The effects of harvest on the annual and seasonal survival of willow ptarmigan Lagopus
lagopus L. were tested in a large‐scale harvest experiment. Management units were …

Mountain goats have been among the least studied of North American ungulates, leaving
wildlife managers with little information on which to base harvest strategies or conservation …

Climate change is occurring at an accelerated rate in high-elevation alpine and mountain
ecosystems. Cold-adapted, mountain species are at risk due to forecasted change and …

There is increasing evidence of indirect effects of hunting on populations. In species with
sexually selected infanticide (SSI), hunting may decrease juvenile survival by increasing …

Climate change represents a primary threat to species persistence and biodiversity at a
global scale. Cold adapted alpine species are especially sensitive to climate change and …

Snow is a major, climate-sensitive feature of the Earth's surface and catalyst of
fundamentally important ecosystem processes. Understanding how snow influences …

Species that inhabit naturally fragmented environments are expected to be spatially
structured and exhibit reduced genetic diversity at the periphery of their range. Patterns of …

Unbiased estimates of mountain goat (Oreamnos americanus) populations are key to
meeting diverse harvest management and conservation objectives. We developed logistic …

Helicopter flights may affect wildlife, but habituation to disturbance is possible. We tested the
hypothesis that mountain goats in a population exposed to helicopter flights for over 40 …

Ecological theory predicts that individual survival should vary between sex and age
categories due to differences in allocation of nutritional resources for growth and …
