To improve climate models, an international team turns to archaeological data
The project, called LandCover6k, offers a new classification system that the researchers hope will improve predictions about the planet’s future and fill in gaps about its past.
Declines in shellfish species on rocky seashores match climate-driven changes
Mussels, barnacles, and snails are declining in the Gulf of Maine, according to a new paper by biologists Peter Petraitis of the School of Arts & Sciences and Steve Dudgeon of California State University, Northridge. Their 20-year dataset reveals that the populations’ steady dwindling matches up with the effects of climate change on the region.

Fruit flies’ microbiomes shape their evolution
In just five generations, an altered microbiome can lead to genome-wide evolution in fruit flies, according to new research led by Paul Schmidt and postdoc Seth Rudman of the School of Arts and Sciences.
Inferno in the rainforest
Satellite images have detected more than 100,000 points of fire in the Amazon this year. Scientists Reto Gieré and Alain Plante illuminate some less obvious impacts of the fires, including health threats and climate impacts.
Making insights into ancient marine ecosystems with 3D-printed shells
If you’re a snail hoping to survive an encounter with a hungry fish, it helps to have a strong shell. Paleoecology doctoral student Erynn Johnson is using 3D printing to understand how predator-prey interactions may have played out hundreds of millions of years ago.
