Comparisons of invertebrate populations of the herb layers of the alpine and subalpine zones
Morphological variation in <i>Castilleja</i>
A comparative study of grazing effects in sagebrush lands
Amphibian populations surrounding the Rocky Mountain Biological Laboratory: risk assessment and management strategies
The natural history and conservation status of <i>Nicrophorus americanus</i> and <i>Nicrophorus investigator</i>
Volatile organic compounds as signals for pollinators and their consistency across years
Volatile organic compounds (VOCs) are emitted by every part of a plant and are believed to work as possible olfactory signals, drawing in pollinators and antagonists. This study was designed to address whether VOCs served as a signal to pollinators, indicating the size of the nectar reward. This par
Environmental and Genetic Effects of Elevation on Plant Defense
Plant communities are shaped by their interactions with biotic and abiotic factors in their environment, including herbivores. In response to pressures from herbivores, plants develop a variety of physical and chemical defenses to protect themselves. The investment that plants make in these defenses
Effects of sewage effluent discharge on aquatic invertebrate diversity and abundance in the Slate River, Colorado
Carbon Dioxide Efflux and Storage in Small, Drying Alpine Ponds
Climate change is expected to influence the drying regimes of small ponds, impacting their carbon cycling capabilities and potentially inducing unprecedented pond drying that could lead to higher greenhouse gas efflux rates. Small ponds are already known to release disproportionately high amounts of
Lateralized Function Without Lateralization
In many vertebrates, the right hemisphere/left visual field is used to process information about threats while the left hemisphere/right visual field is used to process information about conspecifics. This is referred to as hemispheric lateralization. But prey that are too predictable in their respo
Phenology and Phenotypic Variation of <i>Thlaspi arvense</i> Along an Elevational Gradient
Thlaspi arvense, a non-native plant in the Brassicaceae family, was first introduced to the Gunnison valley of Colorado in the 1800s (Chew 1975). Long-term studies done at the Rocky Mountain Biological Laboratory suggest the presence of T. arvense has negative impacts on the fitness of native Pieris
Effects of nutrient addition on flower morphology and nectar production in <i>Ipomopsis aggregata</i>
Do the differing pollen foraging strategies of <i>Megachile sp.</i> and <i>Bombus spp.</i> result in differing pollen removal and deposition rates in <i>Lupinus bakeri</i>?
Mutualistic interactions between flowering plants and bees are a pairwise interaction, but exist in a network of similar interactions (Bronstein, 2001). The outcomes of these interactions differ, for example, the costs and benefits for flowering plants caused by floral visitors (Bronstein, 2001). Lu
Factors that affect territory size in Mountain White-Crowned Sparrows (<i>Zonotrichia leucophrys oriantha</i>)
Male songbirds sing on the edge of their territory to warn away competing males. The mountain white-crowned sparrow (Zonotrichia leucophrys oriantha) prefers to sing on the edge of willows and spruce trees. High quality territory is determined by the availability of food, water and shelter. Meanwhil
Investigating alpine plant community responses to simulated warming and dominant species removal at a low and high elevation in the Colorado Rocky Mountains
Effect of Road Dust Deposition on the Floral Lifespan of Scarlet gilia, <i>Ipomopsis aggregata</i>
The Rocky Mountains are one of the world’s most diverse areas in all of Western United States. Like most wonders of the world, the Rocky Mountains are also subjected to unpaved roads, and these roads often produce fine particulates of dirt that are able to rise into the air with ease. In this study,
