Tyler Morning Telegraph, TylerPaper.com, Tyler, TX. The rate of growth of Salvinia molesta (S. Auriculata Auct.) Management alternatives for salvinia include the three traditional weed management methods: mechanical, chemical, and biological control. Wunderlin, R.P. Keener, B. R., A.R. Salvinia's growth, expressed as frond production and plant fresh weight doubling time, was significantly increased with increasing nitrogen concentration from 1.0 mg/1 to 100.0 mg/1 in the growth media. The upper surface of the floating leaves are covered in hairs that repel water. 1979. Nature 320(6063):581-584. I. Pteridophyta. http://www.herbarium.org. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. Pursley, D. Diaz, and W. Devers.

Alabama state survey map for Salvinia … Effects of adult and larval Cyrtobagous salviniae on the floating weed Salvinia molesta. Smart, and C.S. [16]. Growth rates for Salvinia molesta from Lake Kariba have been calculated in axenic laboratory cultures and compared with those of S. minima by Gaudet (1973). Salvinia molesta Mitchell does it threaten Florida? Texas A&M University Bioinformatics Working Group. 2010.

Trinity River NWR, US Fish and Wildlife Services, Liberty, TX. 2007. 3 populations of S. minima are currently recorded from 14 states, and infestations are considered problematic in both Texas and Louisiana (Jacono et al. Pesky invasive plant turns up in another east Texas waterway. Created on 04/03/2007. 1966. Four hairs are joined at the tips and resemble a wisk. More than 99% of the Pascagoula River population was killed by storm surge salinity or by being deposited on land during Hurricane Katrina in 2005, thus leaving about 2 hectares of. Carlson. Louisiana State University Herbarium - Vascular Plants. Richerson, and V. Howard. It is usually referred to as common salvinia or water spangles. 2015. Bernice Pauahi Bishop Museum natual history data. Flores and Carlson (2006) noted a 2.5 fold increase in dissolved oxygen by removing 90% of S. molesta at five east Texas sites. Floating mats of S. molesta can be up to one meter thick (Whiteman and Room 1991), impeding navigation, reducing water flow and interfering with fishing and recreational activities (Mitchell and Thomas 1972). Giant salvinia (Salvinia molesta) is a free-floating aquatic plant that originates from Brazil.It is an invasive species in over 21 countries. Salvinia molesta demonstrates tolerance to freezing air temperature, but cannot withstand ice formation on the water surface except when dense mats protect the underlying plants (Whiteman and Room 1991). Reproduction occurs mainly from fragmentation. Local movement between waterbodies may be facilitated by birds and aquatic mammals (Mitchell and Thomas 1972). University of Alabama, Tuscaloosa, AL. However, the sporangial sacs are usually empty of microscopic spores or with only a few deformed remnants. Aquatic Botany 40:27-35. http://www.tylerpaper.com/article/20080214/SPORTS0202/802130364. EDDMapS: Early detection and distribution mapping system. During earlier stages of colonization S. minima demonstrates exponential growth rates. Three growth forms have been described where individual leaves can range from a few millimeters to 4 centimeters in length. US Department of Agriculture Animal & Plant Health Inspection Service, Plant Protection & Quarantine, and Cooperative Agricultural Pest Survey (CAPS), West Lafayette, IN. Bister, T.J., and M.W. Jacono, M.M. University of South Florida]. Under favorable natural conditions, biomass can double in about one week to 10 days (Mitchell and Tur 1975; Mitchell 1979). 1982. The University of Georgia, Tifton, GA. http://www.eddmaps.org. 2004; Mitchell et al. 1980. 1980. 2008 (February 14). and P.M. Room. It has been recorded blanketing waterways 19.3km long and 110m wide and mats have been measured as thick as 20-25cm (7.9-9.8"). Extirpated from colder climate states (Connecticut, District of Columbia, Kansas, Missouri, Virginia) and eradicated from Northern Alabama and California, and parts of the Carolinas, Florida, and Texas.
