New USGS Map Identifies Non-Native Aquatic Species Potentially Spread by Hurricane Isaias Floodwaters
The USGS has released the initial Flood and Storm Tracker (FaST) map for Hurricane Isaias, the Category 1 storm that swept up the mid-Atlantic coast last week.
Seafloor Methane Seeps at the Edge of Hydrate Stability
In June 2019, USGS scientists led a 22-day deep-sea research expedition aboard the R/V Falkor to examine methane seep dynamics and processes along the Cascadia Margin offshore of Washington and Oregon.

A global biophysical typology of mangroves and its relevance for ecosystem structure and deforestation
Mangrove forests provide many ecosystem services but are among the world’s most threatened ecosystems. Mangroves vary substantially according to their geomorphic and sedimentary setting; while several conceptual frameworks describe these settings, their spatial distribution has not been quantified. Here, we present a new global mangrove...

Species are a fundamental unit of biology, and defining accurate species boundaries is integral to effective conservation and management of imperiled taxa. Freshwater mussels (Bivalvia: Unionidae) are among the most imperiled groups of organisms in North America, yet species boundaries remain uncertain for many taxa. The False Spike, ...
Smith, Chase H.; Johnson, Nathan; Havlik, Kaitlyn; Doyle, Robert D.; Randklev, Charles R. Genetic diversity targets and indicators in the CBD post-2020 Global Biodiversity Framework must be improved
The 196 parties to the Convention on Biological Diversity (CBD) will soon agree to a post-2020 global framework for conserving the three elements of biodiversity (genetic, species, and ecosystem diversity) while ensuring sustainable development and benefit sharing. As the most significant global conservation policy mechanism, the new CBD framework...
