Running River Rainbowfish
The Running River rainbowfish (''Melanotaenia'' sp., also known as the Burdekin rainbowfish, Hidden Valley rainbowfish or zig zag rainbowfish) is an undescribed species of rainbowfish found only in Running River, part of the Burdekin River catchment in northern Queensland, Australia. Taxonomy Although discovered in 1982 by Ray Leggett,Unmack PJ (2016) ''Fishes of Sahul'', 30(3): 1025–1032 (September 2016) the species was never formally described as its taxonomy was unclear.Unmack PJ and Hammer MP (2015) ''Fishes of Sahul'', 29(4): 933–936 (December 2015) However, genetic analysis supports the Running River rainbowfish as a distinct species, rather than a colour variety of the eastern rainbowfish. Conservation In the wild, the Running River rainbowfish is confined to a 13 km stretch of Running River, isolated between two gorges. In August 2015, ecologists Peter Unmack and Michael Hammer discovered that eastern rainbowfish had been introduced into the upper section of Ru ...

Rainbowfish
The rainbowfish or Melanotaeniidae is a family of small, colourful freshwater fish found in northern and eastern Australia, New Guinea (including islands in Cenderawasih Bay and Raja Ampat Islands in Indonesia), Sulawesi and Madagascar. The largest rainbowfish genus, ''Melanotaenia'', derives from the ancient Greek ''melano'' (black) and ''taenia'' (banded). Translated, it means "black-banded", and is a reference to the often striking lateral black bands that run along the bodies of those in the genus ''Melanotaenia''. Characteristics The Melanotaeniidae is characterised by having their distal premaxillary teeth enlarged. They have a compressed body with the two dorsal fins being separated but with only a small gap between them. There are 3–7 spines in the first dorsal fin while the second has 6–22 rays, with the first ray being a stout spine in some species, the anal fin has 10–30 rays and, again, the first may be a stout spine in some species. The lateral line is either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burdekin River
The Burdekin River is a river located in North and Far North Queensland, Australia. The river rises on the northern slopes of Boulder Mountain at Valley of Lagoons, part of the western slope of the Seaview Range, and flows into the Coral Sea at Upstart Bay over to the southeast of the source, with a catchment area of approximately . The Burdekin River is Australia's largest river by (peak) discharge volume. The river was first encountered by Europeans during the expedition led by Ludwig Leichhardt in 1845 and named in honour of Thomas Burdekin, one of the sponsors of the expedition. Course and features The Burdekin River rises on the western slopes of the Seaview Range, part of the Great Dividing Range, west of . In the river's upper catchment, from its source the river generally flows west and then south out of the Girringun National Park, part of the UNESCO Wet Tropics World Heritage Area. This area, now part of Basalt was the location of one of the earliest inland settleme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern Rainbowfish
''Melanotaenia splendida splendida'', also known as the eastern rainbowfish, is a subspecies of fish in the family Melanotaeniidae endemic to Australia. The Eastern rainbowfish is widespread on the mainland, and is found in river systems east of the Great Dividing Range of Queensland, Australia, from the Boyne River south of Gladstone to Cape York Peninsula. It is usually found in large schools inhabiting small freshwater streams, but is also found in lakes and reservoirs. It is kept as a tropical aquarium fish. Description and diet It is a small fish commonly found up to 8 cm but known to reach up to 14 cm. Males are highly variable in colour from pale bluish-green or greenish-brown overall to yellowish and paler below, with a yellow or orange spot on the gill cover. Females and juveniles are silvery with translucent or faintly coloured fins. The Eastern rainbowfish is an omnivore and feeds on algae, insects, microcrustaceans and other small invertebrate Inve ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Introgression
Introgression, also known as introgressive hybridization, in genetics is the transfer of genetic material from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species. Introgression is a long-term process, even when artificial; it may take many hybrid generations before significant backcrossing occurs. This process is distinct from most forms of gene flow in that it occurs between two populations of different species, rather than two populations of the same species. Introgression also differs from simple hybridization. Simple hybridization results in a relatively even mixture; gene and allele frequencies in the first generation will be a uniform mix of two parental species, such as that observed in mules. Introgression, on the other hand, results in a complex, highly variable mixture of genes, and may only involve a minimal percentage of the donor genome.

Freshwater Fish Of Queensland
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water i ...
