Introduction to Special Feature on Catastrophic Thresholds, Perspectives, Definitions, and Applications Ecology and Society
Washington-Allen, Robert A; Department of Ecosystem Science and Management, Texas A&M University; washington-allen@tamu.edu; Briske, David D.; Department of Ecosystem Science and Management, Texas A&M University; dbriske@tamu.edu; Shugart, Herman H.; W.W. Corcoran Professor of Environmental Sciences & Director, Center for Regional Environmental Studies, Department of Environmental Sciences, University of Virginia; hhs@virginia.edu; Salo, Lucinda F.; Sage Ecosystem Science; csalo11@hotmail.com.
The contributions to this special feature focus on several conceptual and operational applications for understanding non-linear behavior of complex systems with various ecological criteria at unique levels of organization. The organizing theme of the feature emphasizes alternative stable states or regimes and intervening thresholds that possess great relevance to ecology and natural resource management. The authors within this special feature address the conceptual models of catastrophe theory, self-organization, cross-scale interactions and time-scale calculus; develop operational definitions and procedures for understanding the occurrence of dynamic regimes or multiple stable states and thresholds; suggest diagnostics tools for detection of states and...

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...
