The Effects of Grazing on Ecosystem Productivity

Article: Quantitative effects of grazing on vegetation and soils over a global range of environment Authors: Milchunas, D.G. and Lauenroth, W.K. Published: Ecological Monographs, 63(4). 1993. pp. 327-366 We have given significant consideration to Samuel McNaughton’s grazing optimization hypothesis.  Essentially, … Continue reading

The Natural Cycles of Grazing Ungulates

Article: Ecology of a Grazing Ecosystem: The Serengeti Authors: McNaughton, S.J. Journal: Ecological Monographs, 55(3) 1985, pp. 259-294 In previous posts, we have analyzed research dealing with spatial heterogeneity on the landscape.  Sometimes spatial heterogeneity is a desirable management objective, … Continue reading

Utilization and Multi-Species Grazing in the African Serengeti

Article: Ecology of a Grazing Ecosystem: The Serengeti Authors: McNaughton, S.J. Journal: Ecological Monographs, 55(3) 1985, pp. 259-294 McNaughton’s research also sheds light on the proportions of utilization and the effects of multiple ungulate species harvesting biomass from the same … Continue reading

Plant Productivity and Compensatory Growth

Article: Ecology of a Grazing Ecosystem: The Serengeti Authors: McNaughton, S.J. Journal: Ecological Monographs, 55(3) 1985, pp. 259-294 As noted, the relationships between grazers, grasses, and other biota are complex and highly connected.  The research of Samuel J. McNaughton has … Continue reading

Grazing ungulates, plant biomass concentrations, and nutrient cycling

The evolutionary ecologist S.J. McNaughton is well-known as a strong advocate of the grazing optimization hypothesis.  Essentially, this hypothesis is summarized as follows: …grazing benefits many grasses and other plants in grassland ecosystems… moderate grazing promotes the productivity of many … Continue reading

The Grazing Optimization Hypothesis

Article: Compensatory plant growth as a response to hervibory Author: McNaughton, S.J. Journal: Oikos 40: 329-336 1983 The relationship between grasses and grazers is a complex one influenced by a number of biotic and abiotic factors.  Some researchers and theorists … Continue reading
