Plasticity in Ipomopsis flower color and nectar production over space and time in response to water availability
Climate change is altering water availability in subalpine ecosystems. Shifts in snowmelt timing and summer monsoonal precipitation, which alter soil moisture, have the capacity to elicit plastic responses in plants. Plasticity in floral traits such as nectar production and flower color can impact p
Scent marking behavior in <i>Ochotona princeps</i>
Mapping the range shifts of East River Valley caddisflies <i> (Trichoptera) </i>
Range shifts occur when all individuals of a species or population move from a previously- habitable area to a newly-habitable area in response to changing environmental conditions. Climate- induced range shifts are well-documented for certain regions, biomes, and taxa, but large knowledge gaps exis
A preliminary study of <i>Ranunculus inamoenus</i>, <i>alpeophilus</i> and <i>eschscholtzii</i>
Effects of Microclimate on the regeneration of Quaking Aspens, <i>Populus tremuloides</i>
Populus tremuloides is a keystone species found throughout North America. P. tremuloides aids the regeneration of eco systems, however as climate changes, the health of P. tremuloides is changing. P. tremuloides populations are on the decline in the American southwest, and with time it could affect

Gregariousness in chrysomelid beetle larvae
Analysis of growth patterns in Conifer stands present in Gothic town
Forest ecology research is being revolutionized with the advent of remote sensing. Remote sensing is more accurate and reliable than previous methods for assessing forest dynamics, so it is important to generate workflows for assessing them. The forests of the Gothic townsite are an underutilized su
Does it stay or does it go: exploring seasonal influences on nutrients across topography in a Colorado mountain watershed
Climate change is a current issue that impacts ecosystems and the natural processes within them. Through the variance of factors such as, temperature, precipitation and hydrology due to climate change key processes such as nutrient cycling are affected. This study focused on the movement of nitrogen
Is flight initiation distance associated with longer-term survival in yellow-bellied marmots (<i> Marmota flaviventer </i>)?
The distance at which animals move away from threats, flight initiation distance (FID), is often used to study antipredator behavior and risk assessment. Variation in FID is explained by a variety of internal and external biotic and physical factors, including anthropogenic activities. Most prior st

Effect of altitude on <i>Frasera speciosa</i> populations
Hot and Cold: Assessing the Thermal Limitations of Bumble Bees in a Changing Climate
To understand bumblebee thermal limitations a controlled experient was built and tested in different environmental conditions to determine the most stable form of conducting upper and lower thermal trials in the field. The study was conducted at field sites located at the Rocky Mountain Biological L

Dynamics of male inconstancy in <i> Valeriana edulis </i> in the abiotic and mating environment
This study investigated inconstancy in the sex-expression of male flowers across populations of Edible Valerian (Valeriana edulis) as well as potential drivers of its variation. Though Valeriana edulis is dioecious (individuals typically have separate sexes), plants showing dominant male sex-express
