Location of Repository Nutritional composition and physicochemical properties of two green seaweeds (Ulva pertusa and U. intestinalis) from the Pattani Bay in Southern Thailand . St Andrews BioBlitz 2016. U. prolifera samples were collected in June 2018 from Pyropia rafts (33. Marine Environment Resource Mapping And Information Database (MERMAID): Marine Nature Conservation Review Survey Database. 1998). Centre for Environmental Data and Recording, 2018. 2002. 2003). Ulva intestinalis is a conspicuous bright grass-green seaweed, consisting of inflated irregularly constricted, tubular fronds that grow from a small discoid base. † Populations may not be currently present. Dickinson, C.I., 1963. The location of the samples is on the sea of the Subei. Lubchenco, J., 1978. Such a seed bank allowed U. intestinalis to begin growing two months earlier than many native species, enabling it to escape herbivory and nutrient competition. Lake Michigan Field Station, 1431 Beach St., Muskegon, MI 49441-1098 (231) 759-7824 2000. The reduction of pollution and nutrient run-off could decrease the viable habitat for U. intestinalis. Propagule banks, herbivory and nutrient supply control population development and dominance patterns in macroalgal blooms.

Plants may be branched or unbranched. The increasing use of seaweeds in European cuisine led to cultivation initiatives funded by the European Union. Acta Oceanologica, 20, 259-265. U. prolifera samples collected in June 2018 floated on the sea (36. Associated fauna Plant species diversity in a marine intertidal community, importance of herbivore food preference and algal competitive abilities.

AU - Mayers, Joshua. Reed, R.H. & Russell, G., 1979. In these regions, U. intestinalis may form green tides and biofouling mats that cause cascading effects throughout the food web. The effects of some trace metals on marine phytoplankton. False northern thread (Pseudothrix borealis) is much narrower (~ 1 mm) than U. intestinalis (~ 5 mm) and typically only reaches about 10 cm in length. However, the harmful bloom development seen in marine environments is rare in inland, freshwater populations (Messyasz and Rybak 2011). Journal of Experimental Marine Biology and Ecology 206(1-2): 203-221. 1984). Link and Enteromorpha intestinalis (L.) from the Adriatic Sea. Netherlands Journal of Aquatic Ecology 28(1): 25-33. Origin of species name Amsler, C.D. South East Wales Biodiversity Records Centre, 2018. Simons, J. 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). Branching may be inversely related to salinity. A fluctuating salinity regime mitigates the negative effects of reduced salinity on the estuarine maroalga, Enteromorpha intestinalis (L.) link. Royal Botanic Garden Edinburgh Herbarium (E). Journal of Ecology, 67, 65-77. Such mats of unattached Ulva intestinalis are most frequent in summer. Edwards, D.M., R.H. Reed, and W.D.P. Ulva intestinalis provides shelter for the orange harpacticoid copepod, Tigriopus brevicornis, and the chironomid larva, Halocladius fucicola (McAllen, 1999). Floating masses McAvoy, K.M., and J.L.
