Coping with Invasive Alien Species and Environmental Stressors: Linking Behavioral Studies with Management for Anuran Amphibians

Climate change and invasive species are two key drivers of biodiversity loss. Knowing how amphibians respond to climate change and invasive species can greatly improve predictions of species' persistence in the face of these factors and can help guide resource managers and conservation biologists in developing strategies to manage for these encroaching disturbances.

SWOT - Surface Water and Ocean Topography

Satellite altimetry associated with the Surface Water and Ocean Topography (SWOT) mission offers a solution for measuring (1) river stage and slope, (2) water surface area including mean channel width and (3) derivatives such as river discharge. The measurements can be used to track changes in these variables and provide an accounting of the Earth's fresh-water bodies from space at the reach...
