The project objectives are as follows: To map out current and future levels of habitat connectivity in the South Atlantic region, from the standpoint of multiple groups of terrestrial wildlife species; 2. To prioritize key corridors and linkage areas based on their relative importance and centrality within the overall habitat network and their relative influence on the viability of target wildlife populations; 3. To publish data layers representing the outcomes from the first two objectives, in such a way as to significantly improve conservation decision-making across the South Atlantic LCC region

Sea level rise (SLR) and disturbances from increased storm activity are expected to diminish coastal habitats available for sea turtle, seabird, shorebird, and beach mouse nesting by removing habitat as well as inundating nests during critical incubation periods. The goal of our proposed research is to evaluate past nesting patterns of fourteen coastal nesting species and predict future effects of sea level rise on nesting beaches along the South Atlantic Bight. Maps of coastal vulnerability to SLR combined with historical data sets of long-term and spatially extensive nesting habitat will lead to models that enhance our understanding of the complex environmental changes occurring from global climate change and...

Land transformations occurring from energy development and agrarian use have altered the natural connectivity of fish communities inhabiting prairie waterways. The nation’s prairie waterways are obstructed by thousands of barriers that include road culverts, irrigation diversions, and dams. Connectivity is essential for the long term viability of aquatic species. One of the most promising adaptive management strategies for addressing impacts to aquatic systems by climate change and other landscape stressors is increasing connectivity. The purpose of this research is to characterize swimming abilities of three northern plains fish species; the sauger, the longnose dace, and the fathead minnow. The results of the...

Cottonwood forests are in decline becasue of losses from land use conversion and reduced regeneration from river regulation. Projecting lon-term implications of current trends and policies, or alterations of these, will help to identify the importance and scale of restoration activities needed to offset losses. This project developed a landscape dynamic model to project future (eig. 25, 50, 100 year) trends in cottonwood forst area and age distribution for four remnant floodplain reches on the Missouri River, based on recent rates (or alternative scenarios) of land use change, cottonwood recruitment, and succession. For two reaches, these changes are used to project the effects onabundances of selected songbird...

Rapid expansion of cropland threatens grassland ecosystems across western North America and broad-scaleplanning can be a catalyst motivating individuals and agencies to accelerate conservation. Sprague’s Pipit(Anthus spragueii) is an imperiled grassland songbird whose population has been declining rapidly in recent decades.Here, we present a strategic framework for conservation of pipits and their habitat in the northern GreatPlains.We modeled pipit distribution across its million-km2 breeding range in Canada and the U.S.We describefactors shaping distribution, delineate population cores and assess vulnerability to future grassland losses. Pipitsselected landscapes with a high proportion of continuous grassland...

Within the time frame of the longevity of tree species, climate change will change faster than the ability of natural tree migration. Migration lags may result in reduced productivity and reduced diversity in forests under current management and climate change. We evaluated the efficacy of planting climate-suitable tree species (CSP), those tree species with current or historic distributions immediately south of a focal landscape, to maintain or increase aboveground biomass, productivity, and species and functional diversity. We modeled forest change with the LANDIS-II forest simulation model for 100 years (2000–2100) at a 2-ha cell resolution and five-year time steps within two landscapes in the Great Lakes region...

This project applied the results of an on-going climate change vulnerability assessment to the management of two complex landscapes. The vulnerability assessment project team worked with managers, land-owners, and conservation practitioners to explore 1) how downscaled climate datasets, modeled vegetation changes, and information on estimated species sensitivities could be used to develop climate change adaptation strategies, and 2) how model results and datasets could be made more useful for informing the management of species and landscapes. To accomplish these two goals, datasets and model outputs for two landscapes were prepared, 1) the British Columbia Park system, specifically the midcoast region, and 2) the...

