The effect of ants on membracid nymph size and instar
This project aimed to determine the mechanism of which treehopper nymphs grow in the presence of ants. Nymphs (Publilia modesta) are larger when their mutualist partner (Formica obscuripes) is present. There are two ways in which the nymphs can grow: (1) nymphs grow at the same rate, but are larger
Antipredatory response of mule deer (<i>Odocoileus hemionus</i>) to predator urines
Auditory, visual, and olfactory cues of predator presence create a landscape of fear for prey animals. Prey can respond to predation risk perceived from these cues by increasing vigilance, increasing group size, altering habitat use, and reducing activity times. State of the animal and predator type

Recommendations concerning the water system of Gothic, Colorado, and the proposed sprinkler system
Effect of Soil Metals on Pollination of Subalpine Wildflowers
Metals-rich soils can occur naturally or through human activity, such as mining. Plants growing in metal-rich soils often incorporate metals into their tissues; the concentration of these metals varies, and plants which concentrate the metals most strongly are termed hyperaccumulators. Accumulation

Temperature and Nestling Development: Temporal Variations in <i>Zonotrichia leucophrys oriantha</i> Feeding Frequency
Mountain White-crowned Sparrows (Zonotrichia leucophrys oriantha) are unique in that their nestlings, which require parental care for 9 days before fledging, have a 25% higher metabolic rate than other open-nesting passerines. This unusually high energetic demand requires that parents frequently fee
Effects of floral diversity and density on fly (<i>Diptera:Bombyliidae and Syrphidae</i>) floral foraging fidelity in subalpine meadows
Foraging behavior of pollinators is an extensively researched topic. Research on bee, butterfly, and hummingbird foraging behavior has led to a greater understanding of the impacts of plant community composition on foraging behavior. This research has been further enhanced by fly foraging behavior a
