I lead a team of scientists that develop tools and models to improve understanding of ecological systems and solve challenging problems in natural resource management. We primarily address questions related to species conservation, wildlife habitat, and restoration. We combine molecular methods, remote sensing, field studies, and statistical modeling. Our research team also develops data management and decision support systems to facilitate adaptive management, especially in western rangelands. We primarily work on issues affecting the Intermountain West and Great Basin regions of the U.S.

Loss and modification of habitat Loss and modification of habitat
Amphibians live in a wide variety of habitats around the world, many of which have been modified or destroyed by human activities. Most species have unique life history characteristics adapted to specific climates, habitats (e.g., lentic, lotic, terrestrial, arboreal, fossorial, amphibious), and local conditions that provide suitable areas for reproduction, development and growth...

Long-term observations of Boreal Toads at an ARMI apex site Long-term observations of Boreal Toads at an ARMI apex site
The U.S. Geological Survey’s Amphibian Research and Monitoring Initiative (ARMI) is a national project with goals to monitor the status and trends of amphibians, conduct research on causes of declines, and provide information and support to management agencies for conservation of amphibian populations. ARMI activities are organized around extensive inventories and place-based monitoring...

Amphibian responses to wildfire in the western united states: Emerging patterns from short-term studies Amphibian responses to wildfire in the western united states: Emerging patterns from short-term studies
The increased frequency and severity of large wildfires in the western United States is an important ecological and management issue with direct relevance to amphibian conservation. Although the knowledge of fire effects on amphibians in the region is still limited relative to most other vertebrate species, we reviewed the current literature to determine if there are evident patterns...

Compensatory effects of recruitment and survival when amphibian populations are perturbed by disease Compensatory effects of recruitment and survival when amphibian populations are perturbed by disease
The need to increase our understanding of factors that regulate animal population dynamics has been catalysed by recent, observed declines in wildlife populations worldwide. Reliable estimates of demographic parameters are critical for addressing basic and applied ecological questions and understanding the response of parameters to perturbations (e.g. disease, habitat loss, climate...

Molecular detection of vertebrates in stream water: A demonstration using rocky mountain tailed frogs and Idaho giant salamanders Molecular detection of vertebrates in stream water: A demonstration using rocky mountain tailed frogs and Idaho giant salamanders
Stream ecosystems harbor many secretive and imperiled species, and studies of vertebrates in these systems face the challenges of relatively low detection rates and high costs. Environmental DNA (eDNA) has recently been confirmed as a sensitive and efficient tool for documenting aquatic vertebrates in wetlands and in a large river and canal system. However, it was unclear whether this...

Great Basin Integrated Landscape Monitoring Pilot Summary Report Great Basin Integrated Landscape Monitoring Pilot Summary Report
The Great Basin Integrated Landscape Monitoring Pilot project (GBILM) was one of four regional pilots to implement the U.S. Geological Survey (USGS) Science Thrust on Integrated Landscape Monitoring (ILM) whose goal was to observe, understand, and predict landscape change and its implications on natural resources at multiple spatial and temporal scales and address priority natural...

Landscape genetics of high mountain frog metapopulations Landscape genetics of high mountain frog metapopulations
Explaining functional connectivity among occupied habitats is crucial for understanding metapopulation dynamics and species ecology. Landscape genetics has primarily focused on elucidating how ecological features between observations influence gene flow. Functional connectivity, however, may be the result of both these between‐site (landscape resistance) landscape characteristics and at...

Effects of amphibian chytrid fungus on individual survival probability in wild boreal toads Effects of amphibian chytrid fungus on individual survival probability in wild boreal toads
Chytridiomycosis is linked to the worldwide decline of amphibians, yet little is known about the demographic effects of the disease. We collected capture-recapture data on three populations of boreal toads (Bufo boreas [Bufo = Anaxyrus]) in the Rocky Mountains (U.S.A.). Two of the populations were infected with chytridiomycosis and one was not. We examined the effect of the presence of...

Hyperspectral analysis of columbia spotted frog habitat Hyperspectral analysis of columbia spotted frog habitat
Wildlife managers increasingly are using remotely sensed imagery to improve habitat delineations and sampling strategies. Advances in remote sensing technology, such as hyperspectral imagery, provide more information than previously was available with multispectral sensors. We evaluated accuracy of high-resolution hyperspectral image classifications to identify wetlands and wetland...

Non-native salmonids affect amphibian occupancy at multiple spatial scales Non-native salmonids affect amphibian occupancy at multiple spatial scales
Aim The introduction of non-native species into aquatic environments has been linked with local extinctions and altered distributions of native species. We investigated the effect of non-native salmonids on the occupancy of two native amphibians, the long-toed salamander (Ambystoma macrodactylum) and Columbia spotted frog (Rana luteiventris), across three spatial scales: water bodies...

Prescribed fires as ecological surrogates for wildfires: A stream and riparian perspective Prescribed fires as ecological surrogates for wildfires: A stream and riparian perspective
Forest managers use prescribed fire to reduce wildfire risk and to provide resource benefits, yet little information is available on whether prescribed fires can function as ecological surrogates for wildfire in fire-prone landscapes. Information on impacts and benefits of this management tool on stream and riparian ecosystems is particularly lacking. We used a beyond-BACI (Before, After...
