We estimated wild pig (Sus scrofa) densities in the southeastern United States using both removal and spatial mark-resight models. We compared the reported densities and corresponding coefficients of variation between model types and investigated the factors that influenced dissimilarity between different model type estimates.

We found variable spatial and temporal patterns and predictability of plant phenological progression across 8 pronghorn ranges in Montana. We sampled potential exposure to phenology values for migrants and residents along spring movement paths and summer ranges and found that within herds and years the resident and migrant movement strategies conferred similar exposure to indices of nutrition.
