The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wimmera River
The Wimmera River, an inland intermittent river of the Wimmera catchment, is located in the Grampians and Wimmera regions of the Australian state of Victoria. Rising in the Pyrenees, on the northern slopes of the Great Dividing Range, the Wimmera River flows generally north by west and drains into Lake Hindmarsh (Wergaia: ''Gurru'') and Lake Albacutya (Wergaia: ''Ngelbakutya''), a series of ephemeral lakes that, whilst they do not directly empty into a defined watercourse, form part of the Murray River catchment of the Murray-Darling basin. Course and features The Wimmera River rises in the Great Dividing Range below , between and , and flows generally north and west, through , , and , also forming the eastern boundary of the Little Desert National Park. It is joined by fourteen minor tributaries, including the Mackenzie River, before reaching its mouth at Lake Hindmarsh, near Jeparit. The river descends over its course.

Taxa Named By Tarmo Ain Raadik
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macrophytes
Aquatic plants are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife. Macrophytes are primary producers and are the basis of the food web for many organisms. They have a significant effect on soil chemistry and light levels as they slow down the flow of water and capture pollutants and trap sediments. Excess sediment will settle into the benthos aided by the reduction of flow rates caused by the presence of plant stems, leaves and roots. Some plants have the capability of absorbing pollutants into their tissue. Seaweeds are multicellular marine algae and, although their ecological i ...

Billabong
Billabong ( ) is an Australian term for an oxbow lake, an isolated pond left behind after a river changes course. Billabongs are usually formed when the path of a creek or river changes, leaving the former branch with a dead end. As a result of the arid Australian climate in which these "dead rivers" are often found, billabongs fill with water seasonally but can be dry for a greater part of the year. Etymology The etymology of the word ''billabong'' is disputed. The word is most likely derived from the Wiradjuri term ''bilabaŋ'', which means "a watercourse that runs only after rain". It is derived from ''bila'', meaning "river", It may have been combined with ''bong'' or ''bung'', meaning "dead". One source, however, claims that the term is of Scottish Gaelic origin. Billabongs were significant because they held water longer than parts of rivers; it was important for people to identify and name these areas.

Anabranch
An anabranch is a section of a river or stream that diverts from the main channel or stem of the watercourse and rejoins the main stem downstream. Local anabranches can be the result of small islands in the watercourse. In larger anabranches, the flow can diverge for a distance of several kilometers before rejoining the main channel. Word usage and related terms The term ''anabranch'', in its hydrological meaning, is used more frequently in Australia than in the rest of the English-speaking world. The term ''anabranching river'' describes a river with many anabranches, whilst an anastomosing river is an organic-rich subset of this river type. The term braided river describes watercourses which are divided by small islands into multiple channel threads within a single main channel, but the term does not describe the multiple channels of an anabranching river. A distributary is a branch of a river that does not rejoin the main channel; these are common on and near river d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fitzroy River (Victoria)
The Fitzroy River, a perennial river of the Glenelg Hopkins catchment, is located in the Western District of Victoria, Australia. Course and features The Fitzroy River rises below Mount Vandyke in the Cobboboonee National Park, near the western edge of the Lower Glenelg National Park.

Lake Corangamite
Lake Corangamite , a hypersaline endorheic lake, is located near Colac in the Lakes and Craters region of the Victorian Volcanic Plains of south-west Victoria, Australia. The lake's salinity levels have increased dramatically as the lake level has dropped in recent decades. It is Australia's largest permanent saline lake, covering approximately with a circumference of . It forms part of the Ramsar-listed Western District Lakes wetland site. The indigenous name of the lake is recorded as ''Kronimite''. Physical features and hydrology The waterbody is surrounded to the south and east by rocky outcrops (known locally as the ''stony rises'') which were formed by lava flows from Mount Porndon to the south-west and Mount Warrion to the east. The Red Rock volcanic complex overlooks the south east shore at Alvie. The Mount Warrion flows caused the lake to form by blocking drainage to the east. As is typical of lakes in the area, the eastern flanks of the lake consist of lunettes for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
