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

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
