Scale of plasticity and local adaptation in <i>Boechera stricta </i> along an altitudinal gradient
As environments change, natural selection will increasingly favor plasticity, a mechanism by which organisms express variable phenotypes based on their abiotic or biotic environment. While these trends occur in sweeping macroenvironmental or coarse-grain patterns, this variation can also exist on an
Cryptic behavior in moths
Plant and animal succession in an old burn
Pollinator mediated selection in an <i>Ipomopsis</i> hybrid zone in Poverty Gulch, Gunnison County, Colorado
The effect of habitat on intra-generic competition
Competition and habitat selection have been great topics for ecologists for decades and play a vital role in the study of ecology. In order to avoid competition, organisms partition their niches. Burying beetles (genus: Nicrophorus) occupy the small carrion niche and use carcasses as their primary r
A comparison of the plant and animal life in a coniferous climax forest and an aspen sub-climax forest employing various methods of study; general animal study included
Conservation of pollinators and petal shed in blue flax (<i>Linum lewisii</i>)
Nectar dwelling yeasts and their effects on pollinator preference
Pollinators are extremely important in the global ecosystem. Flowers have evolved attractive traits in order to draw these pollinators. Traits like colorful petals draw in pollinators to metabolic rewards such as nectar and pollen, and in return, pollinators transfer pollen between plants. Plants wi
Trait variations of <i>Boechera stricta</i> along an elevation gradient
Plants have been migrating into higher elevations in order to cope with the stresses of the changing climate. However, not all plants are capable of migrating as far or as fast as others. This study examines leaf traits of Boechera stricta, a plant with limited migratory capabilities, at different e
An investigation into the gregarious habits and parasitism of the tortise shell butterfly larvae, <i>Aglais milberti</i>

Behavioral response of Mountain White-Crowned Sparrows towards an interspecific competitor
This study examined interspecific competition between mountain white-crowned sparrows (Zonotrichia leucophrys oriantha) and Lincoln’s sparrows (Melospiza lincolnii) through a playback experiment. Interspecific competitive interactions influence avian fitness by affecting the distribution of species
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
Aspen-grassland ecotone near Gothic, Colorado. I. The study of succession using permanent quadrats. II. Environmental factors in aspen sprout survival
Comparison of vegetation on granodiorite and limestone outcrops on similarly facing slopes near south bank of Judd's Falls
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
