Environmental dynamics and anthropogenic development alter philopatry and space-use in a North American cervid

Using a movement-derived home range estimator, we documented incredibly high spatial fidelity to seasonal ranges in mule deer. Natural gas development reduced this fidelity in some case.

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 …

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 …

Illegal killing for ivory drives global decline in African elephants

Illegal wildlife trade has reached alarming levels globally, extirpating populations of commercially valuable species. As a driver of biodiversity loss, quantifying illegal harvest is essential for conservation and sociopolitical affairs but …

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 helicopter capture and handling on movement behavior of mule deer

Research on wildlife movement, physiology, and reproductive biology often requires capture and handling of animals. Such invasive treatment can alter behavior, which may bias results or invalidate assumptions regarding representative behaviors. To …

Linking genotype, ecotype, and phenotype in an intensively managed large carnivore

Numerous factors influence fitness of free‐ranging animals, yet often these are uncharacterized. We integrated GPS habitat use data and genetic profiling to determine their influence on fitness proxies (mass, length, and body condition) in a …

Effects of Humans on Behaviour of Wildlife Exceed Those of Natural Predators in a Landscape of Fear

Background Human disturbance can influence wildlife behaviour, which can have implications for wildlife populations. For example, wildlife may be more vigilant near human disturbance, resulting in decreased forage intake and reduced reproductive …

Mad cow policy and management of grizzly bear incidents

Protection of humans and livestock from disease has been used to justify many aggressive and costly wildlife control programs. Recent regulatory changes on livestock carcass disposal aimed at controlling the spread of bovine spongiform encephalopathy …
