Variability in weather and site properties affect fuel and fire behavior following fuel treatments in semiarid sagebrush-steppe. Variability in weather and site properties affect fuel and fire behavior following fuel treatments in semiarid sagebrush-steppe.
Fuel-treatments targeting shrubs and fire-prone exotic annual grasses (EAGs) are increasingly used to mitigate increased wildfire risks in arid and semiarid environments, and understanding their response to natural factors is needed for effective landscape management. Using field-data collected over four years from fuel-break treatments in semiarid sagebrush-steppe, we asked 1) how the...

Response of corvid nest predators to thinning: implications for balancing short- and long-term goals for restoration of forest habitat Response of corvid nest predators to thinning: implications for balancing short- and long-term goals for restoration of forest habitat
Forest thinning on public lands in the Pacific Northwest USA is an important tool for restoring diversity in forest stands with a legacy of simplified structure from decades of intensive management for timber production. A primary application of thinning in young ( 50-year-old) stands is to accelerate forest development to mitigate loss of late-seral habitat to decades of logging...

Predicting the spatial distribution of wintering golden eagles to inform full annual cycle conservation in western North America Predicting the spatial distribution of wintering golden eagles to inform full annual cycle conservation in western North America
Wildlife conservation strategies focused on one season or population segment may fail to adequately protect populations, especially when a species’ habitat preferences vary among seasons, age-classes, geographic regions, or other factors. Conservation of golden eagles (Aquila chrysaetos) is an example of such a complex scenario, in which the distribution, habitat use, and migratory...

Demography with drones: Detecting growth and survival of shrubs with unoccupied aerial systems Demography with drones: Detecting growth and survival of shrubs with unoccupied aerial systems
Large-scale disturbances, such as megafires, motivate restoration at equally large extents. Measuring the survival and growth of individual plants plays a key role in current efforts to monitor restoration success. However, the scale of modern restoration (e.g., >10,000 ha) challenges measurements of demographic rates with field data. In this study, we demonstrate how unoccupied aerial...

Evaluating spatial coverage of the greater sage-grouse umbrella to conserve sagebrush-dependent species biodiversity within the Wyoming basins Evaluating spatial coverage of the greater sage-grouse umbrella to conserve sagebrush-dependent species biodiversity within the Wyoming basins
Biodiversity is threatened due to land-use change, overexploitation, pollution, and anthropogenic climate change, altering ecosystem functioning around the globe. Protecting areas rich in biodiversity is often difficult without fully understanding and mapping species’ ecological niche requirements. As a result, the umbrella species concept is often applied, whereby conservation of a...

Flash drought: A state of the science review Flash drought: A state of the science review
In the two decades, since the advent of the term “flash drought,” considerable research has been directed toward the topic. Within the scientific community, we have actively forged a new paradigm that has avoided a chaotic evolution of conventional drought but instead recognizes that flash droughts have distinct dynamics and, particularly, impacts. We have moved beyond the initial debate...

The geographic extent of bird populations affected by renewable-energy development The geographic extent of bird populations affected by renewable-energy development
Bird populations are declining globally. Wind and solar energy can reduce emissions of fossil fuels that drive anthropogenic climate change, yet renewable-energy production represents a potential threat to bird species. Surveys to assess potential effects at renewable-energy facilities are exclusively local, and the geographic extent encompassed by birds killed at these facilities is...

Contrasting demographic responses under future climate for two populations of a montane amphibian Contrasting demographic responses under future climate for two populations of a montane amphibian
For species with complex life histories, climate change can have contrasting effects for different life stages within locally adapted populations and may result in responses counter to general climate change predictions. Using data from two, 14-year demographic studies for a North American montane amphibian, Cascades frog (Rana cascadae), we quantified how aspects of current climate...

Variable climate-growth relationships of quaking aspen (Populus tremuloides) among Sky Island mountain ranges in the Great Basin, Nevada, USA Variable climate-growth relationships of quaking aspen (Populus tremuloides) among Sky Island mountain ranges in the Great Basin, Nevada, USA
The Great Basin is an arid province located in the interior western United States. The region encompasses millions of hectares and quaking aspen (Populus tremuloides Michx.) forests comprise a minor portion of the total area. However, montane aspen forests play a disproportionately large role in providing ecosystem services in the region, including water retention, biodiversity, wildlife...

The haunting raptor: Yellowstone’s golden eagles The haunting raptor: Yellowstone’s golden eagles
For many who live in North America, when picturing an eagle, the image of a large magnificent bird with a distinct white head and tail comes to mind. Rightfully, the bald eagle has garnered much attention as a national symbol of the United States (US), nearly brought to extinction from widespread organochlorine pesticide use (e.g., DDT, dichloro- diphenyl- trichloroethane; Anderson 1972...
