Effects of species composition change under experimental warming on soil microclimate in a montane meadow
The results of a long-term experimental warming study, in a montane meadow in the Rocky Mountains of Colorado, have shown that Artemisia tridentata (Common Sagebrush) is likely to increase in abundance under climate change, as perennial forb species decrease in abundance. This change in species comp
<i>Scaptomyza nigrita</i> herbivory and inducible glucosinolates in <i>Cardamine cordifolia</i>
Brassicaceae plants, such as bittercress (Cardamine cordifolia) produce characteristic glucosinolates, which are secondary metabolites used as defense compounds to deter pathogens and insect herbivores, such as the leaf mining fly (Scaptomyza nigrita). These compounds are produced constitutively and

Vigilance in the golden-mantled ground squirrel (<i>Spermophilus lateralis</i>): effect of age and distance to human-created structures
Animals are expected to maximize feeding success while minimizing predation risk; however, foraging and vigilance behaviors often conflict. I studied this trade-off in Golden- mantled ground squirrels (Spermophilus lateralis), with respect to human-created structures in Gothic, CO, site of the Rocky

Role of floral nectaries and plant sex in mediating ant-aphid interactions on <i>Valeriana edulis</i>
Multi-species interactions profoundly affect community composition and function of ecosystems. Foraging behavior and resource allocation are two key factors that determine how species interact. This study investigates the role of floral nectaries and plant sex in mediating ant-aphid interactions on
Effect of Nitrogen on Linaria vulgaris and Native Species
We studied the effect of varying amounts of soil nitrogen on Linaria vulgaris and native species. Linaria vulgaris is an invasive weed in the Rocky Mountains that forms monocultures, hindering the growth of native plants. The Rocky Mountain soils are nitrogen-poor, and we expected nitrogen-reduced s

Variation in interaction zone size and influence of sex on fitness components of Valeriana edulis
Sex and size allow for many different types of individuals within one species. These individuals can have different needs, which can influence responses to interaction, as well as what interactions take place between species members. We modeled how the sex and size of individuals of Valeriana edulis

Effects of Bombus Pollinator Removal on Fly Foraging Behavior.
Native Bombus species are in decline in the United States. Since pollinators are such integral species in a system, the extinction of a single Bombus species could potentially have far reaching consequences on crop production and plant reproduction necessary for species diversity ad agriculture. How
