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] |
Genoa River
Genoa River is a perennial river located in the Monaro region of New South Wales and flows into the East Gippsland region of Victoria in Australia. It used to be known as Bondi Creek or Yard Creek.

Course and features Genoa River rises below Nungatta Mountain, south of Bombala in New South Wales, and flows generally north, then south, crossing the Black-Allan Line that forms part of the border between Victoria and New South Wales, and then southeast flowing through the Coopracambra National Park, joined by fifteen tributaries including the White Rock River and Wallagaraugh River, before reaching its river mouth of the Tasman Sea of the South Pacific Ocean at the Mallacoota Inlet in Victoria. The river descends over its course. The Monaro Highway crosses the river in its upper reaches between Bombala and Cann River; and the Princes Highway crosses the river in its lower reaches at Genoa.

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] |

Euastacus Yanga
''Euastacus yanga'', also known as the variable spiny cray, is a freshwater crayfish endemic to south eastern Australia. Description The maximum recorded size was OCL (Occipital Carapace Length) which is used to measure the species' size. The rostrum is short and in individuals over OCL usually does not reach the base of the third antenna segment. In those measuring OCL the rostrum is to the base or midpoint of that segment and, in some under , goes to the end of the third segment. The cephalon is spiny on most organisms but less so on specimens under OCL. In southern populations the spines are larger and more numerous. Their thorax has up to 20 spines on each side in one or two irregular rows although this is usually absent on smaller individuals (under OCL). The spines are generally longer and sharper in southern populations. The tubercles are moderately to densely distributed on specimens over OCL, very sparse to moderately on smaller examples, occasionally absen ...

Euastacus Bidawalus
''Euastacus bidawalus'', the East Gippsland spiny crayfish, is an Australian freshwater crayfish endemic to the East Gippsland area of Victoria (Australia), Victoria and the far south coast of New South Wales. Description The East Gippsland spiny crayfish is similar in overall appearance to other members of the Genus and is morphologically similar to the Euastacus diversus, Orbost Spiny Crayfish ''Euastacus diversus''. Maximum recorded occipital carapace length (OCL) is . The rostrum (anatomy), rostrum is short reaching at most the middle of the third segment of the antenna (biology), antenna, often only to the base of that segment. The Cephalon (arthropod head), cephalon (head) is generally poorly to moderately spined with relatively few spines, of small size or rounded bumps. Sharp spines sometimes found on smaller specimens.

River Blackfish
The river blackfish (''Gadopsis marmoratus'') is a freshwater fish endemic to the temperate waters of south-eastern Australia. It is found from southern Queensland through to central Victoria, including in the Murray- Darling river system. It is also found in some eastern and southern flowing coastal rivers. Found primarily in upland and "midland" habitats, though early records of fish fauna suggest it was originally far more extensively distributed and was found in some lowland habitats as well. Originally, river blackfish co-inhabited many of its lowland and "midland" habitats with species such as Murray cod and golden perch, and its upland habitats with species such as trout cod and Macquarie perch. It is a popular angling fish in some parts of its range. Description River blackfish are elongated with a rounded body, distinct snout and large mouth, and small to moderate sized eyes. The caudal fin, soft dorsal fin and anal fin are rounded. The spiny dorsal fin is low, we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Short-finned Eel
The short-finned eel (''Anguilla australis''), also known as the shortfin eel, is one of the 15 species of eel in the family Anguillidae. It is native to the lakes, dams and coastal rivers of south-eastern Australia, New Zealand, and much of the South Pacific, including New Caledonia, Norfolk Island, Lord Howe Island, Tahiti, and Fiji. Description The body of the adult short-finned eel is long and snakelike, roughly tubular and the head is small, with the jaws reaching back to below the eye or further. The dorsal (top) and anal (bottom) fins are of roughly equal length. The colour varies considerably from one individual to another; a deep olive-green is typical but it can be much lighter; golden or even (rarely) yellowish. There are no markings of note, but the underside is pale, often silvery, and the fins greenish. When full grown, they reach about 90 cm.

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 ...
