Change in dominance determines herbivore effects on plant biodiversity Change in dominance determines herbivore effects on plant biodiversity
Herbivores alter plant biodiversity (species richness) in many of the world’s ecosystems, but the magnitude and the direction of herbivore effects on biodiversity vary widely within and among ecosystems. One current theory predicts that herbivores enhance plant biodiversity at high productivity but have the opposite effect at low productivity. Yet, empirical support for the importance of...

Understanding the captivity effect on invertebrate communities transplanted into an experimental stream laboratory Understanding the captivity effect on invertebrate communities transplanted into an experimental stream laboratory
Little is known about how design and testing methodologies affect the macroinvertebrate communities that are held captive in mesocosms. To address this knowledge gap, we conducted a 32‐d test to determine how seeded invertebrate communities changed once removed from the natural stream and introduced to the laboratory. We evaluated larvae survival and adult emergence in controls from 4...

A dirty dozen ways to die: Metrics and modifiers of mortality driven by drought and warming for a tree species A dirty dozen ways to die: Metrics and modifiers of mortality driven by drought and warming for a tree species
Tree mortality events driven by drought and warmer temperature, often amplified by pests and pathogens, are emerging as one of the predominant climate change impacts on plants. Understanding and predicting widespread tree mortality events in the future is vital as they affect ecosystem goods and services provided by forests and woodlands, including carbon storage needed to help offset...

Estimating the probability of movement and partitioning seasonal survival in an amphibian metapopulation Estimating the probability of movement and partitioning seasonal survival in an amphibian metapopulation
Movement of individuals has been described as one of the best studied, but least understood concepts in ecology. The magnitude of movements, routes, and probability of movement have significant application to conservation. Information about movement can inform efforts to model species persistence and is particularly applicable in situations where specific threats (e.g., disease) may...

El Niño/Southern Oscillation-driven rainfall pulse amplifies predation by owls on seabirds via apparent competition with mice El Niño/Southern Oscillation-driven rainfall pulse amplifies predation by owls on seabirds via apparent competition with mice
Most approaches for assessing species vulnerability to climate change have focused on direct impacts via abiotic changes rather than indirect impacts mediated by changes in species interactions. Changes in rainfall regimes may influence species interactions from the bottom-up by increasing primary productivity in arid environments, but subsequently lead to less predictable top-down...

Novel landscape elements within natural gas fields increase densities but not fitness of an important songbird nest predator Novel landscape elements within natural gas fields increase densities but not fitness of an important songbird nest predator
Identifying the elements within human-altered landscapes most associated with population and community changes is critical for conservation and management of sensitive species. We investigated which features of habitat change from natural gas development best explained the density of deer mice (Peromyscus maniculatus), an important nest predator of declining sagebrush-obligate songbirds...

Identifying management-relevant research priorities for responding to disease-associated amphibian declines Identifying management-relevant research priorities for responding to disease-associated amphibian declines
A research priority can be defined as a knowledge gap that, if resolved, identifies the optimal course of conservation action. We (a group of geographically distributed and multidisciplinary research scientists) used tools from nominal group theory and decision analysis to collaboratively identify and prioritize information needs within the context of disease-associated amphibian decline...

Compilation and assessment of resource values and hazards to inform transportation planning and associated land-use planning Compilation and assessment of resource values and hazards to inform transportation planning and associated land-use planning
Land-use planning has an important role in local, regional, State, and Federal land management, and planning efforts can benefit from consistent, spatially explicit information that can help guide priorities and decisions. The credibility and relevance of information used to inform planning activities depends on the availability of consistent information about the resources and values of...

Improving confidence by embracing uncertainty: A meta-analysis of U.S. hunting values for benefit transfer Improving confidence by embracing uncertainty: A meta-analysis of U.S. hunting values for benefit transfer
Recreational hunting in the United States has traditional and cultural importance, and generates substantial economic benefits to individual hunters themselves. This paper conducts a meta-analysis of existing nonmarket valuation estimates for hunting in the United States to explore sources and implications of variation and uncertainty in these estimates. A multi-level meta-regression...

Relationships between landscape constraints and a crayfish assemblage with consideration of competitor presence Relationships between landscape constraints and a crayfish assemblage with consideration of competitor presence
Aim Crayfish are globally diverse and one of the most important taxa in North American streams. Despite their importance, many species are of conservation concern and efforts to improve conditions are limited. Here, we address two major impediments to improving conditions: (a) our lack of knowledge of the interplay among natural landscape and human-induced changes; and (b) a very limited

Quantifying climate sensitivity and climate-driven change in North American amphibian communities Quantifying climate sensitivity and climate-driven change in North American amphibian communities
Changing climate will impact species’ ranges only when environmental variability directly impacts the demography of local populations. However, measurement of demographic responses to climate change has largely been limited to single species and locations. Here we show that amphibian communities are responsive to climatic variability, using >500,000 time-series observations for 81...

Resistance to deltamethrin in prairie dog (Cynomys ludovicianus) fleas in the field and in the laboratory Resistance to deltamethrin in prairie dog (Cynomys ludovicianus) fleas in the field and in the laboratory
Sylvatic plague poses a substantial risk to black-tailed prairie dogs (Cynomys ludovicianus) and their obligate predator, the black-footed ferret (Mustela nigripes). The effects of plague on prairie dogs and ferrets are mitigated using a deltamethrin pulicide dust that reduces the spread of plague by killing fleas, the vector for the plague bacterium. In portions of Conata Basin, Buffalo...
