Ecology and biodiversity of the Montastraea "annularis" reef corals species complex

The reef coral know to scientists as Montastraea "annularis" has long held the interest of coral reef ecologists because it is one of the most dominant corals of Caribbean reefs. Recent discoveries have led investigators to conclude that modern Montastraea "annularis," long thought to represent one species, consists of a complex of three different species. Although these three species can be distinguished by growth form, traditional measurements of internal structures used to differentiate M. "annularis" from other corals do not distinguish these three species from each other. Measurements of less commonly used internal structures were measured on collected specimens to determine if they vary among the three species. Finding internal structures that can be used in identifying these species is important to ecologists and paleontologists who may not have samples that display growth form. Additional data must be collected before conclusions can be drawn regarding the non-traditional measurements. In addition, transect data of species distribution across the reef was analyzed to quantify their ecological distribution. These data show a significant difference in the water depth preference of each species. M. faveolata favors shallower depths, M. franksi deeper depths and M. annularis s.s. mid depths. Understanding of the differences among species and their distribution is important for evaluation of ecosystem health and to understand the loss of biodiversity plaguing our world today.
