Species’ geographic range shifts towards higher latitudes and elevations are among the most frequently reported consequences of climate change. However, the role of species interactions in setting range margins remains poorly understood. We used cage experiments in ponds to test competing hypotheses

The study of mutualistic interaction networks has led to valuable insights into ecological and evolutionary processes. However, our understanding of network structure may depend upon the temporal scale at which we sample and analyze network data. To date, we lack a comprehensive assessment of the te

The loss of aboveground plant diversity alters belowground ecosystem function; yet, the mechanisms underpinning this relationship and the degree to which plant community structure and climate mediate the effects of plant species loss remain unclear. Here, we explored how plant species loss through e

Though rarely experimentally tested, biotic interactions have long been hypothesized to limit low-elevation range boundaries of species. We tested the effects of herbivory on three alpine-restricted plant species by transplanting plants below (novel), at the edge (limit), or in the center (core) of

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.

A winter orographic cloud seeding program has been conducted in the Gunnison, Colorado region for the past eight winter seasons. The intended target area is elevations above 9,000 feet MSL that provide streamflow to Blue Mesa Resevoir located in western Gunnison County. The goal of this operational

Sequence-stratigraphic study of the Cozzette and the Rollins Sandstone members, of the Mt. Garfield Formation of the Mesaverde Group, in the southern part of the Piceance basin (western Colorado), utilizes mainly well-log data along with limited outcrop data.

“The Rocky Mountain region has fascinated me ever since I traveled to Glacier and Yellowstone National Parks as a teenager, and saw for the first time such wonderful birds as ospreys, American dippers, and Lew­is’s woodpeckers.” This book is in part based on the author’s earlier Birds of the Rocky M

Social behavior consists of distinct and measurable social attributes. While many previous studies have categorized species as social or not, or quantified group size, studying the functional correlates of separate attributes may offer more specific insights into the adaptive value of sociality, but

My research investigates parental investment into offspring during reproduction in an invertebrate species that exhibits a unique combination of two life history traits, iteroparity (multiple reproductive bouts) and extended biparental care. I present a brief
