Wintertime Supercooled Liquid Water Flux over the Grand Mesa, Colorado
Supercooled liquid water (SLW) and wind measurements were made over the Grand Mesa of western Colorado during the period late January through March, 1986. Observations were obtained with an instrumented aircraft, a tower-mounted icing rate meter, and an acoustical sounder. These data were used to es
Stoichiometry and infectious disease: Linking chemical elements and parasitic interactions
A growing body of work has shown that parasites’ growth and reproduction can be influenced by the food quality available to their hosts. Consumers, including parasites, require a balanced diet to grow. Unlike many consumers, however, parasites are beholden to the diet quality presented to them by th

Experimental test of the ability of plants to regulate their temperatures under climate change: Using transplanted communities, thermal imaging, and arcGIS across an elevation gradient
The question of thermoregulation in plants is increasingly important in a rapidly changing climate. Plants have long been considered poikilotherms, where internal temperatures are decided by the external environment. However, observations show that plants have some ability to thermoregulate. If plan
Social security: Does social position influence flight initiation distance?
A variety of factors can influence an individual’s antipredator behavior including their group size because simply being around conspecifics may reduce predation risk. Recent work has shown that it is not just being around others, but rather the specific social relationships that individuals have wi

Tight-Sand Development Potential in the Southern Rulison Area, Garfield County, Colorado
Summary Reservoir characterization and simulation of natural gas production were used to assess the production potential for an extension area within the Piceance Creek basin (Garfield County, CO). Many of the basin's reservoirs are lenticular sands characterized as having low porosities, low permea
Functional relationships between early play behavior and adult dominance roles in yellow-bellied marmots (<i>Marmota flaviventris</i>)
Play has been defined as apparently functionless behavior, yet since play is costly, it must have some function (or functions) to outweigh its costs. We provide the strongest evidence for a long-standing, but poorly supported hypothesis: that early play is practice for later dominance relationships.

Variation of Pollen Mass Across Species, Habitat Types, and Time
Bumble bees are crucial pollinators in both agricultural and wild ecosystems, and as pollinators they rely almost exclusively on floral resources as a source of food. However, in many natural and agricultural areas there has been a decrease in floral diversity and abundance, which in turn has caused
