Competition for nectar resources does not affect bee foraging tactic constancy
1. Competition alters animal foraging, including promoting the use of alternative resources. It may also impact how animals feed when they are able to handle the same food with more than one tactic. Competition likely impacts both consumers and their resources through its effects on food handling, b
The genome of the Margined White butterfly (Pieris macdunnoughii): sex chromosome insights and the power of polishing with PoolSeq data
We report a chromosome-level assembly for Pieris macdunnoughii, a North American butterfly whose involvement in an evolutionary trap imposed by an invasive Eurasian mustard has made it an emerging model system for studying maladaptation in plant-insect interactions.

Spatial and temporal patterns of floral inconstancy in plants and populations of Ipomopsis aggregata (Polemoniaceae)
To determine whether floral part numbers (merism) vary over time within inflorescences, we scored merism of the petals, sepals, stamens, and carpels of all flowers on the same 10 plants of Ipomopsis aggregata in three Colorado populations weekly through most of the 1984 flowering season. At least on
Colonization and reproduction of the epibiotic flagellate <i>Colacium vesiculosum</i> (Euglenophyceae) on <i>Daphnia pulex</i>
ABSTRACTThe epibiotic flagellate Colacium vesiculosum Pringsheim attaches to planktonic species of Daphnia in freshwater habitats. Previous studies found that prevalence (percentage of substrate organisms carrying attached epibionts) and intensity (number of attached epibionts on a given substrate o
Using Fission-Track Radiography Coupled with Scanning Electron Microscopy for Efficient Identification of Solid-Phase Uranium Mineralogy at a Former Uranium Pilot Mill (Grand Junction, Colorado)
At a former uranium pilot mill in Grand Junction, Colorado, mine tailings and some subpile sediments were excavated to various depths to meet surface radiological standards, but residual solid-phase uranium below these excavation depths still occurs at concentrations above background. The combinatio

Prototype Decision Support System for Operations on the Gunnison Basin with Improved Forecasts
Numerous studies have developed new methods for skillful long-lead seasonal streamflow forecasts, especially in the western United States, and most assume that the streamflow forecast skills translate into improved water resources decision making, but there has been little comprehensive demonstratio
Jointing in Sedimentary Rocks along the Grand Hogback Monocline, Colorado
Removal of strata dip-and-strike effects at each collecting station by rotation in three-dimensions increases resolution of data concerning the orientation of joint surfaces in sedimentary rocks. Contoured equal-area diagrams of unrotated and rotated joints illustrate the changes in joint plane pole
Captive‐rearing of Gunnison sage‐grouse from egg collection to adulthood to foster proactive conservation and recovery of a conservation‐reliant species
Gunnison sage‐grouse (Centrocercus minimus) are distributed across southwestern Colorado and southeastern Utah, United States. Their distribution has decreased over the past century and the species has been listed as threatened by the U.S. Fish and Wildlife Service. Reduced genetic diversity, small

Diverse cressdnaviruses and an anellovirus identified in the fecal samples of yellow-bellied marmots
Over that last decade, coupling multiple strand displacement approaches with high throughput sequencing have resulted in the identification of genomes of diverse groups of small circular DNA viruses. Using a similar approach but with recovery of complete genomes by PCR, we identified a diverse group
Do birds differentiate between white noise and deterministic chaos?
AbstractNoisy, unpredictable sounds are often present in the vocalizations of fearful and stressed animals across many taxa. A variety of structural characteristics, called nonlinear acoustic phenomena, that include subharmonics, rapid frequency modulations, and deterministic chaos are responsible f

Evolution and genomic basis of the plant penetrating ovipositor: a key morphological trait in herbivorous Drosophilidae
Herbivorous insects are extraordinarily diverse, yet are found in only one-third of insect orders. This skew may result from barriers to plant colonization, coupled with phylogenetic constraint on plant-colonizing adaptations. The plant-penetrating ovipositor, however, is one trait that surmounts ho
Cumulative reproductive costs on current reproduction in a wild polytocous mammal
The cumulative cost of reproduction hypothesis predicts that reproductive costs accumulate over an individual's reproductive life span. While short-term costs have been extensively explored, the prevalence of cumulative long-term costs and the circumstances under which such costs occur alongside or

Evolution of the alphaesterase duplication within the montana subphylad of the virilis species group of Drosophila
ABSTRACT Previous studies on linkage disequilibrium involving four tightly linked genes that code for the alpha-esterases of Drosophila montana suggest that these loci arose from a primitive esterase gene by gene duplication, Iollowed by tandem duplication (ROBERTS and BAKER 1973). We have examined

Using geochemical indicators to distinguish high biogeochemical activitiy in floodplain soils and sediments
This study develops a methodology to predict potential elevated rates of biogeochemical activity (microbial "hotspots") in subsurface environments by correlating microbial DNA and aspects of the community structure with the spatial distribution of geochemical indicators in subsURface sediments.
Salinity Trends in Surface Waters of the Upper Colorado River Basin, Colorado
AbstractDissolved‐solids data collected in the Upper Colorado River Basin upstream from Cameo, Colorado, and in the Gunnison River Basin were analyzed for trends in flow‐adjusted dissolved‐solids concentrations and loads for water years 1970 to 1993, 1980 to 1993, and 1986 to 1993. Trend results for
