When released, the zoospores leave the reticulated/perforated thallus typical of U. reticulata. Algae. can grow abnormally in bacteria-free culture but develop normal morphology in the presence of their bacterial floras (Provasoli and Pintner, 1980; Nakanishi et al., 1996). Jagtap TG, 1992. Sri Lankan Seaweeds. In: Chlorophyta, Melbourne, Australia: Defence Science and Technology Organisation, Materials Research Laboratories. Mahasagar-Bulletin of the National Institute of Oceanography, 19(1):45-51. However, Ulva and Enteromorpha are, as first thought by Linnaeus, not distinct genera after all, based on ITS nrDNA analysis (Hayden et al., 2003). Ratana-arporn P; Chirapart A, 2006.

Varghese KJ; Sukhumaran TPM; Asokan MA; Syama SH, 2010. Can occur between 20 and 35°C. In Sri Lanka (Indian Ocean), surface water temperature all around the island is between 26 and 28°C (Coppejans et al., 2009) while that in southeast Asia it could range between 20 and 29°C. 11-17. http://www.bentham-open.org/pages/gen.php?file=11TOEBMJ.pdf&PHPSESSID=d9c4305197656f8839fe7149fb33880d DOI:10.2174/1875040000902010011. Viscusi (2011) reported on Bloomberg.com that green tides were keeping tourists away from the coast in Brittany, France. It is likely that U. reticulata after macroalgal blooms alternates in occurrence with other species of algae that are common in eutrophied waters. Phytochemical investigation of seaweed Ulva reticulata from the coast of Bakel, Kasaragod of Kerala State in India. Takeshi S; Yumiko YS; Joko S, 2005. Dispersal may be restricted by range of temperature tolerance and geographical boundaries. (=Enteromorpha) intestinalis), where the alga develops normal thallus morphology only in the presence of bacterial associates and not when they are absent in an axenic culture (Provasoli and Pintner, 1980; Nakanishi et al., 1996; Marshall et al., 2006). In: Estuarine, Coastal and Shelf Science, 83 (3) 333-341. Ruangchuay R; Lueangthuwapranit C; Pianthumdee N, 2007. This video is unavailable. Ateweberhan M; Prud'homme Reine WFvan, 2005.

Boron content of marine algae from Mandaitivu and Kirinda Coasts and mineral content of nine species of algae from the Kirinda Coast. Accidental introduction of U.reticulata is also possible through the transport of seedlings of farmed seaweeds such as the case of Kappaphycus alvarezii introduced from the Philippines to South Pacific island countries such as Fiji, Tonga and the Solomon Islands. The genus Ulva is classified under order Ulvales, class Ulvophyceae, which includes morphologically variable forms that have a life history involving alternation of isomorphic generations consisting of haploid gametophyte and diploid sporophyte. Manila, Philippines: National Bookstore. Wenn du warten kannst, ist es am besten, die Eiscreme vor dem Essen über Nacht einzufrieren. Large volumes of sea lettuce often indicate high levels of pollution. Tsai et al., 2004). they are plant-like as opposed to protozoa which are animal-like protists. Hydrobiologia. Nova Hedwigia, 75(1/2):1-90. Batham EJ, 1956. Kolanjinathan K; Stella D, 2011. This is happening in the South Pacific Island countries where the unintentional transfer of U. reticulata through K. alvarezii ‘seedlings’ prompted these countries to adopt a common quarantine protocol (Sulu et al., 2003). they are multicellular seaweed, most likely the closest ancestor to modern terrestrial plants. Songklanakarin Journal of Science and Technology, 29(4):893-905. Journal of Ocean University of China (Ocean and Coastal Sea Research), 4(3):205-208. ]., Belgium: Belgian Development Cooperation. But effects of macroalgal assemblages are underscored by a study of Tsai et al. A taxonomic survey of seaweeds from Eritrea. Ramirez ME, 2010. Otherwise, no record exists in the literature documenting this species as having been intentionally transferred for any culture purposes. Census of the Queensland Flora., Brisbane, Australia: Queensland Herbarium Biodiversity and Ecosystem Sciences, Department of Environment and Resource Management. They release spores that develop into gametophytes (haploid) that look just like the sporophyte but are then both male and female plants; thus self-fertilization is not possible. Ulva blooms alter water and sediment quality due to organic decomposition and deposition. The sporophyte (spore-producing) generation of U. reticulata produces containers called sporangia which release haploid, quadriflagellated zoospores through meiosis at the middle portion of a mature thallus. Noumea, New Caledonia: Secretariat of the Pacific Community, 84 pp. U. reticulata normally grows attached to rocky substrates but mature thalli easily detach and become free living vegetative algae. Coppejans E, Leliaert F, Dargent O, Gunasekara R, Clerck Ode, 2009. Because of the large surface area of the fronds, sea lettuce grows especially well where there are high levels of nutrients to absorb, and it is thus tolerant of a fair level of pollution. All Rights Reserved. Benthic organisms, such as shelled molluscs that thrive in soft sea bottoms, as well as other sedentary invertebrates that feed on detritus, or that filter seawater for food, are likely to be affected when there is little oxygen available, especially in areas when there is limited water circulation.

It is found in southeast Asia (Indonesia, Malaysia, the Philippines, Singapore, and Vietnam), eastern Indian Ocean (Andaman and Nicobar Islands), southwest Asia (Bahrain, India, Kuwait, Pakistan, Persian Gulf, Saudi Arabia, Sri Lanka), western Indian Ocean (Kenya, Tanzania, Madagascar islands, Somalia, and Mauritius), northern Indian Ocean (southern Red Sea, Eritea, Egypt, eastern Saudi Arabia), east Asia (southern Japan and Korea), mid-Pacific Ocean (Hawaiian Islands), and in Oceania (Papua New Guinea, north Australia).

Ministry of Natural Resources and Environment, Bangkok, Thailand. can cover a wide area of coral reefs, limiting growth of corals and their associated benthic species. Coppejans E, Prud'homme van Reine W F, 1992. Journal of Marine Science, 1(1):53-63. In such events their large biomass competes for space with other bottom-dwelling organisms, by overcrowding and shading thus limiting other species’ mobility to feed and to find mates, in the case of animals, or the ability to photosynthesize, in the case of plants.
