Mode of zooxanthella transmission does not affect zooxanthella diversity in acroporid corals

Two distinct modes of algal endosymbiont acquisition exist in corals, a direct transmission from the parental colony to the eggs and a larval or post-larval uptake from the environment. The former, maternaltransmission mode is expected to be a more closed system, while the latter is believed to be an open system. Here we test the hypothesis that the diversity of symbionts in closed systems is lower than that in open systems. We examine the identity and diversity of the algal endosymbionts (zooxanthellae) in 25 Montipora species sampled from Irian Jaya (Indonesia) and Magnetic Island (central Great Barrier Reef) and compare the results with those previously obtained from Acropora species, whi..
