Genetics Reveal that Reef Corals and Their Algae Live Together but Evolve Independently (1 of 3) (image) Penn State Share Print E-Mail Caption Shallow reef waters were once dominated by extensive thickets of the Caribbean Elkhorn Coral, Acropora palmata, a species that is now threatened by climate change. Restoration and conservation efforts are underway. New research by a team of Penn State scientists provides unprecedented genetic resolution of the coral host and its algal partner. This information is vital for preserving the genetic diversity of the endangered coral in combination with its algal partner. This impressive stand, photographed in Curacao, provides habitat for numerous fish and invertebrate species. Credit Iliana B.
