A reappraisal of the evidence for regulation of wolf populations
Abstract The dogma that gray wolf ( Canis lupus ) population densities in naturally occurring systems are limited almost solely by available ungulate biomass is based upon studies that fit straight line linear regressions (Type 1 numerical response) to data collected at 32 sites across North America...
