G. tikvahiae can withstand rapid decreases in salinity (Lapointe et al., 1984c) and stores nitrogen in its tissues (Lapointe, 1981), which provides a competitive advantage in eutrophic estuaries. Under non-stressed conditions G. tikvahiae are olive-brown to dark purple, although the colour of the plant can range from yellowish green to almost black, and red when dry. Classification: Rhodophyta, Rhodophyceae, Gigartinales (or Gracilariales), Gracilariaceae . Gracilaria tikvahiae, a highly morphologically variable red alga, is one of the most common species of Gracilariaceae inhabiting Atlantic estuarine environments and the Intracoastal Waterway of eastern North America.Populations of G. tikvahiae at the extremes of their geographic range (Canada and southern Mexico) are subjected to very different environmental regimes. the water (Hwang, Williams and Brinkhuis 1987). 1984.

Although the species is not reported as invasive it can negatively impact and even displace other indigenous species due to the formation of massive blooms (Lapointe and Bedford, 2007). , 2008, www.botany.hawaii.edu/invasive/updated_partial_list_of_introductions.htm, www.hawaii.edu/reefalgae/invasive_algae/rhodo/gracilaria_tikvahiae.htm, Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License a algae. 5/6 ):437-440. http: //www.sciencedirect.com/science/journal/15689883 gracilaria tikvahiae common name increases above 8.0 Lee County, Florida USA...
