Test for predator escape mechanisms in ostracods
A study of the behavior of <i>Eutamias</i> near Gothic, Colorado
Does Bumble Bee Diet Breadth vary with the Floral Abundance in a Meadow?
Years of early snowmelt tend to have a decrease in floral abundance throughout the year. This causes flowers to be more susceptible to frost and drought stress. Based on which flowers are successful this can affect bumble bee diet breadth due to the direct correlation between bumble bee proboscis le
Environmental Correlates and Fitness Consequences of a Flower Color Polymorphism in Boechera stricta.
Effects of Insect Damage to <i>Helianthella quinquenervis</i> (Asteraceae) Inflorescences on Pollinator Visitation
Plant reproductive success is often influenced by not only direct effects of flower-eating herbivores (florivores) consuming floral tissues, but also the indirect effects of pollinator visitation. Previous literature suggests that florivore damage can negatively influence pollinator visitation, cons
The Sequence Stratigraphy of the Chinle Formation in the Dinosaur National Monument Region, Utah and Colorado, USA
A Thesis submitted to the faculty of the Graduate School of the University of Minnesota by Ryan Eric Erickson in partial fulfillment of the requirements for the degree of Master of Science, October 2007.
The meadow midst the aspens (<i>Populus tremuloides</i> Michaux.)
Pollinator-mediate selection in Ipomopsis aggregata: does correlational selection explain floral phenotypes?
The theory of pollination syndromes is pervasive in pollination biology. Correlational selection may explain why certain flower phenotypes are selected for by certain pollinators thereby offering support for the theory of pollinations syndromes. Using potted individuals of the hummingbird-pollinated
Ecological restoration of Alder Creek, Colorado, USA
Partial ecological restoration of important attributes of Alder Creek, Gunnison County, CO, U.S.A., has been successful since the area has continued in its restored condition for over a decade. However, due to cattle grazing, the system is not self maintaining and, thus, requires continual managemen
Relaxation of the leaf economics spectrum within and across quaking aspen Populus tremuloides genotypes
Nanda-Hamner Curves Show Huge Latitudinal Variation but No Circadian Components in <i> Drosophila Montana </i> Photoperiodism

Cognitive ecology of pollination
Correlation of leaf and community traits and various spectra in meadows along an elevation gradient
The capabilities of remote sensing technology are advancing rapidly, and with it, the applications of those technologies are also advancing. Indices such as Normalized Difference Vegetation Index (NDVI) have long been used to determine vegetative health, but no direct measurements have been made to
Depositional setting and reservoir-scale architecture of sandstone bodies of the Green River Formation in Evacuation Creek, Dragon Quadrangle, eastern Uinta basin, Utah
The Green River Formation is an Eocene lacustrine deposit that is present in several Rocky Mountain basins.In the Uinta basin, the Green River Formation has produced large amounts of oil and gas from many fields, the largest being the Greater Altamont-Bluebell field in the northern margin of the bas
Reconnaissance geology of the Mississippian Leadville limestone and implications for mineralization controls, Fulford mining district, Eagle County, Colorado
Deserving of much appreciation are Russell K. Murphy, who assisted in navigating the rugged field terrain, and the E. C. Lorig family of Eagle, Colorado, whose friendship, generosity, and guidance were extremely valuable

Host specificity of hemiparasitic Castilleja and its influence on plant community diversity.
Hemiparasitic plants rely on their hosts for some of their nutritional requirements, but are still able to photosynthesize and absorb water and nutrients through their roots. Parasitic plants have been shown to impact plant community diversity by reducing dominant species' competitive ability, thus
