RMRJXK6R–. Atoll research bulletin. Coral reefs and islands; Marine biology; Marine sciences. A major obstacle to understanding the ecological role of siphonaceous algae at Twin Cays has been the high biodiversity of the taxonomically problematical genera named above. Six distinct species ofAvrainvillea co-occur in the creeks, ponds and lakes of Twin Cays (Figs. 6,7). Using treatments prior to the beginning of this investigation (Taylor, 1960; Norris and Bucher, 1982), it would have been possible to discern only a small fraction of the taxa that are actually present. As one example, Avrainvillea longic

Coral reefs and islands; Marine biology; Marine sciences. 16 We also discovered unexpected evidence in further support of the coloniality hypothesis in the case of Avrainvillea longicaulis f. laxa. We found that the colonial morphology is uniquely reinforced by the intermingling of blade and stipe siphons at areas of contact (Figs. 19,25). Contact frequently occurs for prolonged periods in such calm habitats, leading to abundant anastomosing points of fusion/adhesion.. Figure 18.

Unlike other Bryopsidales, species of Avrainvillea are long-lived (see Littler and Littler, 1992) and do not undergo holocarpy [i.e., mass synchronous sporogenesis (Clifton, 1997) fo
