Understanding the processing of detritus by different macroinvertebrates in montane ponds is important because either directly or indirectly most energy and nutrients flow through the detrital pathway. Understanding the degree to which macroinvertebrate species vary in detrital processing is central

Climate change is increasing global temperatures, which forces many species to experience environments that they have not been previously exposed to. Ectotherms are particularly sensitive to temperature shifts, and previous research suggests that changes in phenology and habitat use can help species

Abstract The Fremont Butte meteorite was found near Fremont Butte, Colorado, in 1963. A single individual was found weighing 6.6 kg. It is an olivine‐hypersthene or L group chondrite showing brecciation and a small number of well formed chondrules and olivine phenocrysts.

This research aims to clarify the timing and mechanics behind a sixty kilometer- wide Bull’s Eye of exhumation in Colorado’s Elk and West Elk mountains that took place about 15-8 million years ago (Ma). To do this, I use the apatite (U-Th)/He low temperature thermochronology (AHe) technique to study

The biogeography of soil microbial communities is changing in response to increased anthropogenic disturbance, such as climate change. However, the response patterns of microbes to these rapid and accelerating changes is poorly quantified, especially when compared with our understanding of macroscop

This study investigated the impact of water availability and snowmelt timing on the species ​Ipomopsis aggregata. ​We looked to discover if ​I. aggregata’​ s traits were plastic, and if that plasticity was adaptive. The two questions we aimed to answer were: How does timing of snowmelt and level of

Stage-based population models are an important tool for quantifying the influence of biotic and abiotic factors on populations. Within studies of plant demography and life history, measuring and predicting biomass is an essential tool used to better understand a plant’s health and reproductive succe

Rising population and changing climate threaten to increase the risks posed by anthropogenic and geogenic metal contaminants to our freshwater resources. Increased human demand for freshwater coupled with altered hydrologic cycles will shift (bio)geochemical conditions in soils and sediments, potent

After a harrowing expedition down the Gunnison River through Colorado’s Black Canyon, Abraham Lincoln Fellows and his surveying partner, William W. Torrence, helped spur the construction of Gunnison Tunnel and the delivery of badly needed irrigation water to farmland.

Interactions between plants and pollinators are complex and a change to one can cause a significant impact on the other. Environmental perturbations like drought can alter plant- pollinator systems, changing the relative abundance of flower species, shifting species distribution, and decreasing flor

While many ecological studies have investigated the impacts of recreation and trails on wildlife, we lack an understanding of how wildlife respond to recreational trails that exhibit seasonally dynamic levels of human activity. We used camera traps to assess changes in the presence of mammals along
