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

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

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

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

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.

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 effects of a static external electric field on the ground state electronic structure of a porphine-quinone (PQ) complex have been studied by using density functional theory (DFT). The energies of the excited states have been calculated with time-dependent density functional theory (TDDFT) and wi

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

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

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.

Knowledge of ecosystem-size influences on river populations and communities is integral to the balancing of human and environmental needs for water. The multiple dimensions of dendritic river networks complicate understanding of ecosystem-size influences, but could be resolved by the development of

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

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

Abstract Evolutionary traps arise when organisms use novel, low‐quality or even lethal resources based on previously reliable cues. Persistence of such maladaptive interactions depends not only on how individuals locate important resources, such as host plants, but also the mechanisms underlying poo

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

Global climate change is shifting many species’ phenology and has created a number of key mismatches that threaten population persistence. Phenotypically plastic individuals have the ability to adjust their behaviour in response to environmental change. While phe- notypic plasticity may serve as a b

An author’s response to referees’ comments is a key component of the peer review process that affects whether a manuscript is accepted or rejected, the speed at which a manuscript moves through the review process, the workload of editors and referees, and the quality and clarity of published science
