Predicted population cores (25%, 50% and 75%) of breeding thick-billed longspur (Rhynchophanes mccownii) based on a range-wide random forest distribution model. We summed the probability of occurrence across all pixels in the study region to generate an index of total population. We placed each grid cell prediction in the context of the study area by dividing the individual pixel probability by the total index. Starting with the highest-value pixels, we cumulatively summed the probabilities until a given threshold was met. We set 25, 50 and 75% thresholds to delineate cores as the smallest possible areas containing the highest concentrations of predicted birds.
Adaptive divergence is expected among sockeye salmon (Oncorhychus nerka) populations because they spawn in diverse habitats and experience spatially and temporally restricted gene flow. Genetic bottleneck effects are also expected among sockeye salmon populations because they are a highly structured species with excellent colonizing abilities. To test if phenotypic divergence among sockeye salmon populations is due to local adaptation or genetic drift, I compared neutral genetic and heritable phenotypic variation in spawning populations of sockeye salmon throughout the Lake Clark area of Alaska. I assessed nuclear (microsatellites and allozymes) and mitochondrial DNA variation of 15 sockeye salmon populations. Reduced...
Alluvial floodplains are unique geomorphic features of lotic systems that are characterized by a shifting morphology in three spatial dimensions. This spatial and temporal heterogeneity is thought to explain why these aquatic-terrestrial ecotones are the most species-rich habitats on the terrestrial portions of earth. Many factors and processes influencing these high levels of species richness remain unstudied, however. Regional factors, such as regional species pools, and local factors, such as groundwater-surface water exchange have received little consideration as factors controlling local species richness on floodplains. Additionally, the conservation of these habitats and the biodiversity they support remains...

Montane Conifer Connectivity of areas of high elevation and high human footprint in the North Pacific Landscape Conservation Cooperative study area. This application provides Montane Conifer Connectivity for 2000 and 2080 (A1B).The three primary geospatial layers used in this analysis were a digital elevation model (DEM), a vegetation layer, and a human footprint layer. Due to the geographic extent of the North Pacific Landscape Conservation Cooperative, digital elevation models from different sources had to be used to create one seamless DEM. The digital elevation models were obtained from the Shuttle Radar Topography Mission (SRTM), the United States Geologic Survey, and the Government of the Yukon Territory....

Overview Land and resource managers in the North Pacific Landscape Conservation Cooperative (NPLCC) currently lack conservation planning tools that can directly feed into the planning, design, delivery, and monitoring of ecosystems across all levels of biodiversity from genes to ecosystems. The North Pacific Forest Landscape Corridor and Connectivity Project utilized a landscape connectivity simulator (UNICOR) and a genetic simulation program (CDPOP) to model the functional (dispersal and genetic) connectivity in the North Pacific Landscape. The outputs from these programs indicated areas with high potential for landscape and genetic isolation and low probability of dispersal and colonization. In addition, this...

FY2013This project retrieves four years of data from over 200 temperature sensors nested within 28 sites across ~40 million hectares of the hydrographic Great Basin. The sensors span all major aspects and up to 700 m of elevation within sites, and occur in numerous management jurisdictions in 18 mountain ranges plus other areas not in ranges. This project: Quantifies the variability of climate at micro-, meso-, and macroscales across the Basin, and across diel, seasonal, and interannual periods. Informs management and conservation efforts, in terms of helping calibrate and refine the climatic stage upon which all biological actors and efforts hinge (Beier and Brost 2010). Feeds into other bioclimatic and wildlife...

Greater sage-grouse genetic connectivity is essential to the species persistence across the Great Northern landscape; without such connectivity the greater sage-grouse may suffer the same fate as many other related species of grouse, which disappeared from the middle and eastern portion of the United States due to loss of habitat coupled with inbreeding depression. To prevent isolation in the face of energy development and other landscape changes it is essential that we evaluate both fine-scale connectivity and assign relative importance to different leks (breeding populations) on the landscape. This massive task cannot be accomplished with existing tools and maps; fortunately, advanced molecular genomic analyses...

