Studies on the ecology of avian malaria in an alpine ecosystem
Much of global biodiversity is comprised of parasitic organisisms. It is well recognized that the selective pressures imposed by parasites shape host defenses and life-history strategies. Many studies suggest that human changes to the environment facilitate pathogen emergence by disrupting establish
New stratigraphic interpretations, geochemistry, and petrophysics of the lower Mancos group, Douglas Creek Arch, northwestern Colorado, U.S.A.
A study of regional stratigraphy, geochemistry, and petrophysics of the interval between the Lower Mancos Shale and the Dakota Formations on the Douglas Creek Arch was conducted to investigate its resource potential as an unconventional gas accumulation.The purpose of this study was to test the hypo
An analysis of whirling disease risk in Western Montana
Myxobolus cerebralis, the causative agent of whirling disease, has been a major contributor to the loss of young trout in numerous streams within the Intermountain West (Colorado, Idaho, Montana, Utah, Wyoming). Currently there are no effective management procedures for mitigating the effects of thi

Butterfly foraging behavior: can butterflies detect nectar in flowering plants?
Optimal foraging theory states that there are benefits and costs from foraging. If the animal shows optimal foraging behavior, the benefits minus the costs from foraging should be maximized. One assumption of optimal foraging theory is that animals can recognize food, which for butterflies means det
What determines the distribution of red-naped sapsuckers in the East River Valley?
The conservation of keystone species and their associates is of great importance due to the disproportionately large role they play in community and ecosystem structure. The Red-naped Sapsucker (Sphyrapicus nuchalis) is considered part of an intricate keystone species complex in the aspen forests of
Temporal variation in high elevation plant-pollinator communities
Plant-pollinator communities contribute to global diversity and are a good indicator of the health of an ecosystem. Climate change is causing phenological changes of flowering plants and pollinators. Changes in plant phenology can lead to a pollinator not being able to find sufficient pollen and nec
Patterns and mechanisms of invasion of conifer (<i>Abies lasiocarpa</i> and <i>Picea engelmanni</i>) into aspen forest and montane meadow
Climate Change is Causing A Decline in Bombus occidentalis by Reducing its Floral Resources
Concerns of the decline of pollinators and their services have recently been raised. While several hypothesis have been studied, such has the shift of flowering phenology so it no longer overlaps with pollinators and habitat fragmentation, this study investigated the decline of the nectar robbing bu
Structural and stratigraphic controls on fracture distribution within sand bodies of the Upper Iles and Lower Williams Fork formations, Mamm Creek and Divide Creek fields, Piceance Basin, Colorado
The Mesaverde Group in the Piceance Basin of northwestern Colorado is a continuous tight gas accumulation that has established itself as one of the more prolific producers of natural gas in the Rocky Mountain Region.In the Piceance Basin, the most significant producing intervals within the Mesaverde

Linking drift and benthic density along fishless to fish transitions in Rocky Mountain streams
The influence of predators on drift and benthic density is important for understanding prey community structure in freshwater streams. Drift activity of stream invertebrates in fishless streams does not differ between day and night, but when visual drift-feeding trout are present, stream invertebrat
