Apalanthe
''Elodea'' is a genus of 6 species of aquatic plants often called the waterweeds described as a genus in 1803. Classified in the frog's-bit family ( Hydrocharitaceae), ''Elodea'' is native to the Americas and is also widely used as aquarium vegetation and laboratory demonstrations of cellular activities. It lives in fresh water. An older name for this genus is ''Anacharis'', which serves as a common name in North America. The introduction of some species of ''Elodea'' into waterways in parts of Europe, Australia, Africa, Asia, and New Zealand has created a significant problem and it is now considered a noxious weed in these areas. ''Elodea canadensis'', sometimes called American or Canadian water weed or pond weed, is widely known as the generic water weed. The use of these names causes it to be confused with similar-looking plants, like Brazilian elodea ('' Egeria densa'') or hydrilla (''Hydrilla verticillata''). American water weed is an attractive aquarium plant and is a goo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrocharitaceae Genera
Hydrocharitaceae is a flowering plant family including 16 known genera with a total of ca 135 known species (Christenhusz & Byng 2016), that including a number of species of aquatic plant, for instance the tape-grasses, the well known Canadian waterweed, and frogbit. The family includes both freshwater and marine aquatics. They are found throughout the world in a wide variety of habitats, but are primarily tropical. Description The species are annual or perennial, with a creeping monopodial rhizome with the leaves arranged in two vertical rows, or an erect main shoot with roots at the base and spirally arranged or whorled leaves. The leaves are simple and usually found submerged, though they may be found floating or partially emerse. As with many aquatics they can be very variable in shape – from linear to orbicular, with or without a petiole, and with or without a sheathing base. The flowers are arranged in a forked, spathe-like bract or between two opposite bracts. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish expeditions to the Pacific Northwest, Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as ...

Stormy Lake (Alaska)
Stormy Lake is a lake on the Kenai Peninsula of Alaska, also known as Three Bay Lake. It is located north of the town of Kenai. The lake has been the target of two efforts to eradicate invasive species and re-introduce native flora and fish. Name and location Stormy Lake is a lake on the Kenai Peninsula. It is located within the Captain Cook State Recreation Area. The prevailing winds can sometimes produce whitecaps on the lake, giving it its name. It is also known as ''Three Bay Lake'' because it consists of three nearly separate areas connected by channels. Access to the lake is via the Kenai Spur Highway, about north of Kenai. Facilities include a boat launch, overlook, picnic area, wading/swimming area, and a small, boat-in only campground. |
Aquatic Weed Harvester
An aquatic weed harvester, also known as a water mower, mowing boat and weed cutting boat, is an aquatic machine specifically designed for inland watercourse management to cut and harvest underwater weeds, reeds and other aquatic plant life. The action of removing aquatic plant life in such a manner has been referred to as "aquatic harvesting". Overview Water is an important resource and in many countries, waterways are increasingly clogged by aquatic plant growth. This is particularly so in tropical countries where warmer water means the plants grow more quickly, and increasing run-off of fertilisers and effluent has exacerbated the problem. Irrigation ditches and pumps can become overgrown with vegetation, power station and factory water intakes can get blocked, boats can get hindered, fish stocks can be disrupted, and water moves more slowly, resulting in greater evapotranspiration and a greater risk of flooding. In some large irrigation projects in India, canals have become ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berky Mähsammelboot Elodea
The Berky GmbH (former Anton Berkenheger GmbH & Co. KG) is a German company that manufactures machines, specialized vehicles and boats for water maintenance. The company is based in Haren (Ems) in the Emsland region. History The co-founder, farmer and chairman of the Meersbach Water and Soil Association, Anton Berkenheger received the first patent for a hydraulic, three-wheeled special machines for mowing ditch banks in 1963. Together with the civil engineer Gerhard Knoll and Josef Göcking, he founded Anton Berkenheger & Co. KG in Haren-Erika.By 1968, they already employed 15 people.

Fluridone
Fluridone is an organic compound that is used as aquatic herbicide often used to control invasive plants. It is used in the United States to control hydrilla and Eurasian watermilfoil among other species. Fluridone is sold as a solution and as a slow release solid because the herbicide level must be maintained for several weeks. The compound is a colorless solid.Franz Müller and Arnold P. Applebyki "Weed Control, 2. Individual Herbicides" in Ullmann's Encyclopedia of Industrial Chemistry 2010 The compound was first reported as a possible herbicide for cotton fields in 1976. It was registered with the U.S. Environmental Protection Agency in 1986 and has low toxicity to animals with no restrictions on swimming or drinking in treated water bodies. Fluridone breaks down in the environment over days or weeks with the major degradation product being N-methyl formamide. The half-life of fluridone in soils and sediments has been estimated at nine months. Fluridone degradation in soil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
