A metapopulation strategy to support long term conservation of genetic diversity in Department of the Interior bison A metapopulation strategy to support long term conservation of genetic diversity in Department of the Interior bison

Once numbering in the tens of millions, plains bison (Bison bison bison) were nearly driven to extinction with only a few hundred individuals remaining by the late 19th century. Plains bison have since recovered to approximately 20,000 animals managed in conservation herds throughout North America, yet substantial challenges to their recovery remain. The Department of the Interior (DOI)...

Climate vulnerability assessment of Oregon hatchery programs Climate vulnerability assessment of Oregon hatchery programs

The goal of this project was to assess the vulnerability to climate change impacts for a sample set of hatchery programs representing different geographic areas and primary anadromous species raised in state-managed Oregon hatcheries (Summary Figure 1). Freshwater and marine ecosystem processes can significantly influence salmon and steelhead survival, and understanding how these factors...

Site-specific, extended ShakeMaps for earthquake engineering applications Site-specific, extended ShakeMaps for earthquake engineering applications

The U.S. Geological Survey (USGS) routinely produces ShakeMaps of shaking intensity across the globe. Due to practical constraints, the number of response spectral periods was limited to three standard periods (0.3, 1.0, and 3.0 sec). We have recently developed the tools that are necessary to expand this functionality to include 22 periods (matching the current U.S. National Seismic...

Restoration monitoring metric framework: Integrating innovative remote-sensing technologies: Comparisons between field and remotely sensed vegetation surveys of restored forested and grassland sites in Ohio Restoration monitoring metric framework: Integrating innovative remote-sensing technologies: Comparisons between field and remotely sensed vegetation surveys of restored forested and grassland sites in Ohio

Restoration monitoring is generally perceived as costly and time-consuming, yet the concept of universal restoration monitoring metrics is trending for evaluation of restoration performance across spatial scales, project boundaries, and jurisdictions. Natural Resource Damage Assessment and Restoration (NRDAR) practitioners seek to restore natural resources injured by oil spills or...

Global Food Security Support Analysis Data (GFSAD) using remote sensing in support of food and water security in the 21st century Global Food Security Support Analysis Data (GFSAD) using remote sensing in support of food and water security in the 21st century

The overarching goal of this chapter is to provide a comprehensive overview of the state-of-art of global cropland mapping procedures using remote sensing as characterized and envisioned by the “Global Food Security Support Analysis Data @ 30 m (GFSAD30)” project working group team. First, the chapter will provide an overview of existing cropland maps and their characteristics along with

Seasonal and spatial patterns in sediment transport in an erosional marsh system Seasonal and spatial patterns in sediment transport in an erosional marsh system

Salt marshes provide expansive ecosystem services to coastal regions, including serving as bird and fish habitat, providing flood protection, and sequestering carbon and toxins (Barbier et al. 2011). While marshes are naturally dynamic, they are undergoing net loss in the 21st century largely due to lateral erosion (Camp- bell et al. 2022). In regions where marsh migration is constrained...
