Mutualistic interactions between flowering plants and bees are a pairwise interaction, but exist in a network of similar interactions (Bronstein, 2001). The outcomes of these interactions differ, for example, the costs and benefits for flowering plants caused by floral visitors (Bronstein, 2001). Lu

We use relative dating criteria to document post-depositional alteration of till and periglacial deposits, and to map these deposits as facies of four allostratigraphic units (alloformations) in the Wind River Range. The alloformations are composed of till as well as rock-glacier, protalus-rampart,

In Colorado and the southwestern United States, quaking aspen (Populus tremuloides Michx.) is a species of high ecological, economic, and aesthetic importance. In response to the interests of several landowners and land managers in my study sites, this thesis describes my efforts to identify differe

Vigilance is an anti-predator behavior responsible for ensuring the survival of an individual. This behavior directly benefits the individual, as well as conspecifics by scanning for potential threats. The amount of time devoted to vigilance in yellow-bellied marmots varies based on many factors inc

Mutualistic interactions are ubiquitous in nature. These type of interactions generally provide benefits to interacting species. Insects and plants are commonly involved in diverse forms of mutualism, however little is known if genetic variation among plants allows for a positive symbiosis with arth

Hemiparasites such as those in the genus Castilleja have important effects on the plant communities they are found in. For example, hemiparasitic plants may reduce the abundance of dominant plant species, opening niche space for sub- ordinates. This effect may be driven by direct parasitism of Casti

Boechera stricta, a native forb common to the Rocky Mountain range in western North America, is a model species at the forefront of genetics and ecology. Over millennia, in response to herbivory, plants have developed secondary metabolite defensive compounds to deter wide ranges of herbivores. Gluco
