantations established on clearcuts in the Sierra Nevada of California.…Publication Date 1969
- grazing

- Library Collection RecordAuthors compared short duration grazing by sheep, in early and late spring, at different stocking intensities. Average daily forage disappearance was higher in the 10-day treatment than the 2-day one…Publication Date 1969

- Library Collection RecordStress from grazing can influence the development of plants and this study uses statistical developmental instability analyses to relate growth characteristics of plants to stress levels caused by…Publication Date 1969
- allometric relationships
- Chrysothamnus greenii
- developmental instability
- grazing impact
- Oryzopsis hymenoides
- Seriphidium novum
- 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
- herbivory
- mutualism
- overcompensation
- plant defense
- Library Collection RecordAuthors measured vegetation and rodent and bird populations in prairie dog towns, where prairie dogs maintain patches of lower vegetation height and percent mulch cover. Plant canopy cover was…Publication Date 1969
- abundance
- black-tailed prairie dog
- Cynomys ludovicianus
- ecosystem regulator
- habitat
- species richness
- Library Collection RecordDepending on the scale of observation and on the factors that determine animal distribution, grazing patterns may be stronger or weaker than vegetation patterns, or may mirror the spatial structure…Publication Date 1969
- herbivory
- competition
- disturbance
- spatial dependence
- spatial heterogeneity
- Library Collection RecordAbdel-Magid et al. used an artificial hoof to simulate 4 levels of trampling intensity typical of continuous and short duration grazing systems, on shortgrass prairie sods, maintained at varying…Publication Date 1969
- infiltration
- soil water
- trampling
- compaction
- herbage loss
- treading
- Library Collection RecordBulk density and water infiltration showed little change in a comparison of 3 grazing systems stocked at light, moderate and heavy levels in a study in Wyoming. While soil bulk density was greater…Publication Date 1969

- sandy loam soil
- short grass rangelands
- short-duration grazing
- Library Collection RecordAbaye et al. compared forage quality and quantity between pastures grazed by sheep and cattle alone and together (multi-species grazing). More forage was available and forage use tended to be more…Publication Date 1969

- Library Collection RecordOver the past dozen years, the population of bison (Bison bison) on the northern winter range of Yellowstone National Park has expanded from the traditional core along the lower Lamar River, occupied…Publication Date 1969

- Library Collection RecordCurrent disturbance models (predation hypothesis, intermediate-disturbance hypothesis, and the Huston hypothesis) do not adequately account for the wide range of responses by grassland plants…Publication Date 1969

- Library Collection RecordOwens et. al. report that the critical time for pastures, in the eastern United States, is during the dormant season, which falls from November through April, typically. This is when conditions are…Publication Date 1969

- Winter Feeding
- Library Collection RecordUtilization of upland and riparian vegetation was measured from 1976-1982 on sites in Idaho, Utah, and Nevada under rotation, rest-rotation, deferred, and season-long continuous grazing strategies,…Publication Date 1969

- Library Collection RecordWithin the ungrazed livestock exclosure, grass cover, herb cover and average height were higher compared to outside the exclosure. Outside the exclosure, fallen tree trunks and exposed soil were…Publication Date 1969
