Abstract (from http://www.sciencedirect.com/science/article/pii/S1873965215000110): The goal of this study was to assess the importance of the 2007 sea ice retreat for hydrologic conditions on the Alaskan North Slope, and how this may have influenced the outbreak of tundra fires in this region. This study concentrates on two years, 2007 and 1996, with different arctic sea ice conditions and tundra fire activity. The year of 2007 is characterized by a low summer sea ice extent (second lowest) and high tundra fire activity, while 1996 had high sea ice extent, and few tundra fires. Atmospheric lateral boundary forcing from the NCEP/NCAR Reanalysis drove the Weather Research and Forecast (WRF) model, along with varying...
Abstract (from http://www.bioone.org/doi/abs/10.2112/JCOASTRES-D-13-00202.1): Traditional long-term (decadal) and large-scale (hundreds of kilometers) shoreline change modeling techniques, known as single transect, or ST, often overfit the data because they calculate shoreline statistics at closely spaced intervals along the shore. To reduce overfitting, recent work has used spatial basis functions such as polynomials, B splines, and principal components. Here, we explore an alternative to such basis functions by using regularization to reduce the dimension of the ST model space. In our regularized-ST method, traditional ST is an end member of a continuous spectrum of models. We use an evidence information criterion...

As a low-lying coastal nation, the Republic of the Marshall Islands is at the forefront of exposure to climate change impacts. The Republic of the Marshall Islands has a strong dependence on natural resources and biodiversity not only for food and income but also for culture and livelihood. However, these resources are threatened by rising sea levels and associated coastal hazards (storm surges, saltwater intrusion, erosion, etc.). High-quality data for atoll ‘ridge to reef’ (land and ocean) areas are needed to provide remote communities with the tools and strategies to make adaptation efforts before disasters occur. Although the Republic of the Marshall Islands’ National Strategic Plans recognize the need to...

Throughout Alaska, land managers and rural communities are faced with developing climate adaptation strategies to prepare for changes in landscapes, ecosystems and terrestrial habitats and their associated resources and services. One of the greatest challenges for land use managers and stakeholders in Alaska is the discovery and accessibility of relevant scientific information and data. The effective dissemination and communication of science relies on improving access for stakeholders to discover research, management plans, and data within their geographic area of interest. To respond to this need, the Northwest Boreal Landscape Conservation Cooperative (NWBLCC) has launched the Northwest Boreal Science and Management...
This project snapshot provides a brief overview of the project "Hawaiian Seascapes and Their Management Implications".
A cocktail of land-based sources of pollution threatens coral reef ecosystems, and addressing these has become a key management and policy challenge in the State of Hawaii, other US territories, and globally. In West Maui, Hawai'i, nearly one quarter of all living corals were lost between 1995 and 2008. Onsite disposal systems (OSDS) for sewage leak contaminants into drinking water sources and nearshore waters. In recognition of this risk, the Hawaii State Department of Health (DOH) is prioritizing areas for cesspool upgrades. Independently, we applied a decision analysis process to identify priority areas to address sewage pollution from OSDS in West Maui, with the objective of reducing nearshore coral reef exposure...

Grasslands in the northern Great Plains are important ecosystems that support local economies, tribal communities, livestock grazing, diverse plant and animal communities, and large-scale migrations of big game ungulates, grassland birds, and waterfowl. Climate change and variability impact how people and animals live on and interact with grasslands, and can bring more frequent droughts, fires, or new plant species that make managing these landscapes challenging. Understanding how climate change and variability will impact grassland ecosystems and their management in the 21st century first requires a synthesis of what is known across all of these scales and a gap analysis to identify key areas of focus for future...

Sport fisheries of lakes are embedded in complex system of ecological and social interactions. The multiple drivers that affect lake sport fisheries, along with the complex interactions within lakes, make it difficult to forecast changes in sport fisheries and plan adaptive responses to build resilience of these important resources. Resilience involves managing with an eye toward critical thresholds for behavior of ecosystems. Project researchers are working to develop quantitative tools for assessment of thresholds in sport fisheries that can be used by management agencies to evaluate potential impacts of climate change mediated through species and habitat interactions. Several outputs of the project will be adaptable...

