Magnitude and Direction of Stream-Forest Community Interactions Change with Time Scale

Experimental and theoretical studies often yield conflicting evidence regarding the direction – positive or negative – or magnitude of biotic interactions.

Some Approaches to Accounting for Incidental Carcass Discoveries in Non-Monitored Years using the Evidence of Absence Model

The software tool “Evidence of Absence” (EoA) was published in 2014 to help interpret evidence that the number of fatalities of protected species (PS) that may occur at wind energy facilities has not exceeded a given threshold. The interpretation is based on the estimated probability of finding a PS carcass and the number of PS carcasses found during systematic surveys of the facilities.

Spawning Potential of Female Bull Trout in a River-Reservoir System

For coldwater species such as bull trout, water temperatures can affect energy reserves for growth, reproduction, or survival.

Mercury Bioaccumulation in the Chesapeake Bay Watershed

Despite the prevalence of mercury contamination in the Chesapeake Bay, large-scale patterns of mercury concentrations, and potential risks to fish, wildlife, and humans across the watershed, are poorly understood.

Examining Plant Traits to Discover Strategies of Coexisting Plants

Plant traits, such as leaf size and rooting depth, can affect plant performance and hence, how plants might respond to environmental change. Plant traits can be integrated, or correlated, with a particular functional plant response, such as how plants use water efficiently. Alternatively, plants can differentiate along multiple trait dimensions.

Patterns in Age Structure of Golden Eagles Wintering in Eastern North America

Wildlife behavior varies seasonally, particularly for long-distance migrants, and that variation can have substantial demographic consequences.

Learning From Real-World Experience to Understand Renewable Energy Impacts to Wildlife

A comprehensive analysis of how renewable energy facilities affect wildlife could inform efforts to predict and reduce these impacts. A team of researchers was asked to gain a better understanding of the actual environmental impacts of renewable energy generation on sensitive species and habitats in California.

Annotated Bibliography: Grazing Effects on Amphibians and Their Habitats

Livestock grazing is one of the most common land uses in the western United States, where multiple amphibians of conservation concern use habitats that are grazed.

Small-Scale Water Deficits After Wildfires Create Long-Lasting Ecological Impacts

Moisture deficit affects ecological processes and land management interventions, such as restoration of native vegetation.

Long Term Persistence of Aspen in Snowdrift-Dependent Ecosystems

Quaking aspen forests throughout much of the western United States have experienced significant mortality in recent decades, and one cause is moisture deficit.

Demographic Consequences of Human Stressors on Wildlife Populations

Predicting the ecological and conservation significances of human influences on wildlife populations is difficult. However, methodological developments can help make the transition from count-based field data on individuals to rate-based demographic estimates.
