Increasing wildfire activity in much of North America is having severe impacts on society and ecosystems. Climate change is a key driver of changing fire regimes across North America, with varying expressions across the continent. Modern fire records, while useful, are too short to fully characterize the complex patterns and non-linear dynamics of fire-climate relationships that are required to understand future fire activity in a warmer climate. Tree-ring fire scars offer a unique perspective because they are spatially precise, direct evidence of fires with annual to sub-annual resolution spanning centuries. For the first time, we have compiled tree-ring fire scar records across North America (n = 2,593 sites,...
In Louisiana, the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) identifies, prepares, and funds coastal wetland restoration projects. In the Evaluation Report to Congress to be submitted in 2024, geospatially driven visualizations are required to provide conceptual understanding of funded project sizes and locations as they pertain to the geographical region in designated basins, as well as identify key project information and expenditures.

Marine birds are wide-ranging apex predators and good indicators of changes in marine ecosystems since they spend most of their lives offshore. Pro-active marine bird monitoring at sea contributes to long-term trends and allows researchers to better anticipate potential future responses of upper trophic levels to changes in the marine ecosystem. The principal goal of this project is to conduct marine bird surveys in the offshore waters of Alaska (Gulf of Alaska, Bering Sea, Chukchi Sea, Beaufort Sea, and the Arctic Ocean). The surveys provide current temporal and spatial data on marine birds to advance regional knowledge for informed marine planning decisions to enable effective long-term management and sustainable...

This database contains literature citations and associated abstracts pertaining to the ecology and hydrology of terminal lakes in the Great Basin region of the western United States. This is not meant to be an exhaustive list, nor did we perform a systematic meta-analysis; rather, literature records were included based on topical relevance.
