The elusive baseline of marine disease: Are diseases in ocean ecosystems increasing?
Jessica R. Ward, Kevin D. Lafferty
2004, PLoS Biology (2) 0542-057
Disease outbreaks alter the structure and function of marine ecosystems, directly affecting vertebrates (mammals, turtles, fish), invertebrates (corals, crustaceans, echinoderms), and plants (seagrasses). Previous studies suggest a recent increase in marine disease. However, lack of baseline data in most communities prevents a direct test of this hypothesis. We developed a...
