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
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
Shifting macroecological patterns and static theory failure in a stressed alpine plant community
Abstract Accumulating evidence suggests that ecological communities undergoing change in response to either anthropogenic or natural disturbances exhibit macroecological patterns that differ from those observed in similar types of communities in relatively undisturbed sites. In contrast to such cros
Can rarefaction be used to estimate song repertoire size in birds?
Abstract Song repertoire size is the number of distinct syllables, phrases, or song types produced by an individual or population. Repertoire size estimation is particularly difficult for species that produce highly variable songs and those that produce many song types. Estimating repertoire size is
The evolution of wing color: male mate choice opposes adaptive wing color divergence in <i>Colias</i> butterflies
Correlated evolution of mate signals and mate preference may be constrained if selection pressures acting on mate preference differ from those acting on mate signals. In particular, opposing selection pressures may act on mate preference and signals when traits have sexual as well as nonsexual funct
Movement and Growth of Juvenile Colorado Pikeminnows in the San Juan River, Colorado, New Mexico, and Utah
AbstractUnderstanding patterns of animal distribution and abundance based on their movements is important to identify the habitats and factors that maximize growth and reproductive success. Despite stocking age‐0 hatchery‐reared Colorado Pikeminnow Ptychocheilus lucius for over 10 years in the San J
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.

Water budgets of montane-mesic and lowland-xeric populations of yellow-bellied marmots
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
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
From Insects to Frogs, Egg–Juvenile Recruitment Can Have Persistent Effects on Population Sizes
Understanding what regulates population sizes of organisms with complex life cycles is challenging because limits on population sizes can occur at any stage or transition. We extend a conceptual framework to explore whether numbers of successfully laid eggs determine densities of later stages in ins
Carbon Dioxide Concentrations and Efflux from Permanent, Semi-Permanent, and Temporary Subalpine Ponds
Small ponds account for a disproportionately high percentage of carbon dioxide emissions relative to their small surface area. It is therefore crucial to understand carbon flow in these ponds to refine the current global carbon budget, especially because climate change is affecting pond hydrology. H
CLAST‐LADEN MELT‐ROCK FRAGMENT IN THE ADAMS COUNTY, COLORADO, H5 CHONDRITE
The Adams County, Colorado, H5 chondrite contains a lithic fragment, 1 cm in size, that is texturally and mineralogically quite different from the chondritic host. It is composed of: a groundmass of fine‐grained euhedral to subhedral olivine (3–15 μm) and interstitial glass enclosing larger olivine

An Annotated List of the Birds of Mesa County, Colorado
Marmots do not consistently use their left eye to respond to an approaching threat but those that did fled sooner
In many vertebrates, the brain's right hemisphere which is connected to the left visual field specializes in the processing of information about threats while the left hemisphere which is connected to the right visual field specializes in the processing of information about conspecifics. This is ref
Selection of floral traits by pollinators and seed predators during sequential life history stages
AbstractOrganismal traits often influence fitness via interactions with multiple species. That selection is not necessarily predictable from pairwise interactions, such as when interactions occur during different life cycle stages. Theoretically, directional selection during two sequential episodes
