Gunnison prairie dogs have been shown to produce alarm calls that incorporate information about predators [Slobodchikoff et al., Anim. Behav. 42, 713–719 (1991)], such as the species of predator and also a description of the color and general size of the predator. The alarm calls contain a series of

Quantifying physiological stress in wild animals is essential for understanding their health, reproductive success, and survival in a variable environment. The yellow-bellied marmot (Marmota flaviventer) study at the Rocky Mountain Biological Laboratory near Crested Butte, Colorado, USA is the world

With global climates changing rapidly, animals must adapt to new environmental conditions with altered weather and phenology. The key to adapting to these new conditions is adjusting the timing of reproduction to maximize fitness. Using a long-term dataset on a wild population of yellow-bellied marm

A winter orographic cloud seeding program has been conducted in the Gunnison, Colorado region for the past eight winter seasons. The intended target area is elevations above 9,000 feet MSL that provide streamflow to Blue Mesa Resevoir located in western Gunnison County. The goal of this operational

Abstract This research hypothesizes that changes in command and control along with increased levels of trust and training led to a stronger response in Colorado’s 2013 Black Forest fire than that of the 2012 Waldo Canyon fire. Because the fires were categorized as the worst in the region’s history,

Conservationists have long contended, largely in impressionistic terms, that 70 years of American dam building and water diversion have destroyed the biological richness of the Colorado River delta, a key nursery of marine life at the end of the Southwest's great watercourse. Now researchers have co

Years of drought and climate change are causing water resources to dwindle in the Colorado River Basin. But farmers and scientists are collaborating to learn how to grow crops with less water.

AbstractThe persistence of threatened wildlife species depends on successful conservation and restoration of habitats, but climate change and other stressors make these tasks increasingly challenging. Applying climate change vulnerability analyses to contemporary wildlife management can be difficult

The Gunnison tillite was first described in a paper presented by the present authors at the 1924 December meeting of the Geological Society of America. Further geologic and physiographic field studies have established a somewhat widespread distribution of this formation and appear to justify a close

The nests, with one exception, have been placed on horizontal limbs of a distance of from five to fifteen feet out from the trunk of the tree, and from seven to thirty feet high. On July 15, 1907, a nest containing young just hatched was found placed about seven feet up, and in, next to the body of

ABSTRACT: Tertiary rocks more than 5,000 feet thick outcrop in central South Park, Colorado; they include continental sediments and volcanics. These rocks have been previously divided into several formations, from youngest to oldest: Denver Formation (Eocene), and lower andesite of the Thirtynine Mi

A survey of granitic rock surfaces, talus and outcrops, at 25 sites in Rocky Mountain National Park yielded 81 saxicolous lichen species. Fifteen species in 11 genera, or 19% of the total species, were dominant. Observed only once were 31% or 25 species. No new species were reported. Our results sho
