Effects of water availability on expression of vegetative traits in Ipomopsis across space and time
In subalpine ecosystems, climate change has contributed to an earlier snowmelt as a result of warmer temperatures in the winter and spring. This shift may act to limit water availability for plant communities by prolonging the period between initial snowmelt and late-season monsoon rains, placing th

Can <i>Speyeria mormonia</i> detect nectar in a floret? A study in butterfly foraging behavior
Macroinvertebrate excretion rates and their contribution to nutrient cycling in a rocky mountain stream
Nutrient supply into an ecosystem is an important factor that can influence its productivity. While some nutrients enter the ecosystem from external sources, cycling of nutrients internally can also be an important process in determining nutrient supply. In this study I examined the role of benthic
Examining the impact of pollen diet composition on bee development and lifespan
Pollen is the sole protein source for most bees and the largest component of their larval diets.

Control of Potato Insects with Foliar Insecticides, Larimer County, Colorado, 1985
Abstract ‘Russet Burbank’ potatoes were planted 9 May, ’85 at the Colorado State University Horticulture Research Center, Larimer County, CO. Plots were 3 row (30 inch spacing), 25 ft in length randomized in a complete block design with 4 replications. Treatments were applied 12 Aug using a CO2 comp

Biofluorescence as a Mechanism of Sexual Selection in Ambystoma mavortium nebulosum
Biofluorescence, the re-emission of absorbed light at lower energy wavelengths, has been widely documented in marine organisms and recently observed in amphibians. This phenomenon, particularly in amphibians such as frogs, salamanders, and newts, suggests potential roles in ecological interactions,

Holarctic marmots as a factor of biodiversity
Emergence mass is highly correlated with immergence mass, but explains about 55% of the variation. There is a 2- fold difference in body mass among marmot species. Total mass loss during hibernation is correlated with immergence mass. All measures of mass loss are correlated with each other. Big spe

Conditional Exploitation and Context-Dependent Fitness Consequences of Pollination Mutualisms
The aboveground primary productivity within each of four areas, differing in length of the snow-free season, was determined in a high subalpine (3380 m) herbaceous meadow in Colorado. Net productivity, minus losses to herbivores, ranged from 114 g -m™ - yr“ in the area with the shortest snow-free pe
