A note comparing the primary structure of the arctic ground squirrel and the yellow-bellied marmot hemoglobin B chains
Hemoglobin β chains were isolated from both the arctic ground squirrel (Citellus parryii undulatus) and the yellow-bellied marmot (Marmota flaviventris). After various enzymatic and chemical cleavages, the primary structures of these β chains were determined. Only one sequence difference was found b
How diploidization turned a tetraploid into a pseudotriploid
The Fremont Butte, Washington Co., Colorado, Meteorite
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.
Antibody development to identify components of IIS and mTOR signaling pathways in lepidopteran species, a set of non-model insects
Nutritional stress impacts many insect species that have differing reproductive strategies and life histories, yet it is unclear how nutrient-sensing signaling pathways mediate tissue-specific responses to changes in dietary input. In Drosophila melanogaster, insulin/insulin-like growth factor (IIS)
Urban Water Conservation Success in the Colorado River Basin
In the past few decades, cities in Arizona, Colorado, and Nevada have vastly increased their water use efficiency. They’ve also learned lessons that can inform other cities’ efforts.

Ecological patterns in glucosinolate content of a native mustard, Cardamine cordifolia, in the Rocky Mountains
Wintertime Supercooled Liquid Water Flux over the Grand Mesa, Colorado
Supercooled liquid water (SLW) and wind measurements were made over the Grand Mesa of western Colorado during the period late January through March, 1986. Observations were obtained with an instrumented aircraft, a tower-mounted icing rate meter, and an acoustical sounder. These data were used to es
Population Growth and Municipal Water Insecurity in Mesa County, Colorado
The purpose of this project was to utilize GIS software to develop a population and daily domestic water resource requirement analysis for Mesa County, Colorado by answering the question of what municipalities within the county have the highest potential of developing water insecurities between the
Control of Colorado Potato Beetle in the Red River Valley, Grand Forks, ND, 1994
Abstract Potatoes were planted 17 May at the Research Farm of the Red River Valley Potato Growers Association. Plots were four rows wide, 60 ft long, with 38 in rows and 12 in between plants. Plots were separated on all sides by 6.3 ft of cultivated soil. The experiment had a complete randomized plo
Irish Potato, Colorado Potato Beetle Control, Johnston County, 1979
Abstract 'Superior' Irish potatoes were planted on Mar 29, near Benson, NC. Single row plots 7-ft long were replicated 4 times in a randomized complete block design with 2-ft alleys between replications. A pretreatment stand count and defoliation rating was made on May 15. Rating was based on 0 - no
Revisions to the Wanakah Formation in and around Ouray County, Colorado
A well-defined type section and consistent nomenclature are fundamental requirements for successful correlation of stratigraphic units and subsequent accurate paleogeographic reconstructions. The exact location of the original type section of the Middle Jurassic Wanakah Formation of the eastern Colo
The use of the stonefly, Pteronarcys californica Newport, as a measure of biologically available cadmium in a high altitude river system, Colorado, USA
Analysis of pollinator foraging: tests for non-random behavior
1. A standardized protocol for analysing the behaviour of pollinators foraging on more than one plant type (species or morph) is needed. 2. A protocol is presented in which the first step is to test whether foraging trips are homogeneous in the frequency of visits to each plant type, or whether ther
