Experimental Analyses of Population Dynamics: Scaling Up to the Landscape, provide classic examples of extreme variation in densities for vertebrates (Stenseth and Ims 1993). Multiple factors clearly influence patterns of variation in density, although there is little agreement on which factors are most important under what circumstances. Advances in comparative and expe

EMS Studies at the Individual, Patch, and Landscape Scale: Designing Landscapes to Measure Scale-Spes exhibit substantial demographic and spatial structure that is, in some way, related to this variability. Inequalities in the capacity of local habitat patches to produce or absorb dispersing individuals creates a regional population dynamic with a hierarchical demographic component—birth and death

Demographic Parameter Estimation for Experimental Landscape Studies on Small Mammal Populationsy interested in variation in animal numbers over time and space and in the degree to which such variation is caused or influenced by characteristics of the landscape. Animal abundance is determined by rates of survival, reproduction, and movement. Variation in abundance over time and space is a func
