Description:
Macroalgae are important, if not essential, components of coral reef communities (Figure 4.2). While substantially less information is available on deep-water macroalgae than on their shallow-water counterparts, information does exist on their composition, productivity, abundance and potential importance (Gilmartin 1960, Jensen et al. 1985, Littler et al. 1986, Ballantine and Aponte 2003, 2005). Exploration of MCEs has yielded new records and descriptions of macroalgal species using a combination of morphological and molecular techniques. It is currently difficult to determine the degree of depth restriction, given that few mesophotic regions have been adequately sampled. While some mesophotic algal assemblages often contain a combination of shallow- and deep-water macroalgae (Kajimura 1987, Searles and Schneider 1987, Hanisak and Blair 1988), other algal assemblages contain a mesophotic flora composed largely of species unique to the mesophotic (Agegian and Abbott 1985, Spa ...
