Nest Distribution of <i> Bombus </i> spp. Across Different Habitat Types
Despite bumble bees’ critical importance as pollinators throughout the montane regions of Colorado, little research has been done on their nesting habits. In order to conserve the populations of Bombus spp. in the West, better knowledge of their nest density and nesting habitats is needed. I hypothe

Mule deer (<i>Odocoileus hemionus</i>) respond to yellow-bellied marmot (<i>Marmota flaviventris</i>) alarm calls
Individuals may obtain valuable information about the presence of predators by eavesdropping on heterospecific alarm signals. While playback studies have demonstrated that similarly-sized and taxonomically-related species may respond to the calls of each other, less work has been done to define the

Biologically Significant Areas in Gunnison County Colorado
How do above and belowground grass-fungus symbioses change over elevational gradients in mountainous Colorado?
Plants and fungi are closely associated and likely have been since terrestrial ecosystems were first inhabited. These symbiotic relationships have taken two main forms: internal aboveground symbionts known as endophytes, and belowground root associated fungi, the most common of which are mycorrhizal
Understanding pollen specialization in mason bees: a case study of six species
Many bee species are dietary specialists and restrict their pollen foraging to a subset of the available flowers. However, the reasons for specialization—and the reasons certain plant taxa support numerous specialists—are often unclear. Many bees specialize on the plant family Asteraceae, despite ev
FOSSIL PLANTS AND PALYNOMORPHS FROM THE LATE PALEOZOIC CUTLER FORMATION, EASTERN PARADOX BASIN
The late Paleozoic Cutler Formation, where exposed near the modern-day town of Gateway, Colorado, has traditionally been interpreted as the product of alluvial fan deposition within the easternmost portion of the Paradox Basin. The Paradox Basin formed between the western margin of the Uncompahgre U

The structure and function of subalpine ecosystems in the face of climate change
Subalpine ecosystems are experiencing rapid changes in snow pack, temperature, and precipitation regime as a result of anthropogenic climate forcing. These changes in climate can have a profound effect on subalpine ecosystem structure and functioning, which may ultimately feed back to climate change
