Prey-size plastics are invading larval fish nurseries
(Arizona State University, Center for Global Discovery and Conservation Science) A new study by researchers at Arizona State University’s Center for Global Discovery and Conservation Science (GDCS) and NOAA’s Pacific Islands Fisheries Science Center has revealed that larval fish species from various ocean habitats are now being threatened by plastic pollution that infects their nursery habitats—at levels on average, eight times higher than those recently found in the Great Pacific Garbage Patch. The study was published in the journal Proceedings of the National Academy of Sciences.

Classic energy theory fails to explain coral distribution across depth
Coral species richness at different depths is unrelated to energy availability, according to a new study analyzing diversity across an Australasian reef.
Red algae thrive despite ancestor’s massive loss of genes
You’d think that losing 25 percent of your genes would be a big problem for survival. But not for red algae, including the seaweed used to wrap sushi. An ancestor of red algae lost about a quarter of its genes roughly one billion years ago, but the algae still became dominant in near-shore coastal areas around the world.
Corals from the twilight zone: Who eats what on a deep Red Sea reef
(Bar-Ilan University) Using remote operated underwater vehicles a group of scientists is collaborating on a new project to study coral reefs found below scuba diving depth. Little is known about these deep-water reef systems, but they may be very important for the survival of coral reefs under global climate change, and accessing these places using technical diving and ROVs is a crucial part of the current mission.
Strong winter dust storms may have caused the collapse of the Akkadian Empire
(Hokkaido University) Fossil coral records provide new evidence that frequent winter shamals, or dust storms, and a prolonged cold winter season contributed to the collapse of the ancient Akkadian Empire in Mesopotamia.
