Yellowstone's grizzlies (Ursus arctos) have been studied for more than 40 years. Radiotelemetry has been used to obtain estimates of the rate of increase of the population, with results reported by Schwartz et al. (2006). Counts of females with cubs-

A useful theory for analyzing ungulate population dynamics is available in the form of equations based on the work of A. J. Lotka. Because the Leslie matrix model yields identical results and is widely known, it is convenient to label the resulting e

This paper attempts to project the trends of Steller sea lion (Eumetopias jubatus) populations in six subdivisions of the western Alaska population. The overall Western Alaska population has declined dramatically since the 1970s. Trends in half of th

A sequence of changes in vital rates observed as populations approach maximal levels has been used as the basis for a “paradigm” for population analysis. Previous work indicates that early survival decreases first, followed by lower reproductive

Difference equation models of wolf and ungulate prey populations were used to estimate the presumed equilibrium ratio by regression of the finite rate of increase of wolf (Canis lupus) populations against wolves per 1000 deer-equivalents of biomass i

Parameters for generalized Lotka-Volterra equations, expressed as difference equations, have been estimated from actual data on wolves and their prey. The functional response is represented by a single constant, while the numerical response is expres
