Resolution of the large-scale kinematics of the Pennsylvanian-Permian Ancestral Rocky Mountains requires definition of sense of slip and time of movement on specific faults within the system of fault-bounded basins and uplifts (e.g., Paradox basin, Uncompahgre uplift). Along an east-west–striking se

Recruitment of juveniles is an important vital rate that influences population growth and is fundamental to understanding trends in population size. Estimates of recruitment are often focused on the period just after hatching (prefledgling stage), which is typically the lowest survival period and of

Abstract Insect herbivores that are tended by ants exhibit a range in host plant use from specialists to extreme generalists. Potential factors that may influence relative suitability of different host plants include the presence or absence of ants and the size of aggregations formed by nymphs feedi

The long-term release of uranium from residual sources at former uranium mill sites was often not considered in prior conceptual and numerical models, as contaminant removal focused on meeting radiological standards. To determine the reactive transport parameters, column tests were completed with va

Evaluation of long-term temporal and spatial climatic change in mountainous regions is a critical challenge because of the interactive effects of multiple land and climatic factors and processes. Here we present the application of the statistical framework to the assessment of changes of climatic co

AbstractEvapotranspiration is arguably the least quantified component of the hydrologic cycle. We propose two complementary strategies for estimation of evapotranspiration rates and root water uptake profiles from soil‐moisture sensor‐array data. One is our implementation of ensemble Kalman filter (

Experimental manipulation of the presence of ants in two different years indicated that the existence of ants had a positive effect on nymph numbers on both host plants, Chrysothamnus viscidiflorus and Wyethia spp, but not on WyethIA spp.

Background: The enzyme phosphoenolpyruvate carboxykinase, PEPCK, occurs in its guanosine-nucleotide-using form in animals and a few prokaryotes. We study its natural genetic variation in Colias (Lepidoptera, Pieridae). PEPCK offers a route, alternative to pyruvate kinase, for carbon skeletons to mov

Reconstructing Pleistocene glaciation timing and extent is vital for understanding paleoclimate. Whereas late Pleistocene glaciation has been studied extensively in western North American mountain ranges, the glacial history of the western Elk Range in Colorado remains understudied, particularly in

At the 2008 ASMR conference, data from the initial two months of operation of a U.S. EPA pilot biochemical reactor (BCR) was reported. The BCR was designed and constructed in August, 2007 to treat mining influenced water (MIW) emanating from an adit at a remote site in southern Colorado. The origina

Life history trade-offs are one of the central tenets of evolutionary demography. Trade-offs, depicting negative covariances between individuals' life history traits, can arise from genetic constraints, or from a finite amount of resources that each individual has to allocate in a zero-sum game betw
