Algae

A Completely New Kind of Symbiotic Relationship

We’ve seen animals and plants, plants and fungi, animals and bacteria, all with symbiotic relationships that benefit both species. Some combinations even take that relationship to the cellular level. But now scientists have identified algae living in salamander cells through the life of the animal, which is the first time a photosynthetic plant has been found in the cells of a vertebrate.

As a collaborative research team from the American Museum of Natural History and Gettysburg College revealed, the green alga Oophila amblystomatis makes its home inside of cells located across…

The Great Barrier Reef is experiencing a major coral bleaching event right now

Corals along large swaths of the Great Barrier Reef have lost their symbiotic algae, removing their vibrant colors and primary food supply, new observations show.

A severe coral bleaching event spurred by high ocean temperatures has struck the Great Barrier Reef for an unprecedented second time in 12 months, reveal aerial surveys released April 10 by scientists at James Cook University in Townsville, Australia. While last year the northern third of the reef was hardest hit, this time around the reef’s midsection experienced the worst bleaching. The two bleaching events together span around 1,500 kilometers of the 2,300-kilometer-long reef.

“It takes at least a decade for a full recovery of even…
