Corals

Hibernating Corals and the Microbiomes That Sustain Them

As winter approaches, many species of animals — from bears and squirrels to parasitic wasps and a few lucky humans — hunker down for some needed rest. The northern star coral (Astrangia poculata) also enters a hibernating state of dormancy, or quiescence, during this time. But what happens to its microbiome while it’s sleeping?

Corals Saving Corals

Under the right living arrangement, disease-resistant corals can help “rescue” corals that are more vulnerable to disease, found a study from the University of California, Davis, that monitored a disease outbreak at a coral nursery in Little Cayman, Cayman Islands.

Coral reefs are foundational and iconic ecosystems that have long captivated many with their vibrant colors, interesting ecology, and ecosystem productivity. However, these beautiful reefs are facing their biggest challenge yet: climate change. How can immobile marine organisms, such as corals, survive and thrive in waters that are steadily warming? Leslie Guerrero, a PhD student in the Bay Lab at UC Davis, is working tirelessly to answer these questions.
