Nest Distribution of <i> Bombus </i> spp. Across Different Habitat Types
Despite bumble bees’ critical importance as pollinators throughout the montane regions of Colorado, little research has been done on their nesting habits. In order to conserve the populations of Bombus spp. in the West, better knowledge of their nest density and nesting habitats is needed. I hypothe
Effects of Temperature on Voltinism in Subalpine Potter Wasps (Vespidae: Eumeninae)
Voltinism, the number of generations produced per year, is under both genetic and environmental control in insects. The rapid temperature increases associated with climate change could distort the information insects are obtaining from environmental cues and possibly alter the number of generations
The occurrence of annuals and perennials in a subalpine system
Puddling behavior in butterflies
Foraging behavior in <i>Bombus</i> spp
Plant selection of mycorrhizal symbionts in response to abiotic stress.
Effects of Bombus removals on Diptera Foraging Behaviors.
The effects of light intensity on ant-aphid mutualisms on Osha (Ligusticum porteri).
Is coat color associated with boldness and docility in marmots?
How do above and belowground grass-fungus symbioses change over elevational gradients in mountainous Colorado?
Plants and fungi are closely associated and likely have been since terrestrial ecosystems were first inhabited. These symbiotic relationships have taken two main forms: internal aboveground symbionts known as endophytes, and belowground root associated fungi, the most common of which are mycorrhizal
Spatial distribution and nest site selection in a Colorado cavity-nesting bird community
Linking pollinator behavior and pollen receipt in Ipomopsis aggregata
What was the paleo-discharge required to transport large Maroon Formation boulders during the late Pleistocene in the Cement Creek watershed?
Development and structure of boldness and aggression in yellow-bellied marmots
The ontogeny of personality traits is crucial to understanding their ecological significance but has not yet been well-studied. We examined the development of two traits that are commonly correlated in a syndrome, boldness and aggression, in a long-term study of yellow-bellied marmots (Marmot flaviv
Testing how density affects caddisfly distribution along a detritus quality gradient
As ecosystems continue to change, the ability to find high-quality habitats is becoming a valuable skill. Caddisflies are often found in pond environments with a variety of habitat qualities, such as food (detritus) quality. Asynarchus nigriculus, being highly mobile and having a unique dietary need
The effect of cytotype on radial growth rate in quaking aspen (<i> Populus tremuloides </i>) across environmental gradients
Quaking aspen (Populus tremuloides) trees are a foundation species that is widely distributed across all North America. Since the early 2000s, high levels of mortality have been observed in these forests. In recent decades, many quaking aspen forests have been experiencing high mortality rates. This
Behavioral responses of white-crowned sparrows (Zonotrichia leucophrys) to synthesized nonlinear phenomena
Costs and benefits of an ant-membracid mutualism in the absence of predation
Temperature Selection in the Arizona Tiger Salamander (<i> Ambystoma mavortium nebulosum </i>)
High-elevation ecosystems are experiencing rapid warming and severe impact of global climate change. The Arizona Tiger Salamander (Ambystoma mavortium nebulosum) occurs in high elevation ponds in the West Elk Mountains of Colorado and offers a compelling system to test context-dependent responses to
Trade-offs associated with food availability and predator avoidance behavior of a stream mayfly
We studied the effects of food availability and predator cues on mayflies at the Rocky Mountain Biological Laboratory (RMBL) in Gothic, CO. Organisms in a wide variety of ecological systems must deal with trade-offs between functions necessary to sustain their populations. Specifically, we were inte
