The phylogenetic tree was constructed by the ML algorithm of the MEGA 6 program. Journal of Phycology 34: 319-340. 2000. In such conditions, grazing pressure often cannot control massive blooms (Lotze et al. 2002. However, populations are greatly reduced or possibly no longer present in the Wolf Creek drainage due to decreased salinity (Marcus et al. 1998. What I can only describe as a compact dark spongy moss type algae have taken over where the once Ulva proliferated. 1976. 1994. Internationally, Ulva intestinalis has also been associated directly or in part with negative impacts on diversity or specific taxa. Bahram, and A.A.S. Sea Lettuce (Ulva lactuca) Appearance: Green seaweed, sheetlike in appearance. Species within the genus Ulva are difficult to identify. In Ohio, U. intestinalis has been recorded from shady regions of the Portage River, where there is almost no flow in shallow bedrock pools created by upwelling through limestone faults (Taft 1964). Marine Ecology Progress Series 284: 109-116. intestinalis, Ulva compressa var. I put some in my Gourmet grazer and most my fish love to eat it so we also get free food.

(2000) found that this species can produce a propagule bank capable of surviving winter conditions in the Baltic Sea. Description: Compressed, elongated, hollow fronds with a green colour. Note: Check federal, state/provincial, and local regulations for the most up-to-date information. Potential: Ulva intestinalis has caused serious negative impacts in marine and coastal areas outside of the Great Lakes region. 2004, Vadas and Beal 1987). Can be found from the upper to the lower shore, in both sheltered and exposed conditions. Where suitable support is available, it will grow on rocks, mud, sand and in rock pools. Mats can also shade out native seagrass beds (Cummins et al. Fong, P., K.E. 1984). Until they were reclassified by genetic work completed in the early 2000s, the tubular members of the sea lettuce genus Ulva were placed in the genus Enteromorpha. are tan to brown delicate filamentous algae7.

Swarmer release and distribution of life-cycle phases of Enteromorpha intestinalis Chlorophyta in relation to environmental factors. They disperse well, as they are positively phototactic and thus can remain high in the water column, allowing them to be carried far away from parent populations (Hoffman and Camus 1989).

Although growth is typically positively related to salinity, many populations can survive and grow in freshwater conditions, and the negative effects of low salinity can be offset by increased nutrient concentrations. Oliveira, M.R. Biological There are no known biological control methods for this species. Oikos 89: 46-58. Ulva intestinalis has a moderate environmental impact in the Great Lakes. The sea lettuces comprise the genus Ulva, a group of edible green algae that is widely distributed along the coasts of the world's oceans. However, if environmental factors, such as salinity are taken into account, branching can be used to identify the great majority of thalli correctly (Blomster et al., 1998). 2001. It is also a common epiphyte on other algae and shells. A fluctuating salinity regime mitigates the negative effects of reduced salinity on the estuarine maroalga, Enteromorpha intestinalis (L.) link. 1986. Kamer, K., P. Fong, R. Kennison, and K. Schiff. American Journal of Botany 89(11): 1756-1763.

The effect of salinity on the growth rate of the macroalgae Enteromorpha intestinalis (Chlorophyta) in the Mondego estuary (west Portugal). Ulva fasciata is commonly found on intertidal rocks, in tidepools, and on reef flats. In very sheltered conditions, plants that have become detached from the substrate can continue to grow, forming extensive floating communities. Lotze, H.K., and B. Alstroem-Rapaport, C., and E. Leskinen. Ulva intestinalis is a conspicuous bright grass-green seaweed, consisting of inflated irregularly constricted, tubular fronds that grow from a small discoid base.

Identification is heavily reliant on cell detail and cell arrangement, in addition to gross morphology, but complicated by the fact that the morphology of a single species can vary in response to environmental conditions. U. intestinalis is a vibrant green, filamentous algae which often attaches to substrate7. Habitat hidupnya adalah berada di daerah perairan payau, dan laut. 2005. 2004. Where suitable support is available, it will grow on rocks, mud, sand and in rock pools. Catling, P.M., and W.G. Messyasz, B., and A. Rybak. McAvoy, K.M., and J.L. Can be free-floating in the water or attached to rocks, pilings and other hard surfaces.

This kelp has a two-phase life cycle that alternates between the large, spore-forming stage (sporophyte) and the microscopic, gamete-producing stage (gametophyte). Ulva intestinalis populations around the world consist of various ecotypes that are somewhat genetically different from each other, each specifically adapted to grow best in a different salinity regime. Establishment of freshwater biota in an inland stream following reduction of salt input. 2003). Gametes are biflagellate and zoospores are typically quadriflagellate. Reed, R.H., and G. Russell. This study illustrated some nutritional value of two marine algaes (U. rigida and U. intestinalis) which belong to the division chlorophyta. Holt, G. 1980. Species with hollow, one-layered thalli were formerly included in Enteromorpha, but it is widely accepted now that such species should be included in Ulva. Marine Ecology Progress Series 256: 63-74.

State Rd., Ann Arbor, MI 48108-9719 (734) 741-2235 Epibionts like Ulva can also exert increased drag on snails living in high flow conditions, causing them to invest more energy in foot muscles and less in growth (Wahl 1996).

Ulvan is the water-soluble polysaccharide found in green seaweeds of the order Ulvales. Journal of Experimental Marine Biology and Ecology 126: 281-291. For instance, Ulva intestinalis and Ulva compressa (as Enteromorpha) are two distinct, genetically divergent and reproductively isolated species (Blomster et al., 1998). Common all round the coasts of Britain and Ireland. The latter are generally not well adapted to low salinity values and extended periods of desiccation. ''Ulva intestinalis'' is a green alga in the family Ulvaceae, known by the common names sea lettuce, gutweed and grass kelp. Habitat: Can survive freshwater input, often found in the upper intertidal in stagnant or brackish pools. Nutrient limitation of the macroalgae Enteromorpha intestinalis collected along a resource gradient in a highly eutrophic estuary. Ulva intestinalis mats can deplete the available oxygen in the water and increase the production of hydrogen sulphide in the sediment, which can cause population declines in other fauna and flora (Bäck et al. 2004) and negatively impact their corresponding communities, as well disrupt feeding by wading birds (Raffaeli et al. Abiotic factors affecting the development of Ulva sp. Location and habitat of Ulva species taken from GenBank [3,12]. Ulva dapat hidup di air payau, air asin, atau menempel pada kayu-kayu dan batu-batu sepanjang pantai. Fronds are typically unbranched. Size 6 to 24 inches Habitat.

Mats of U. intestinalis in England also caused an order of magnitude decrease in abundance of the economically important bivalve Cerastoderma edule (Romano et al. 1978. Ulva memiliki talus berupa lembaran yang terdiri dari dua lapis sel. intestinalis mats on near-bed currents and sediment dynamics: flume studies. (2003) observed in England an increase in friction drag with the presence of Ulva intestinalis mats, causing a 10% to 56% reduction in current velocities.
