The history of life on Earth has been punctuated by several mass extinctions, the greatest of these being the Permian-Triassic extinction event, also known as the “Great Dying,” which occurred 252 million years ago.

Aquaculture, or the farming of aquatic plants and animals, contributes to biodiversity and habitat loss in freshwater and marine ecosystems globally, but when used wisely, it can also be part of the solution, new research shows.

Blue foods — those that come from the ocean or freshwater environments — have tremendous potential to help address several global challenges.

Missouri is home to an array of natural resources, with forests among the state’s most valuable ecosystems. 

When the Covid-19 pandemic hit in 2020 with associated travel restrictions, Matthew Long thought his students could shift their overseas research projects to instead study the seagrass meadow ecosystem in Waquoit Bay.

Can a single bottle of ocean water contain enough scraps of genetic material for researchers to identify virtually all of the fish, plankton, molluscs, marine mammals and other organisms from that location?

Some corals in the eastern Pacific are adapting to a warmer world by hosting more heat-tolerant algae, according to new research that offers hope for the world’s embattled reefs.

The tropical oceans are home to the most diverse plankton populations on Earth, where they form the base of marine food chains. 

Seabed mining could soon begin in the deep ocean – but the potential impact on animals including whales is unknown, researchers have warned.
