Brief description

Growth of the two most common Halimeda species (H. copiosa and H. opuntia) was studied at 4 sites on Davies Reef over 6 tagging periods between February 1981 and February 1982. Comparative data was collected from Myrmidon Reef for one tagging period (November 1981 to January 1982). \n \nA total of 1685 branch tips were tagged over the period of a year during visits to the reef at approximately 2-month intervals. New growth was recorded by detailed drawings mid-way and at the end of the period. If growth was too complex to record in the field, those samples were collected and taken back to the laboratory; new batches were tagged as replacements. The laboratory samples were photocopied, dried and weighed, and the total surface area measured with a Licor LI-3000 area meter. \n \nVariables recorded were: days, number of samples, time of year (Feb/Mar, Apr/May, Jun/Aug, Aug/Oct, Oct/Dec, Dec/Feb).
