Many animals, including gray wolves (Canis lupus), live in social groups. Genetic techniques can help reveal the structure and composition of social groups, providing valuable information about group and population dynamics. We evaluated the effectiv

Various monitoring methods have been developed for large carnivores, but not all are practical or sufficiently accurate for long-term monitoring over large spatial scales. From 2009 to 2010, we used a predictive habitat model to locate gray wolf rend

Genetic data are increasingly used to describe the structure of wildlife populations and to infer landscape infl uences on functional connectivity. To accomplish this, genetic structure can be described with a multitude of methods that vary in their

Summary 1. Well-informed management of harvested species requires understanding how changing ecological conditions affect demography and population dynamics, information that is lacking for many species. We have limited understanding of the relative

We studied gray wolf (Canis lupus) homesite attendance rates using global positioning system locations of 17 GPS-radiocollared wolves from 7 packs in Idaho. Nonbreeding wolves attended homesites more once pups were weaned and we hypothesize this is a

Populations of mule deer Odocoileus hemionus have declined throughout most of their historic range in recent decades, and habitat alteration has been hypothesized as one potential cause of those declines. Consequently, understanding how patterns of b

Manipulating predator populations is often posed as a solution to depressed ungulate populations. However, predator—prey dynamics are complex and the effect on prey populations is often an interaction of predator life history, climate, prey density

Understanding survival and cause-specific mortality of native and translocated animals can help biologists design more effective recovery programs. We estimated survival rates for 181 native mountain quail (Oreortyx pictus) in west-central Idaho from

Summary 1. Understanding the interaction among predators and between predation and climate is critical to understanding the mechanisms for compensatory mortality. We used data from 1999 radio-marked neonatal elk (Cervus elaphus) calves from 12 popula

Roads and associated human development are prevalent features in many landscapes and can have significant impacts on wildlife populations, including the creation of barriers to movement that can reduce connectivity within and among populations. We ev