Potamodromous migrations, those that occur entirely in fresh waters, are made by a variety of minnows (Family Cyprinidae) in, and between, freshwater habitats around the world. These migrations most commonly are undertaken for purposes of breeding, feeding, or occupying specific habitats or refugia. There is a growing body of evidence that potamodromous migrations are undertaken by a number of cyprinids native to larger streams and rivers of the Great Plains region of central USA. Cross et al. (1985) observed that populations of Arkansas River shiner disappeared from large tributaries to the Arkansas River, in Kansas, as a result of dam construction and water withdrawal. They speculated that populations in these...
This project integrates fire risk models, species distribution models (SDMs) and population models with scenarios of future climate and land cover to project how the effects of climate-induced changes to species distributions and land use change will impact threatened species in fire-prone ecosystems. This project also identifies and prioritizes potential management responses to climate change (e.g. assisted colonization, fire management, land protection, dispersal corridors). Anticipated products include: 1) maps (digital and hard copy) of habitat suitability under current and future climate change, current and future projected urban growth and combinations of climate change and future projected urban growth, under...

This project used species distribution modeling, population genetics, and geospatial analysis of historical vs. modern vertebrate populations to identify climate change refugia and population connectivity across the Sierra Nevada. It is hypothesized that climate change refugia will increase persistence and stability of populations and, as a result, maintain higher genetic diversity. This work helps managers assess the need to include connectivity and refugia in climate change adaptation strategies. Results help Sierra Nevada land managers allocate limited resources, aid future scenario assessment at landscape scales, and develop a performance measure for assessing resilience.

Rates of glacier loss in the northern Pacific coastal temperate rainforest (PCTR) are among the highest on Earth. These changes in glacier volume and extent will affect the flow and chemistry of coastal rivers, as well as the nearshore marine ecosystem of the Gulf of Alaska (GOA). Runoff from glaciers accounts for about half of the land-to-ocean movement of freshwater into the GOA, strongly influencing the freshwater and marine ecosystems along the coast. Runoff from glaciers, for example, significantly impacts the water temperature and clarity of aquatic habitats, which are important conditions for salmon reproduction. Moreover, runoff from glaciers along the GOA is an important factor in the structure of the...

Ongoing and future climate change throughout Alaska has the potential to affect terrestrial ecosystems and the services that they provide to the people of Alaska and the nation. These services include the gathering of food and fiber by Alaskan communities, the importance of ecosystems to recreation, cultural, and spiritual activities of people in Alaska, and the way that land cover and vegetation in ecosystems affect temperature and water flow (runoff, flooding etc.) throughout the state. Assessments of the effects of climate change on these “ecosystem services” have been hindered by a lack of tools (e.g. computer models) capable of forecasting future landscapes in a changing climate while taking into account numerous...

Ongoing climate change has the potential to negatively impact Alaska’s ecosystems and the critical services that they provide. These ecosystem services include supplying food and fiber for Alaskan communities, offering opportunities for recreational, cultural, and spiritual activities, and regulating temperature and water flow (runoff, flooding, etc.). Scientists build models to better understand processes and interactions in the natural environment and to use what we know to predict what will happen in the future, so that we can plan for it. Researchers from multiple institutions and disciplines developed an Integrated Ecosystem Model (IEM) for Alaska and Northwest Canada. The model helps forecast how climate...

The efficiency and effectiveness of aerial photography by the U.S. Fish and Wildlife Service’s Midwest Aviation Program has been improved with upgraded components for the Applanix DSS 439 Camera System, including a 60 millimeter lens and gyro-stabilization mount. Both are installed and in use. The stabilization mount improves image resolution and minimizes asymmetrical pixels. The 60 millimeter lens also improves image resolution for higher quality aerial photographs. This advanced equipment results in more accurate bird counts and stereo interpretation of vegetation maps which will ultimately assist management decisions made in biological programs.

Coral reefs are some of the most biologically rich and economically valuable ecosystems in the world. They provide food, fishing, and recreation opportunities for millions of people, protect coastlines from storms, and shelter thousands of plant and animal species. However, climate change is contributing to the degradation of coral reefs in two significant ways: warming temperature and increasing acidification of ocean waters. Scientists are actively working to gather more specific information about how these factors will impact coral reef ecosystems. The purpose of this study was to identify differences in climate vulnerability among three important reef-building coral species in the Florida Keys. Researchers...
