This species is capable of rapid nutrient uptake and growth when environmental conditions This species is capable of rapid nutrient uptake and growth when environmental conditions are favourable Lapointe and Ryther, ; Lapointe et al.

Under high light and nutrient conditions, G. Excessive biomass also causes habitat destruction, oxygen depletion, alteration of trophic structure and biogeochemical cycles, and seagrass die-off Valiela et al.

The bloom formation within its native range suggests that if environmental conditions were suitable invasive behaviour may occur in its non-indigenous range. The first published description of the species now known as Gracilaria tikvahiae was as Sphaerococcus multipartitus var.

Agardh from specimens collected in the North River, New York. Following the transfer of S. Agardh, Harvey made the combination Gracilaria multipartita var. Taylor transferred the variety to Gracilaria foliifera in Evidence mounted that the taxon could not be assigned to Gracilaria foliifera and, inMcLachlan described it as a new species: Axes terete to markedly flattened, especially basally, with short, more slender laterals with spinous branchlets. Morphology can range from thin to thick and entirely flat to terete, with morphologically different specimens often found growing on the same rock Gurgel and Fredericq, Spermatangia in textorii-type sori, scattered over the surface of the thallus.

Under non-stressed conditions G. Cultivated plants sold in markets in Hawaii are characteristically dark green, almost black Abbott, Plants do not adhere well to paper. The species is also reported from the Caribbean and South America Taylor, As this species is capable of forming excessive biomasses in eutrophic coastal waters, G. It was introduced to the Hawaiian Islands for mariculture, and continues to be cultivated there. The species is also a popular ornamental plant in the aquarium trade Littler and Littler, The distribution in this summary table is based on all the information available.


When several references are cited, they may give conflicting information on the status. Further details may be available for individual references in the Distribution Table Details section which can be selected by going to Generate Report. Because of its rapid growth by vegetative propagation in aquaculture systems Lapointe, ; Ryther et al.

It can be found from the intertidal to depths of 50 m Dawes and Mathieson,but is most common in shallow waters of m where it can form blooms under favourable environmental conditions, including nutrient enrichment Lapointe, A critical assessment of the systematics of the family Gracilariaceae, based on rbc L sequence analysis, identified nine distinct evolutionary clades within the genus Gracilaria Gurgel and Fredericq, All species in the group display a persistent, large post fertilization fusion cell.
