Provides new look at conservation of threatened coral species
An international research team has identified a family of corals found only in the Atlantic Ocean-a first for such classifications in that ocean-in a study that could transform how corals are viewed and classified. The scientists, who will publish their results in the Feb. 26 issue of the journal Nature, say the findings are also important for future decisions about coral conservation and the preservation of threatened biodiversity regions.
Led by Nancy Knowlton of the Scripps Institution of Oceanography of the University of California, San Diego, the study revealed significant flaws in the widely accepted taxonomy of Pacific and Atlantic corals. The team, which included researchers from the Smithsonian Tropical Research Institute in Panama, used DNA analysis to uncover a significant and previously undetected divergence between Pacific and Atlantic corals. Unexpectedly, the researchers found that about one-third of Atlantic corals, which had been conventionally classified in two distinct families found around the tropics, are in fact very closely related. But, the report says, the Atlantic corals are very different from Pacific corals assumed to be their close relatives. The two corals are so distinct, the scientists suggest the Atlantic variety constitutes its own family, making them the first such grouping unique to the Atlantic Ocean.
