More than half of Hudson River tidal marshes were created accidentally by humans

In a new study of tidal marsh resilience to sea level rise, geologist and first author Brian Yellen at the University of Massachusetts Amherst and colleagues observed that Hudson River Estuary marshes are growing upward at a rate two to three times faster than sea level rise, "suggesting that they should be resilient to accelerated sea level rise in the future," he says.

Identifying where to reforest after wildfire

In the aftermath of megafires that devastated forests of the western United States, attention turns to whether forests will regenerate on their own or not. Forest managers can now look to a newly enhanced, predictive mapping tool to learn where forests are likely to regenerate on their own and where replanting efforts may be beneficial.

Researchers take a closer look at the genomes of microbial communities in the human mouth

Bacteria often show very strong biogeography—some bacteria are abundant in specific locations while absent from others—leading to major questions when applying microbiology to therapeutics or probiotics: how did the bacteria get into the wrong place? How do we add the right bacteria into the right place when the biogeography has gotten 'out of whack'?
