Title: Interactions among the effects of herbivory, competition, and resource limitation on chaparral herbs: Journal: Ecology; Authors: S. E. Swank, and W. C. Oechel; Date: 1991; Summary: In California, Swank and Oechel assessed the individual and combined effects of four main factors (trenching to reduce root competition, caging to reduce herbivory, nutrient addition, and water addition) on herb germination, survival, and growth in a chaparral dominated by chamise, Adenostoma fasciculatum. Results showed strong interactions among these treatments. Therefore, no single factor can be regarded as causing the absence of herbs in chaparral. Herb establishment was limited by herbivory and root competition with shrubs for limited nutrients and/or water.

Title: Effect of grazing and cultivation on some chemical properties of soils in the mixed prairie: Journal: Journal of Range Management; Authors: J. F. Dormaar, and W. D. Willms; Date: 1990; Summary: Dormaar and Willms studied the components of the organic matter in soil under 3 mixed prairie types: grassland dominated by needle-and-thread/blue grama (Stipa comata/Bouteloua gracilis) in good range condition; grassland significantly modified by grazing, dominated by blue grama and in poor range condition; and grassland, dominated by needle-and-thread/blue grama in good range condition, but converted to cropland and under continuous wheat for 4 years. Soils in grazed pastures had less monosaccharides and more microbial carbohydrates than soils insi ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article
