This fern has been introduced to other parts of the world, including the United Kingdom, where it has become a pest in some areas. A nominally tropical plant, it has adapted to the colder climate. · Native to California, the mosquitofern plant, Azolla filculoides or just Azolla, is named thus due to its habitat. While the plant starts off as small as ¼ inch (5 mm.), mosquitofernhabitat is that of a matting, aquatic plant that can double its size in a couple of days! Mosquitofern is a native species and has some value as wildlife food and habitat. Fish, amphibians, reptiles, and ducks may eat the plants on occasion, and dense colonies provide habitat for some insect species. mosquitofern, (genus Azolla), genus of six or seven species of aquatic ferns of the family Salviniaceae. Members of Azolla are distributed nearly worldwide but are most diverse in tropical regions. Mosquitoferns float on the surface of still, fresh waters, sometimes becoming stranded on muddy banks. Their name is an allusion to the fact that the ...See full list on britannica.comMosquito ferns are very small plants, often less than 2.5 cm (1 inch) long. The tiny leaves are in two alternating rows on either side of the stem and are divided into an upper green lobe and a lower white to transparent lobe. The sporangia (spore-producing structures) are enclosed in small, structurally complex, globose structures known as sporocarps, with separate sporocarps formed containing either numerous microspores or a single megaspore. Both types of spores are globose (tetrahedral), but an average megaspore is 20 or more times larger than a microspore. The highly reduced gametophytes (gamete-producing structures), which develop underwater, are mostly contained within the spore walls.Britannica QuizSee full list on britannica.comAzolla is one of the most important ferns in agriculture. More money has been spent on its study and more scientific papers have been published involving this genus than on any other fern. Long ago, farmers in Vietnam and other parts of Southeast Asia discovered that rice fields in which mosquito ferns were released produced higher yields of grain. For centuries, families jealously guarded their individual strains of Azolla, keeping them alive in containers between plantings and inoculating the fields at the beginning of each crop cycle.The secret behind the use of mosquito fern as a “super fertilizer” is that within cavities of the green upper lobe of the leaves, there live colonies of a cyanobacterium, Anabaena azollae. These photosynthetic bacteria have the ability to transform atmospheric nitrogen into nitrate fertilizer. When individual plants of Azolla die, this nitrate fertilizer is released into the environment, where it becomes available to other plants. In addition to its use in rice fields, Azolla has been shown to benefit the cultivation of some other crops grown in paddies, such as taro. The plants have also been used in livestock and poultry feed.See full list on britannica.com This fern has been introduced to other parts of the world, including the United Kingdom, where it has become a pest in some areas. A nominally tropical plant, it has adapted to the colder climate. Eastern mosquito fern is a native annual aquatic plant in the Water-fern family (Salviniaceae). It is widespread in eastern North America and northern South America, growing in still or very slow-moving water, shallow ponds, ditches and sluggish streams. Although in its native range mosquitofern provides habitat for wildlife and fish, the habitat it provides is one of lesser quality than that it replaces. This leads to decreased dissolved oxygen concentration and light penetration, decreased pH levels and nutrient richness and lower water quality. · Dense colonies of mosquitofern provide habitats for many micro and macro invertebrates. They are used as food by fish and other wildlife species (e.g. amphibians, reptiles, ducks, etc.). Eastern mosquito fern is a native annual aquatic plant in the Water-fern family (Salviniaceae).
