Elucidating the influence of a nectar yeast and nectar robbing on bumblebee foraging tactic constancy
Animal pollination services are vital for plant reproduction, with approximately 90% of plant species benefitting from this mutualistic relationship. Nectar is one of the most common floral rewards offered by plants in exchange for pollination services. Similarly, nectar is vital for bumbles as they
6PGD2 allozyme differentiation in Ipomopsis aggregata: a biochemical adapatation to soil moisture
Polymorphism in <i>Aquilegia caerula</i>
Effects of soil moisture and temperature on plant palatability and herbivore plant preference
Climate change is predicted to lead to increased water and temperature stress for plants. Reduced soil moisture and higher temperatures have the potential to impact plant growth, development, and survival. Changes in plant physiology due to climate change may also impact insect herbivores. Herbivore
Impacts of brood parasites, floral abundance, and bee age on maternal investment in a solitary bee, <i> Osmia iridis </i>
Parents can adjust both the size and number of offspring they produce in order to maximize their own fitness payoff (Smith & Fretwell 1974). Optimal parental investment is dependent in part on likelihood of offspring survival, which is impacted by predation and parasitism. When risk of predation or
Using GIS techniques to test a model of the coexistence of the golden-mantled ground squirrel, Callospermopholis lateralis, and the least chipmunk, Tamias minimus
Predator-prey interactions extend beyond direct predation and can influence prey behavior and habitat use. This “ecology of fear” has been studied in a wide variety of taxa, and differences in perceived predation risk have been demonstrated to impact species coexistence. Previous research (Smith 199
Elevation Does Not Predict Density Dependent Population Dynamics in Valeriana edulis
Density dependence—the impact of neighbors on the survival, growth, or reproduction of individuals—strongly impacts the size and dynamics of populations. However, it is unknown how the effects of density dependence vary across species ranges, which will be integral knowledge in the face of climate c
Plant Bioassay Testing Soil Quality Following Carrion Insect Activity
The decomposition of animal carrion, particularly small animals that are used as a breeding resource for carrion insects, is little studied but is likely to be a major component of nutrient cycling in many ecosystems. This project focuses on how carrion insects affect small vertebrate carrion decomp
Social transmission of a novel foraging trait in yellow-bellied marmots
Social transmission of novel behaviors can be an adaptive technique to rapidly and flexibly change responses to the surrounding environment. Although the dynamics of social transmission have been studied in highly social birds, primates, otters, and bats, we lack a solid understanding of the dynamic
Richness and distribution of insects on a slope frequently disturbed by avalanches
The variation in tree growth performance relative to a climate change along an elevation gradient
How Does Streambed Heterogeneity, Light Intensity, and Near-bed Current Influence Algal Accrual, Ash Free Dry Mass, and Macroinvertebrate Richness, and Abundance?
Research in stream ecology has become imperative to protect the ecosystem from natural and human induced disturbances. By indulging in the variation of substrate makeup, light intensity, and current velocity, we can evaluate the composition of living organisms as well as the nutrients around them. T
