Preliminary testing of the role of exercise and predator recognition for bonytail and razorback sucker Preliminary testing of the role of exercise and predator recognition for bonytail and razorback sucker
Hatchery-reared juvenile, 45-cm TL) flathead catfish. Predator-naĂŻve juveniles (20- to 25-cm TL) exhibited no discernable preference when provided areas with and without (52 percent and 48 percent, n = 16 observations; 46 percent and 54 percent, n = 20 observations) large flathead catfish. However, once predation occurred, use of predator-free areas nearly doubled in two trials (36...

Using role analysis to plan for stakeholder involvement: a Wyoming case study Using role analysis to plan for stakeholder involvement: a Wyoming case study
Prior to implementing laws and policies regulating water, wildlife, wetlands, endangered species, and recreation, natural resource managers often solicit public input. Concomitantly, managers are continually seeking more effective ways to involve stakeholders. In the autumn of 1999, the Wyoming Game and Fish Department sought to develop a state management plan for its portion of the...

Negotiation Training Courses for Natural Resource Professionals Negotiation Training Courses for Natural Resource Professionals
FORT's Policy Analysis and Science Assistance Branch (PASA) has been conducting and publishing research on multi-party natural resource negotiation since the 1980s. This research has led to the development of basic and advanced negotiation training courses. Each course is two-and-a-half days. Both courses are a mix of lecture, hands-on training, and discussion. Please join us and other...

Response of western mountain ecosystems to climatic variability and change: The Western Mountain Initiative Response of western mountain ecosystems to climatic variability and change: The Western Mountain Initiative
Mountain ecosystems within our national parks and other protected areas provide valuable goods and services such as clean water, biodiversity conservation, and recreational opportunities, but their potential responses to expected climatic changes are inadequately understood. The Western Mountain Initiative (WMI) is a collaboration of scientists whose research focuses on understanding and

Natural history collections: A scientific treasure trove Natural history collections: A scientific treasure trove
Natural history collections play an indispensable and often overlooked role in the conservation and management of our Nation’s flora and fauna. Scientific specimens housed in museum collections not only open an important window into the current and past diversity of life on Earth, but also play a vital role in fueling cutting-edge scientific research in many disciplines. The U.S...

Impacts on water quality and biota from natural acid rock drainage in Colorado's Lake Creek watershed Impacts on water quality and biota from natural acid rock drainage in Colorado's Lake Creek watershed
Colorado's Lake Creek watershed hosts natural acid rock drainage that significantly impacts surface water, streambed sediment, and aquatic life. The source of the ARD is a group of iron-rich springs that emerge from intensely hydrothermally altered, unexploited, low-grade porphyry copper mineralization in the Grizzly Peak Caldera. Source water chemistry includes pH of 2.5 and dissolved...

The effect of multiple stressors on salt marsh end-of-season biomass The effect of multiple stressors on salt marsh end-of-season biomass
It is becoming more apparent that commonly used statistical methods (e.g. analysis of variance and regression) are not the best methods for estimating limiting relationships or stressor effects. A major challenge of estimating the effects associated with a measured subset of limiting factors is to account for the effects of unmeasured factors in an ecologically realistic matter. We used...

Autumn migration and selection of rock crevices as hibernacula by big brown bats in Colorado Autumn migration and selection of rock crevices as hibernacula by big brown bats in Colorado
Movements, distribution, and roosting requirements of most species of temperate-zone bats in autumn are poorly understood. We conducted the 1st radiotelemetry study of autumn migrations and prehibernation roost selection of bats in western North America. Big brown bats (Eptesicus fuscus, n = 55) in the Poudre River watershed, Colorado, moved from low-elevation summer ranges to high...

Rank score and permutation testing alternatives for regression quantile estimates Rank score and permutation testing alternatives for regression quantile estimates
Performance of quantile rank score tests used for hypothesis testing and constructing confidence intervals for linear quantile regression estimates (0 ≤ τ ≤ 1) were evaluated by simulation for models with p = 2 and 6 predictors, moderate collinearity among predictors, homogeneous and hetero-geneous errors, small to moderate samples (n = 20–300), and central to upper quantiles (0.50–0.99)...
