Cycloprodigiosin: A multispecies settlement cue for scleractinian coral larvae.

The survival of coral reefs depends on the rejuvenation of coral populations with the potential to adapt and survive a changing climate. Assisted sexual reproduction has become an important tool in reef management. One bottleneck is the efficient and manageable induction of coral larval settlement.

Ocean acidification alters fish-jellyfish symbiosis.

Symbiotic relationships are common in nature, and are important for individual fitness and sustaining species populations. Global change is rapidly altering environmental conditions, but, with the exception of coral-microalgae interactions, we know little of how this will affect symbiotic relationships. We here test how the effects of ocean acidification, from rising anthropogenic CO2 emissions, may alter symbiotic interactions between juvenile fish and their jellyfish hosts.
