Long-distance relationships for endangered corals
Flash-frozen sperm collected from corals in Florida and Puerto Rico was used to fertilize coral eggs from hundreds of miles away in Curaçao. The technique could be used as a conservation tool by introducing genetic variation into endangered corals and potentially accelerating their adaptation to climate change.

Penn State biologist and colleagues receive $4M to identify heat-tolerant corals
An international team that includes Penn State biologist Iliana Baums has been awarded a $4 million grant from the Paul G. Allen Family Foundation to identify corals that are naturally resilient to climate change. This is one of four newly funded projects supported by the foundation that are focused on the conservation and restoration of coral reefs in the context of the climate crisis.

Reef-building corals and microscopic algae within their cells evolve together
The microscopic algae that live inside and provide nutrients to their reef-building coral hosts may be evolving in tandem with the corals they inhabit, so each partner is fine-tuned to meet one another’s needs. A new study by Penn State biologists reveals that genetic differences within a species of these microalgal symbionts correspond to the coral species they inhabit, a discovery that could have implications for the conservation of these endangered corals.

Corals are first animals seen to pass on mutations acquired as adults
Corals have an evolutionary superpower. Adult corals can pass on mutations they have acquired during their lives to their offspring, overturning a long-standing belief that no animals can hand down such mutations – although most can’t.

New tool for identifying endangered corals could aid conservation efforts
Coral conservation efforts could get a boost from a newly developed genotyping “chip” — the first of its kind for corals. The chip allows researchers to genetically identify corals and the symbiotic algae that live within the coral’s cells, a vital step for establishing and maintaining genetic diversity in reef restoration efforts.
