Biography
I am an ecologist focused on wildlife and ecosystems in working landscapes. I work to meet science needs of natural resource managers and agencies by studying effects of management on avian population trends, demographics, and distribution, as well as restoration and ecosystem recovery. I also am interested in using simulation and hierarchical models to understand observation processes.

Science and Products
Energy Development and Changing Land Uses
Applied research and integrated regional assessments emphasize spatially explicit analyses of ecosystem components affected by energy development and land-use change in the western United States. Topics include sagebrush-steppe ecology; sagebrush habitat assessments; the effets of human activities (including energy development, transportation, and recreation) on habitats and wildlife behavior...
Conservation of Sagebrush Ecosystems and Wildlife
Sagebrush ecosystems are diverse habitats found throughout western North America that support a variety of flora and fauna. Home to unique wildlife such as Sage-grouse, Sage Thrashers, Brewer's Sparrows, Ferruginous Hawks, and pygmy rabbits, these ecosystems have undergone intense changes since the time when millions of bison roamed the plains. European settlement and intense agricultural...
Range-wide greater sage-grouse hierarchical monitoring framework—Implications for defining population boundaries, trend estimation, and a targeted annual warning system
Incorporating spatial and temporal scales into greater sage-grouse (Centrocercus urophasianus) population monitoring strategies is challenging and rarely implemented. Sage-grouse populations experience fluctuations in abundance that lead to temporal oscillations, making trend estimation difficult. Accounting for stochasticity is critical to...

Prioritizing landscapes for grassland bird conservation with hierarchical community models
ContextGiven widespread population declines of birds breeding in North American grasslands, management that sustains wildlife while supporting rancher livelihoods is needed. However, management effects vary across landscapes, and identifying areas with the greatest potential bird response to conservation is a pressing research need.ObjectivesWe...
Monroe, Adrian Pierre-Frederic; Edmunds, David R.; Aldridge, Cameron L.; Holloran, Matthew J; Assal, Timothy J; Holloran, Alison G The importance of simulation assumptions when evaluating detectability in population models
Population monitoring is important for investigating a variety of ecological questions, and N-mixture models are increasingly used to model population size (N) and trends (lambda) while estimating detectability (p) from repeated counts within primary periods (when populations are closed to changes). Extending these models to dynamic processes with...
Monroe, Adrian P.; Wann, Gregory T.; Aldridge, Cameron L.; Coates, Peter S. Assessing lek attendance of male greater sage‐grouse using fine‐resolution GPS data: Implications for population monitoring of lek mating grouse
Counts of males displaying on breeding grounds are the primary management tool used to assess population trends in lekking grouse species. Despite the importance of male lek attendance (i.e., proportion of males on leks available for detection) influencing lek counts, patterns of within season and between season variability in attendance rates are...

U.S. Geological Survey science for the Wyoming Landscape Conservation Initiative—2017 annual report
The Wyoming Landscape Conservation Initiative (WLCI) was established in 2008 to address the scientific and conservation questions associated with land use changes because of energy development and other factors in southwest Wyoming. Over the past decade, partners from U.S. Geological Survey (USGS), State and Federal land management agencies,...

Edmunds, David R.; Aldridge, Cameron L.; O'Donnell, Michael; Monroe, Adrian P. Nest survival modelling using a multi-species approach in forests managed for timber and biofuel feedstock
Switchgrass (Panicum virgatum) intercropping is a novel forest management practice for biomass production intended to generate cellulosic feedstocks within intensively managed loblolly pine‐dominated landscapes. These pine plantations are important for early‐successional bird species, as short rotation times continually maintain early‐successional...
Loman, Zachary G.; Monroe, Adrian P.; Riffell, Samuel K.; Miller, Darren A.; Vilella, Francisco; Wheat, Bradley R.; Rush, Scott A.; Martin, James A. Greater sage-grouse population trends across Wyoming
The scale at which analyses are performed can have an effect on model results and often one scale does not accurately describe the ecological phenomena of interest (e.g., population trends) for wide-ranging species: yet, most ecological studies are performed at a single, arbitrary scale. To best determine local and regional trends for greater sage...
Edmunds, David R.; Aldridge, Cameron L.; O'Donnell, Michael; Monroe, Adrian P. Patterns in Greater Sage-grouse population dynamics correspond with public grazing records at broad scales
Human land use, such as livestock grazing, can have profound yet varied effects on wildlife interacting within common ecosystems, yet our understanding of land-use effects is often generalized from short-term, local studies that may not correspond with trends at broader scales. Here we used public land records to characterize livestock grazing...
Monroe, Adrian P.; Aldridge, Cameron L.; Assal, Timothy J.; Veblen, Kari E.; Pyke, David A.; Casazza, Michael L. The integrated rangeland fire management strategy actionable science plan
The Integrated Rangeland Fire Management Strategy (hereafter Strategy, DOI 2015) outlined the need for coordinated, science-based adaptive management to achieve long-term protection, conservation, and restoration of the sagebrush (Artemisia spp.) ecosystem. A key component of this management approach is the identification of knowledge gaps that...

Effects of lek count protocols on greater sage-grouse population trend estimates
Annual counts of males displaying at lek sites are an important tool for monitoring greater sage-grouse populations (Centrocercus urophasianus), but seasonal and diurnal variation in lek attendance may increase variance and bias of trend analyses. Recommendations for protocols to reduce observation error have called for restricting lek counts to...
Monroe, Adrian P.; Edmunds, David R.; Aldridge, Cameron L. The ovenbird (Seiurus aurocapilla) as a model for testing food-value theory
Food-value theory states that territorial animals space themselves such that each territory contains adequate food for rearing young. The ovenbird (Seiurus aurocapilla) is often cited as a species for which this hypothesis is supported because ovenbird territory size is inversely related to ground-invertebrate abundance within territories. However...
