Salvinia minima is a species of aquatic, floating fern that grows on the surface of still waterways. [1] It is usually referred to as common salvinia or water spangles . Salvinia minima is native to South America, Mesoamerica, and the West Indies and was introduced to the United States in the 1920s–1930s. [ 2 ]
Salvinia or watermosses [1] is a genus of free-floating aquatic ferns in the family Salviniaceae. The genus is named in honor of 17th-century Italian naturalist Anton Maria Salvini , and the generic name was first published in 1754 by French botanist Jean-François Séguier in Plantae Veronenses , a description of the plants found around Verona ...
Salvinia molesta is a complex of closely related floating ferns; they can be difficult to distinguish from each other. This water fern is often grown as an ornamental plant but has escaped and become a noxious pest in many regions worldwide.
Cyrtobagous salviniae is a species of weevil known as the salvinia weevil. It is used as an agent of biological pest control against the noxious aquatic plant giant salvinia (Salvinia molesta). The adult weevil is about 2 millimeters long. It is brown in color during its first few days of adult life and soon turns shiny black.
Salviniales are all aquatic and differ from all other ferns in being heterosporous, meaning that they produce two different types of spore (megaspores and microspores) that develop into two different types of gametophyte (female and male gametophytes, respectively), and in that their gametophytes are endosporic, meaning that they never grow outside the spore wall and cannot become larger than ...
Background Chlorine and caustic soda are produced at chlor-alkali plants using mercury cells or the increasingly popular membrane technology that is mercury free and more energy-
The Salvinia effect describes the permanent stabilization of an air layer upon a hierarchically structured surface submerged in water. Based on biological models (e.g. the floating ferns Salvinia , backswimmer Notonecta ), biomimetic Salvinia-surfaces are used as drag reducing coatings (up to 30% reduction were previously measured on the first ...
