Grasshopper Population Ecology: Catastrophe, Criticality, and Critique Ecology and Society
Lockwood, Dale R; Colorado State University; dale.lockwood@colostate.edu; Lockwood, Jeffrey A; University of Wyoming;.
Grasshopper population dynamics are an important part of the North American rangeland ecosystem and an important factor in the economies that derive from the rangeland. Outbreak dynamics have plagued management strategies in the rangeland, and attempts to find simple, linear and mechanistic solutions to both understanding and predicting the dynamics have proved fruitless. These efforts to ground theory in a correspondence with the “real” world, including whether the population dynamics are ultimately density dependent or density independent, have generated abundant heat but little light. We suggest that a pragmatic approach, in which theories are taken to be “tools” rather than competing claims of truth, has greater...
