Reproduction Preferences Additional InformationMaerl beds in the Sound of Iona are recorded as containing dead nodules up to 4,000 years old. Insufficient information is available on reproductive frequency, fecundity and developmental mechanism. In Britain there is only one record of a fertile plant (found in July). Consequently virtually all propagation must be presumed to be vegetative and therefore dispersal potential is recorded as low. Plants from Brittany are mostly fertile in winter but Adey and McKibbin (1970) recorded a plant from Spain being fertile in August. Cabioch (1969) suggested Lithothamnion corallioides may have phasic reproduction with peaks every six years. This may account for observed changes in the relative proportions of live Lithothamnion corallioides and Phymatolithon calcareum nodules in maerl beds. Dominance cycles with periods of about thirty years have been recorded on some of the maerl beds of northern Brittany.
