Strong Fidelity

A study reiterates the importance of conserving corals; they tend to grow closer home. A team sampled dna from coral reefs in the Indian Ocean and found that most of the corals in the same reef were kins. This is despite the fact that they lay their eggs in the moving water and the young coral could very well take root elsewhere. The study is out in the May issue of Evolutionary Applications.
