Riparian zones often provide more food or nesting resources than surrounding ecosystems and thus support more species or a greater abundance of birds. However, the extent to which the positive effects of riparian zones extend into adjoining habitats has rarely been investigated. We examined bird spe

AbstractEvaluation of population dynamics for rare and declining species is often limited to data that are sparse and/or of poor quality. Frequently, the best data available for rare bird species are based on large‐scale, population count data. These data are commonly based on sampling methods that

The historical distribution of Gunnison Sage-Grouse (Centrocercus minimus) in Colorado is described based on published literature, observations, museum specimens, and the known distribution of sagebrush (Artemisia spp.). Historically, Gunnison Sage-Grouse were widely but patchily distributed in up t

Myxobolus cerebralis, the causative agent of whirling disease, has been a major contributor to the loss of young trout in numerous streams within the Intermountain West (Colorado, Idaho, Montana, Utah, Wyoming). Currently there are no effective management procedures for mitigating the effects of thi

Ecological theory holds that edge effects influence species composition and diversity along both anthropogenic and natural forest edges. These ecotonal zones provide abundant microhabitats and opportunity for increased biodiversity. Abiotic factors such as temperature, soil moisture and soil water-h

AbstractGunnison sage‐grouse (Centrocercus minimus) is a species of special concern and is currently considered a candidate species under Endangered Species Act. Careful management is therefore required to ensure that suitable habitat is maintained, particularly because much of the species' current

The Global list of endangered species of flora and fauna is growing, with the most highly specialized species often at ‘critically endangered’ status. Managing these populations effectively involves numerous and varied organizations, conflicting motivations, arbitrary anthropogenic boundaries and of

AbstractDams have reduced distribution of the endangered Colorado pikeminnow Ptychocheilus lucius in the upper Colorado River basin: low‐head diversion dams blocked upstream passage and large dams inundated free‐flowing segments and cooled downstream reaches with deep‐water releases. To date, range

The results of a long-term experimental warming study, in a montane meadow in the Rocky Mountains of Colorado, have shown that Artemisia tridentata (Common Sagebrush) is likely to increase in abundance under climate change, as perennial forb species decrease in abundance. This change in species comp

Primers for 10 microsatellite loci developed specifically to amplify low quantity and quality DNA for Gunnison Sage-grouse were found to have levels of variability ranging from two to seven alleles, although one locus revealed significant departures from Hardy–Weinberg equilibrium.

Introduction: Fuels treatments have occurred within the Gunnison Basin for nearly 30 years. Since 1976, approximately 120,000 acres have been treated. Emphasis was on disposal of slash from timber sales, prescribed burning for wildlife and livestock improvements as well as restoration of threatened
