Causes and Consequences of Coral Decline
March 30, 2009
Josh Idjadi research scientist, New England Aquarium

Josh Idjadi discusses the scientific debate about the causes of the decline of coral reefs, looks at how this might affect the associated reef community, and talks about the recent recovery of a potentially essential algae-eating urchin.

Much of Idjadi’s work has focused on the role of corals in providing habitat for other reef-dwelling organisms and the importance of algae-eating urchins in maintaining coral-dominated reefs. Research sites have included Jamaica, Australia, and Moorea in French Polynesia. These sites have provided a variety of coral species to study, not to mention some great underwater views.
