Synergistic effects of climate and land‐use change influence broad‐scale avian population declines

Bird species in the Pacific Northwest of the United States declined most in areas that had both habitat loss and climate change (measured as temperature and precipitation).

Impacts of the Northwest Forest Plan on forest composition and bird populations

We provide a test of the efficacy of the Northwest Forest Plan, showing that despite limiting cutting of old growth forest, wildlfire has caused continued losses and declines in old growth associated birds have been amplified.

Mortality of mule deer fawns in a natural gas development area

Moderate densities of natural gas development in the production phase had limited effect on mule deer fawn survival.

Movement reveals scale dependence in habitat selection of a large ungulate

Using a novel method to assess habtiat selection across spatiotemporal scales defined by animals movements, we show that mule deer display scale-dependent responses to most habitat features but scale-invariant avoidance of natural gas development.

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 …

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 …

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 …

Characterising the impacts of emerging energy development on wildlife, with an eye towards mitigation

Global demand for energy is projected to increase by 40% in the next 20 years, and largely will be met with alternative and unconventional sources. Development of these resources causes novel disturbances that strongly impact terrestrial ecosystems …

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 …
