A study of interactions within a marmot family
A brief survey of the mushrooms in the spruce-fir forest of the Gothic, Colorado area
Introductory field investigation of the distributional ecology of the Anostraca (Crustacea) of north-central Gunnison County, Colorado
The effect of monocotyledon and dicotyledon plants on soil porosity
The effect of sampling effort on species richness estimates of flower visitors
Estimates of species richness, while useful and common to many subdisciplines of biology, are problematic in their reliance on adequate sampling effort. How much sampling is required for an accurate estimate of species richness, and what levels of sampling will render communities comparable? This st
A study of the life cycles of <i>Formica neorufabarbis</i> and <i>Formica fusca</i>
Effects of trophic phenological synchrony or dyssynchrony on maternal investment of a small herbivorous mammal (Callospermophilus lateralis)
A contrast of the vascular vegetation found in an old sagebrush community and a new one
Effects of the nuisance diatom <i>Didymosphenia geminata</i> on invertebrates in a Rocky Mountain stream
Nuisance blooms of the stalked diatom Didymosphenia geminata have become an increasing concern worldwide, yet little is known about their effect on stream food webs. We investigated the effects of D. geminata blooms on stream invertebrates of the East River in the western Rocky Mountains. Areas with
Solitary bee genera differ in foraging activity timing and temperature; Evidence of a seasonal dietary shift in Hoplitis fulgida
Global warming, and exacerbated warming temperatures with humane activity, could impose novel conditions on the lives of many organisms. Of those, the behaviors and diets of solitary bees face adaptive stress as their optimal foraging conditions and preferred floral resources fluctuate. Trap nests m
Enteric microparasites of amphibians of the Elk Mountains, Colorado
Community-level interaction in avian vocalizations
Social Security: Do Individuals in Tight-Knit Social Groups Perceive Greater Security?
Antipredator behavior is influenced by many factors including group size. Group size effects are seen when animals in larger social groups allocate less time to antipredator vigilance while foraging, but group size alone does not capture the diversity and complexity of sociality and behavior. An ind
The effects of water and phosphorus on floral traits and nectar production of <i>Ipomopsis aggregata</i>
Floral traits and nectar production of Ipomopsis aggregata were measured in response to water and phosphorus treatments applied to two morphotypes. Typical morphotypes underwent water and phosphorus treatments. Because stunted floral traits may be a response to drought stress, only water treatments
The Effects of Distance From a Yellow-Bellied Marmot Burrow on Plant Diversity
Mammal mounds have been found to have diverse effects on vegetation. The area around yellow-bellied marmot (Marmota flaviventris) burrows was examined for different morphospecies and plant cover to find if diversity decreased near a burrow. Morphospecies were identified to family to look for trends
Defensive strategy to nectar robbing in <i></i>Ipomopsis aggregata:<i></i> floral nectar as a tolerance trait
An earthflow that occurred in Gunnison County, Colorado created a natural laboratory to study plant succession. Plant succession and ants can effect the soil composition of grounds left bare and depleted of organic matter by the landslide. This study was conducted to examine if the described success
