Forecasting Summertime Shower Activity at Grand Junction, Colorado
Due to the lack of a dense network of reporting stations in the Grand Junction, Colorado area and the inadequate representation of shower activity by observations of rain at a single rain gage, certain arbitrary criteria were set up to define a “shower” day at Grand Junction. Relationships of a numb
THE EXCAVATION OF THE GRAND CANON OF THE COLORADO RIVER
GC skew is a measure of the strand asymmetry in the distribution of guanines and cytosines.GC skew favors R-loops, a type of three stranded nucleic acid structures that form upon annealing of an RNA strand to one strand of DNA, creating a persistent RNA:DNA hybrid.Previous studies show that GC skew
Notes on the Laramie Formation in Central Weld County, Colorado
Flying by night: Comparing nocturnal pollinator networks over time in the Colorado Rocky Mountains
Abstract Where climate is seasonal, such as in high‐altitude ecosystems, the occurrence and activity patterns of insect pollinators may vary with the varying occurrence of floral resources. This high turnover of species occurrence and interactions may lead to changes in the structure and properties
Phenological responses to multiple environmental drivers under climate change: insights from a long-term observational study and a manipulative field experiment
Abstract Climate change has induced pronounced shifts in the reproductive phenology of plants, with the timing of first flowering advancing in most species. Indeed, population persistence may be threatened by the inability to track climate change phenologically. Nevertheless, substantial variation e
The depredation of Mountain White-crowned Sparrow (<i>Zonotrichia leucophyrys oriantha</i>) nests by the golden-mantled ground squirrel (<i>Callospermophilus lateralis</i>) and long-tailed weasel (<i>Mustela frenata</i>)
The identities of avian nest predators remain unknown in many systems. The Mountain White-crowned Sparrow (Zonotrichia leucophrys oriantha) is a high-elevation ground-nesting passerine for which only 4 of 15 suspected nest predator species have been confirmed. In this short communication, we confirm
Connoisseur's Choice: Enargite, Longfellow Mine, Red Mountain District, San Juan County, Colorado
Are all things beautiful? Are all types equally beautiful when we abstract from our practical prejudices? If the reader gives his assent … we must declare that no object is essentially ugly. —Georg...
Stages and epochs of mineralization in the San Juan Mountains, Colorado, as shown at the Dunmore Mine, Ouray County, Colorado
The Dunmore lode is localized along a persistent fissure zone over two miles long and averaging nearly 100 feet in width along the length of the Dunmore claim. The fault in which the lode is located offset the pre-Cambrian quartzite and slate walls about 4,500 feet prior to deposition of the overlyi
The Reserved Rights Doctrine: Case Study Involving Black Canyon of the Gunnison National Park
Supreme Court has developed a legal doctrine -the "
Federal Agency Involvement in Western Renewable Energy Resource Decisions: Assessing the Views of Colorado County Commissioners
The core of the Black Canyon Computer Corporation
The author discusses his experiences with the GEC computer department, starting with the M236, a high speed 36-bit minicomputer. He discusses the GE 600 lineage, the GE 600/645 and paging, tape transport problems, and the end of the department.
Confluence: The Colorado River Compact's Centennial
Many thanks to Remi Bullock for that introduction and, more broadly, to the Potter
Species Composition and Hybridization among Native and Nonnative Catostomid Fishes in Two Streams of the Gunnison River Basin, Colorado
We report results from a 3-year field investigation to limit hybridization between native and nonnative suckers in 2 small tributaries of the Gunnison River basin, Delta County, Colorado. Upstream movement to spawning habitat was selectively impeded by picket weir in intermittent Cottonwood Creek. T
Do socio-cultural traits and other demographics affect outdoor recreation constraints? The case for Mesa County, Colorado
Physical activity from outdoor recreational pursuits is well known to be beneficial and has been encouraged by the US Surgeon General. Specific constraints, often reflected in sociocultural issues, can be impediments to individuals participating in outdoor recreational activities. Data were collecte
Early Records of Gilpin County, Colorado
Abiotic influences on continuous conifer forest structure across a subalpine watershed
Understanding the abiotic drivers of high-elevation forest physiognomy is essential for forecasting how mountain ecosystems will respond to emerging environmental pressures. Most prior studies of these relationships have relied on small samples of the full landscape, resulting in limited power to de
Observations of surface energy fluxes and meteorology in the seasonally snow-covered high-elevation East River watershed during SPLASH, 2021–2023
Rising Temperatures Reduce Colorado River Flow
Hotter conditions have played a much greater role in reducing flow during the ongoing Millennium Drought than in a mid-20th century drought.
