Bryozoa are a phylum of aquatic invertebrate animals, nearly all forming sedentary colonies. Typically about 0.5 millimetres long, they are filter feeders that sieve food particles out of the water using a retractable lophophore, a "crown" of tentacles lined with cilia. Most marine species live in tropical waters, but a few occur in oceanic trenches, and others are found in polar waters. One class lives only in freshwater environments, and a few members of a mostly marine class prefer brackish water. 5869 living species are known. One genus is solitary and the rest are colonial.
Industrial waste is the waste produced by industrial activity which includes any material that is rendered useless during a manufacturing process such as that of factories, mills, and mining operations. Types of industrial waste include dirt and gravel, masonry and concrete, scrap metal, oil, solvents, chemicals, scrap lumber, even vegetable matter from restaurants. Industrial waste may be solid, semi-solid or liquid in form. It may be hazardous waste or non-hazardous waste. Industrial waste may pollute the nearby soil or adjacent water bodies, and can contaminate groundwater, lakes, streams, rivers or coastal waters. Industrial waste is often mixed into municipal waste, making accurate assessments difficult. An estimate for the US goes as high as 7.6 billion tons of industrial waste produced annually, as of 2017. Most countries have enacted legislation to deal with the problem of industrial waste, but strictness and compliance regimes vary. Enforcement is always an issue.
Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment. For example, releasing inadequately treated wastewater into natural water bodies can lead to degradation of aquatic ecosystems. In turn, this can lead to public health problems for people living downstream. They may use the same polluted river water for drinking or bathing or irrigation. Water pollution is the leading worldwide cause of death and disease, e.g. due to water-borne diseases.
The Yamuna is the second-largest tributary river of the Ganga and the longest tributary in India. Originating from the Yamunotri Glacier at a height of 6,387 metres (20,955 ft) on the southwestern slopes of Banderpooch peaks of the Lower Himalaya in Uttarakhand, it travels a total length of 1,376 kilometres (855 mi) and has a drainage system of 366,223 square kilometres (141,399 sq mi), 40.2% of the entire Ganga Basin. It merges with the Ganga at Triveni Sangam, Prayagraj, which is a site of the Kumbh Mela, a Hindu festival held every 12 years.
The Madison River is a headwater tributary of the Missouri River, approximately 183 miles (295 km) long, in Wyoming and Montana. Its confluence with the Jefferson and Gallatin rivers near Three Forks, Montana forms the Missouri River.
The Barada is the main river of Damascus, the capital city of Syria.
Penobscot Bay is an inlet of the Gulf of Maine and Atlantic Ocean in south central Maine. The bay originates from the mouth of Maine's Penobscot River, downriver from Belfast. Penobscot Bay has many working waterfronts including Rockland, Rockport, and Stonington, and Belfast upriver. Penobscot Bay is between Muscongus Bay and Blue Hill Bay, just west of Acadia National Park.
Tetracapsuloides bryosalmonae is a myxozoan parasite of salmonid fish. It is the only species currently recognized in the monotypic genus Tetracapsuloides. It is the cause of Proliferative Kidney Disease (PKD), one of the most serious parasitic diseases of salmonid populations in Europe and North America that can result in losses of up to 90% in infected populations.
The Greenbrier River is a tributary of the New River, 162 miles (261 km) long, in southeastern West Virginia, in the United States. Via the New, Kanawha and Ohio rivers, it is part of the watershed of the Mississippi River, draining an area of 1,656 square miles (4,290 km2). It is one of the longest rivers in West Virginia.
Wills Creek is a 38.6-mile-long (62.1 km) tributary of the North Branch Potomac River in Pennsylvania and Maryland in the United States.
The Coxs River, a perennial river that is part of the Hawkesbury-Nepean catchment, is located in the Central Tablelands, Blue Mountains, and Macarthur regions of New South Wales, Australia.
Surface runoff is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and that the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas do not allow water to soak into the ground. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin.
Lake Pamvotida or Pamvotis, commonly also Lake of Ioannina is the largest lake of Epirus, located in the central part of the Ioannina regional unit in northern Greece. The regional capital Ioannina to the west and the town of Perama to the north are urban settlements fringing the lake while the remaining of its periphery is composed of farmland. The lake features small fishing ports and a boating port. There is a regular boat service to the Ioannina Island. The Greek National Road 6 surrounds the northern half of the lake.
Jellyella is a genus of bryozoans in the family Membraniporidae.
Lake Akşehir is a tectonic freshwater endorheic lake in Afyonkarahisar and Konya provinces, southwestern part of Turkey. It carries the same name as the town Akşehir south of the lake.
Spring Creek Debris Dam is an earthfill dam on Spring Creek, a tributary of the Sacramento River, in Shasta County in the U.S. state of California. Completed in 1963, the dam, maintained by the U.S. Bureau of Reclamation, serves primarily to collect severe acid mine drainage stemming from the Iron Mountain Mine. The dam forms the Spring Creek Reservoir, less than 1 mile (1.6 km) long. Spring Creek and South Fork Spring Creek flow into the reservoir from a 16-square-mile (41 km2) watershed. The dam is directly upstream from the city of Keswick, California and the Keswick Reservoir. The operation is part of the Trinity River Division of the Central Valley Project.
Adlumia is a genus of two species in the family Papaveraceae. One species, Adlumia fungosa, is commonly known as the Allegheny vine, climbing fumitory, or mountain fringe. It is found in the eastern US, north of VA and TN, as far west as IA and MN, as well as in eastern Canada. The other species, Adlumia asiatica, is native to Korea and immediately neighbouring parts of China and southeast Russia.
The Laurel Fork is a 15.7-mile-long (25.3 km) stream in Virginia and West Virginia, United States. The stream flows north from Highland County, Virginia, where its source and the majority of its length is located, to its mouth in Pendleton County, West Virginia. Laurel Fork is a tributary to the North Fork South Branch Potomac River, making it a part of the Potomac River watershed. The area surrounding Laurel Fork is home to several plant and animal species found nowhere else in Virginia, and is a prime example of a northern boreal forest in the state.
Saccosporidae is a family of myxozoans. It is the only family within the class Malacosporea and has only three species, while the other class of Myxozoa, Myxosporea, includes more than a thousand.
Beania magellanica is a species of colonial bryozoan in the family Beaniidae. It has a cosmopolitan distribution, occurring in shallow waters in the Atlantic and Pacific Oceans and in Antarctica.
