The value of dihydrogen monoxide to a jumping mouse: habitat use and preference in <i>Zapus princeps</i>.
The western jumping mouse, Zapus princeps is common in riparian habitat. There are multiple hypotheses (need for water, food type, or anti-predator/cover) for why this is. The objective of this project was to determine the use of mesic and adjacent drier habitats by Zapus using both a live-trapping

Effects of bacterial endophytes on plant-insect interactions
Insects must interact with bacterial endophytes when sharing a common host. To test the hypothesis that larvae of Scaptomyza nigrita detects and prefers Cardamine cordifolia infected with different strains of Pseudomonas bacteria. Thus, unitizing the JA/SA induced antagonism. When given the choice b

The effects of phenology on <i>Delphinium nuttallianum</i>
The phenology of plants in the alpine environment of the Rocky Mountains is heavily dependent on snowmelt time (Inouye and McGuire 1991, Thomson 2010). In this study we have manipulated the timing of snowmelt in order to change the phenology of Delphinium nuttallianum in the subalpine environment of

Plant size influences mycorrhizal colonization of <i>Polemonium foliosissimum</i>
The purpose of this experiment was to investigate the relationship between the different genders of the gynodioecious species P. foliosissimum and their mycorrhizal associates. Mcyorrhizal colonization of roots was quantified, and soil and plant tissue analyses were performed. Further, a full factor

A comparative study of plant species diversity on three historic mining sites
In order to determine the degree of ecological damage inflicted as a result of mining operations around the Gothic area, three tailings piles were identified in Gothic and Crested Butte and an observational study of plant species on and around them carried out. It was found that both total numbers o