Grassland birds have declined more rapidly than any other group of land birds in North America in the last 50 years, with populations of Spragues Pipit, Chestnut-collared and Thick-billed Longspur, and Bairds Sparrow having declined 65-94% during this period. Developing strategic conservation plans for grassland birds requires an understanding of their individual population ecology, along with their community dynamics amongst species. Few studies have focused on understanding how adult density during the breeding season relates to nesting performance (e.g., nest density and nest success) and how abiotic and biotic factors influence these individual demographics. This proposed work complements concurrent studies...

Genetic variation has been correlated with individual fitness and population growth rates. Population genetic theory predicts that the amount of genetic variation in a neutral region of a genome is primarily a function of effective population size. In theory, populations on the periphery of a species geographic range have small effective population sizes and fewer connections to other populations, leading to a reduction in genetic variation. However, the influence of location on the landscape on genetic variation has largely been ignored. I combine principles of landscape ecology and population genetics to determine the effect of location on the landscape on genetic variation in two threatened, mid-sized carnivores;...

More than 620,000 miles of rivers are affected by over 79,000 dams in the United States. The dams are a valuable asset, however dams block fish passage, and disrupt the physical and biological systems, and alter hyporheic exchange. In efforts to remediate rivers impacted by dams, dam removal is being proposed. Changes in the location and timing of groundwater and river water exchanges in post dam remediated river systems are typically not identified. The goal of this study was to examine the factors controlling surface water and groundwater exchange rates and locations in river systems during dam removal. Specific tasks included establishing a river elevation and groundwater elevation monitoring network, defining...

Measurements of bedload transport in combination with suspended sediment and discharge data collected by the USGS illustrate the rates, magnitudes and processes by which reservoir sediment evacuated the Milltown Reservoir after the 2008 removal of Milltown Dam from just downstream of the confluence of the Blackfoot and Clark Fork Rivers, Montana. Mobilized sediments transported as a series of distinct waves and the speed at which the waves moved downstream was dependent upon the grain size of the sediment. Sand and smaller sized particles were transported out of the reservoir rapidly both as bedload and in suspension with different thresholds for incipient motion between the confined Blackfoot and unconfined alluvial...

This project will support the design and development of a large-scale aquatics monitoring program across 1.5 million acres of the Crown of the Continent, as part of a 10-year, landscape-level restoration project established and funded by the U.S. Forest Service in 2010. The Forest Service has directed each of ten Cooperative Forest Landscape Restoration Program projects to develop and implement a large-scale monitoring program to inventory current resource conditions and facilitate the short- and long-term evaluation of the effectiveness of restoration projects to inform future management strategies and actions: the work proposed here would address significant challenges associated with maintaining or improving...

Livestock grazing practices are managed by private landowners and federal and state agencies across the western U.S. Increasingly, grazing strategies by these entities are incorporating conservation objectives and developing goals that include livestock production that is compatible with wildlife conservation objectives. This project evaluates the impact of conservation-oriented, rest-rotation livestock grazing and climate changes on migratory bird species associated with sagebrush habitat to better inform grazing management practices. Rest-rotation grazing management is likely to enhance important components of sagebrush, shrubland, and grassland habitat for a wide range of species, but little work has been done...

In recent decades, climate change has been invoked in the apparent collapse of some of the best-known examples of cyclic and synchronous population dynamics among boreal species. Simultaneously, some studies have predicted that as species' ranges shift poleward and southern habitats fragment in response to climate change, we will lose the southern glacial refugial populations that have historically harbored species' highest genetic diversity and uniqueness. I investigated how climate change and habitat fragmentation may impact genetic and population dynamic processes for the snowshoe hare ( Lepus americanus ), a species historically recognized as a key driver of North American boreal community dynamics. I collected...
This region-wide coordinated bird monitoring program, supported by state, federal, tribal, nongovernmental organizations, and two statewide bird conservation partnerships, is designed to provide spatially-referenced baseline data for science-based biological planning and conservation design for the Great Northern LCC and its partners that is directly comparable with other landscapes and BCRs. We are requesting a third year of funding to continue sampling in BCR10 Montana and Idaho to enhance our ability to make robust inference to bird populations on grassland, shrublands, and riparian systems. These data currently are being used by project partners to develop spatially-explicit models that will allow assessment...
