From the Editor

Many thanks to Aileen Morse for her interesting article about chemical cues from coralline algae that are important in stony coral settlement and morphogenesis.

The publications mentioned below include two superb reference books concerning African coasts. Stegenga, Bolton & Anderson have produced a seaweed flora of the west coast of South Africa which comprises approximately 400 species. This includes geniculate coralline algae but not nongeniculate species for which taxa Chamberlain & Keats are preparing a supplement. Keys to genera and species are provided and each species is described and illustrated with drawings, additionally there are 62 colour photographs. Introductory sections concerning the environment, ecology, biogeography and commercial aspects of the seaweeds are also included.

Turning to East Africa, Matt Richmond has edited an excellent guide to more than 1,600 plants and animals; each species is illustrated by a colourful drawing, mostly made by Ann Alexander, and the whole provides an intriguing introduction to the rich tropical/subtropical marine life of the area. Again interesting general sections describe the scientific and working life of the area.

I have some information on the induction of stony coral settlement and metamorphosis that I think will be of interest to readers of Coralline News. I have found what seems to be a common, ancient chemosensory mechanism in four major coral families. All of the species so far looked at in these families have a strict requirement for detection of a particular chemical cue associated with, yes, non-geniculate coralline algae. Larvae are all recognising the same class of molecule, a sulphated glycosaminoglycan of the algal cell walls. Coral species from the Pacific are induced by molecules purified from Caribbean algae as well as Pacific algal congenors. Caribbean coral species similarly recognise cues purified from Pacific as well as Caribbean algae.
