Behavioral and demographic responses of mule deer to energy development on winter range
Anthropogenic habitat modification is a major driver of global biodiversity loss. In North America, one of the primary sources of habitat modification over the last 2 decades has been exploration for and production of oil and natural gas (hydrocarbon…
Variation in ungulate body fat Individual versus temporal effects
The use of ultrasonograhic measurements of muscle and body fat represent a relatively new data stream that can be used to address questions regarding ungulate condition. We have learned that measurements of body fat and presumably overall body…
Mortality of mule deer fawns in a natural gas development area
Recent natural gas development has caused concern among wildlife managers, researchers, and stakeholders over the potential effects on wildlife and their habitats. Specifically, understanding how this development and other factors influence mule deer…
Reproductive success of mule deer in a natural gas
development area
Natural gas development is increasing across North America and causing concern over the potential impacts on wildlife populations and their habitat, particularly for ungulate species. Understanding how this development impacts reproductive success…
Quantifying spatial habitat loss from hydrocarbon development through assessing habitat selection patterns of mule deer
Extraction of oil and natural gas (hydrocarbons) from shale is increasing rapidly in North America, with documented impacts to native species and ecosystems. With shale oil and gas resources on nearly every continent, this development is set to…
Asynchronous vegetation phenology enhances winter body condition of a large mobile herbivore
Understanding how spatial and temporal heterogeneity influence ecological processes forms a central challenge in ecology. Individual responses to heterogeneity shape population dynamics, therefore understanding these responses is central to…
Relating the movement of a rapidly migrating ungulate to spatiotemporal patterns of forage quality
Migratory ungulates exhibit recurring movements, often along traditional routes between seasonal ranges each spring and autumn, which allow them to track resources as they become available on the landscape. We examined the relationship between spring…
Landscape and anthropogenic features influence the use of auditory vigilance by mule deer
While visual forms of vigilance behavior and their relationship with predation risk have been broadly examined, animals also employ other vigilance modalities such as auditory vigilance by listening for the acoustic cues of predators. Similar to the…
Fine-scale genetic correlates to condition and migration in a wild cervid
The relationship between genetic variation and phenotypic traits is fundamental to the study and management of natural populations. Such relationships often are investigated by assessing correlations between phenotypic traits and heterozygosity or…
Effects of male-biased harvest on mule deer: Implications for rates of pregnancy, synchrony, and timing of parturition
Evaluating how management practices influence the population dynamics of ungulates may enhance future management of these species. For example, in mule deer (Odocoileus hemionus), changes in male/female ratio due to male-biased harvest may alter…