Modeling interactions between human and ecological systems is needed to identify pathways to meet multiple United Nations Sustainable Development Goals. Particularly important is the relationship between biodiversity, ecological processes, and ecosystem services. However, current models tend to ignore impacts of biodiversity on ecological processes. Existing models capture impacts of socio-economic activities on biodiversity or ecosystem services, but critically, links between biodiversity and ecosystem services are only weakly incorporated in most projections and hence in policy design. Knowledge of these relationships has improved, but is scattered across the literature, as are models addressing each component....

For the past few years, “king tides,” or the highest tides of the year, have been occurring more frequently and significantly affecting coastal environments across Hawaiʻi. Now, disappearing beaches and waves crashing over roadways are seemingly the “new normal.” In response, the state of Hawaiʻi is implementing adaptation strategies to combat tidal flooding in coastal areas. While flood management strategies are being implemented in urban areas, less is known about how tidal flooding, and associated inundation into surface and groundwater, might influence watershed dynamics and the native animals that depend on estuarine environments where freshwater meets the sea. Efforts for biocultural restoration of ecosystem...
The Department of the Interior Climate Science Centers (CSCs) and their managing organization, the National Climate Change and Wildlife Science Center at the U.S. Geological Survey, have chosen the emerging climate science field of Ecological Drought as a research focus area. This workshop is part of a series of meetings at each of the nation’s eight CSCs aimed at collating our existing knowledge of the ecological impacts, resistance, and recovery from drought. The eight CSCs provide a fantastic opportunity to compare the ecological effects of drought, related research activities, and management options at different regions, spatial scales, and biomes.
The aim of this project is to facilitate expansion of current data management protocols to accommodate social science data for the USGS National Climate Change and Wildlife Science Center (NCCWSC) and its regional Climate Science Centers (CSCs). To address this expansion, we (1) identified the best practices and approaches from practitioners/experts through interviews with current curators of social science data, (2) explored the approaches of existing tools and services to determine if they are capable of meeting the needs of the NCCWSC, and (3) conducted a survey of the specific user community, with a focus on social science researchers funded by the NCCWSC and managers of the data within the program. The dataset...
The Northern Gulf of Mexico Sentinel Site Cooperative and the Southeast Climate Science Center developed a new resource - Keeping Pace: A short guide to navigating sea-level rise models! This quick four pager covers the importance of model selection, helpful concepts, model categories, and an example of how to utilize these models to address coastal issues. This resource was largely informed by the Sea-Level Rise Modeling Handbook: Resource Guide for Coastal Land Managers, Engineers, and Scientists, which resulted from a Southeast CSC funded project.

Publicly accessible open spaces provide valuable opportunities for people to exercise, play, socialize, and build community. People are more likely to use public open spaces that are close (ideally within walking distance) to their homes. To assess the spatial distribution of access to open space for recreation in the southeastern United States, we constructed an index of open space access based on the size of the largest publicly accessible open space within 10 miles of each point on the landscape, using three distance categories to represent whether people can reach the open spaces by walking (within 0.5 mile), via a short drive (within 3 miles), or via a longer drive (within 10 miles). Using the open space access...

Wild insect pollination has significant positive effects on pollinator-dependent crop production. To assess the spatial distribution of demand for wild insect pollination, we mapped pollinator-dependent crops based on the 2011Cropland Data Layer.
Abstract (from ScienceDirect ) Ecosystem accounts, as formalized by the System of Environmental-Economic Accounting Experimental Ecosystem Accounts (SEEA EEA), have been compiled in a number of countries, yet there have been few attempts to develop them for the U.S. We explore the potential for U.S. ecosystem accounting by compiling ecosystem extent, condition, and ecosystem services supply and use accounts for a 10-state region in the Southeast. The pilot accounts address air quality, water quality, biodiversity, carbon storage, recreation, and pollination for selected years from 2001 to 2015. Results illustrate how information from ecosystem accounts can contribute to policy and decision making. Using an example...
