ABSTRACT The sagebrush ( Artemisia spp.) ecosystem is one of the largest ecosystems in western North America providing habitat for species found nowhere else. Sagebrush habitats have experienced dramatic declines since 1950s, mostly due to anthropogenic disturbances. greater sage‐grouse Centrocercus urophasianus ) a sagebrush‐obligate that has population over last several decades, which are attributed variety disturbances including more recent threat oil and gas development. We developed...
First posted March 30, 2021 For additional information, contact: Director,Western Ecological Research CenterU.S. Geological Survey3020 State University Drive EastSacramento, California 95819 Incorporating spatial and temporal scales into greater sage-grouse (Centrocercus urophasianus) population monitoring strategies is challenging rarely implemented. Sage-grouse populations experience fluctuations in abundance that lead to oscillations, making trend estimation difficult. Accounting for...
Sagebrush (Artemisia spp.) ecosystems constitute the largest single North American shrub ecosystem and provide vital ecological, hydrological, biological, agricultural, recreational services. Disturbances have altered reduced this historically, but climate change may ultimately represent greatest future risk. Improved ways to quantify, monitor, predict climate-driven gradual in is its management. We examined annual of Daymet precipitation (daily gridded data) five remote sensing sagebrush...
For more than 100 years, demonstrations have been used by university extension programs and other conservation professionals to increase knowledge, awareness, adoption of agricultural practices technologies. However, there has no systematic, empirical examination the effect on innovations nor practices. We examined relationship between producer attendance at demonstration sites field days four subsequent these using a mail survey (<i>n</i> = 513) in-person interviews 24) with producers in...
A fundamental goal of population ecologists is to identify drivers responsible for temporal variation in abundance. Understanding whether associated with environmental stochasticity or anthropogenic disturbances, which are more amenable management action, crucial yet difficult achieve. Here, we present a hierarchical monitoring framework that models rates change abundance from spatially structured populations and identifies when local declines fall out synchrony trends at larger spatial...
Given the significance of animal dispersal to population dynamics and geographic variability, understanding how is impacted by landscape patterns has major ecological conservation importance. Speaking importance dispersal, use linear mixed models compare genetic differentiation with pairwise resistance derived from surfaces presented new opportunities disentangle menagerie factors behind effective across a given landscape. Here, we combine these approaches novel surface parameterization...
ABSTRACT The scale at which analyses are performed can have an effect on model results and often one does not accurately describe the ecological phenomena of interest (e.g., population trends) for wide‐ranging species: yet, most studies a single, arbitrary scale. To best determine local regional trends greater sage‐grouse ( Centrocercus urophasianus ) in Wyoming, USA, we modeled density‐independent ‐dependent growth across multiple spatial scales relevant to management conservation (Core...

Abstract Multiple environmental stressors impact wildlife populations, but we often know little about their cumulative and combined influences on population outcomes. We generally more past effects than potential future impacts, direct such as changes of habitat footprints indirect, long‐term responses in behavior, distribution, or abundance. Yet, an understanding all these components is needed to plan for landscapes that include human activities wildlife. developed a case study assess how...
Abstract Ecologically relevant references are useful for evaluating ecosystem recovery, but that temporally static may be less when environmental conditions and disturbances spatially heterogeneous. This challenge is particularly acute ecosystems dominated by sagebrush ( Artemisia spp.), where communities require decades to recover from disturbance. We demonstrated application of a dynamic reference approach studying recovery using three cover estimates remote sensing (1985–2018). modelled...
Long-term monitoring of natural resources is imperative for increasing the understanding ecosystem processes, services, and how to manage those ecosystems maintain or improve function. Challenges with using these data may occur because methods changed over time, multiple organizations collect differently, monetary fluctuate, affecting many aspects data. Because species respond changes in habitat conditions predator-prey relationships across different spatial scales that span management...
Abstract Identifying the relevant spatial scale at which species respond to features in a landscape (scale of effect) is pressing research need as managers work reduce biodiversity loss amid variety environmental challenges. Until recently, researchers often evaluated subset potential scales effect inferred from previous studies other locations, based on different biological responses and variables. These approaches, however, can create uncertainty whether were identified, effects variables...

Abstract Population monitoring is integral to the conservation and management of wildlife; yet, analyses population demographic data rarely consider processes occurring across spatial scales, potentially limiting effectiveness adaptive management. Therefore, we developed a method identify hierarchical levels organization (i.e., populations) define multiple specifically intended help guide appropriate actions. This approach can support mobile species with high site fidelity where surveys...
Wildlife populations are increasingly affected by natural and anthropogenic changes that negatively alter biotic abiotic processes at multiple spatiotemporal scales therefore require increased wildlife management conservation efforts. However, boundaries frequently lack biological context mechanisms to assess demographic data across the influencing populations. To address these limitations, we developed a novel approach define biologically relevant subpopulations of hierarchically nested...
Abstract Efforts to restore habitats and conserve wildlife species face many challenges that are exacerbated by limited funding resources. Habitat restoration actions often conducted across a range of habitat conditions, with information available predict potential outcomes among local sites identify those may lead the greatest returns on investment. Using Gunnison sage-grouse ( Centrocercus minimus ) as case study, we leveraged existing resource selection function models areas high...
Widespread ecological degradation has prompted calls for massive global investments in restoration, yet limited resources necessitate efficient application of restoration efforts. In western North America, altered fire regimes are increasing the scale needed to preserve sagebrush (Artemisia species) biome but prioritizing and implementing effective is complicated by vast heterogeneous landscape, which includes gradients climate, disturbance, species composition. To develop spatially explicit...
