Squalius
''Squalius'' is a genus of fish in the family Cyprinidae found in Europe and Asia. Hybridization is not rare in the Cyprinidae, including this genus. '' S. alburnoides'' is known to be of ancient hybrid origin, with the paternal lineage deriving from a prehistoric species related to ''Anaecypris''; the latter mated with ancestral '' S. pyrenaicus''. Present-day ''S. alburnoides'' mates with sympatric congeners of other species.Collares-Pereira, M.J. & Coelho, M.M.

Squalius Alburnoides
''Squalius alburnoides'' is a species of fish in the family Cyprinidae. It is found in Portugal and Spain. Its natural habitats are rivers and intermittent rivers. It may be threatened by habitat loss. This species is a highly peculiar fish in regard to its evolution and reproduction. It has been derived from hybridisation between females of ''Squalius pyrenaicus'' and males of another, unknown cyprinid species, and maintains the genomes of both parental species. ''Squalius alburnoides'' may have various numbers of these genomes (polyploidy), and may use different reproductive modes to pass them on to the offspring, including asexual reproduction, normal meiosis and hybridogenesis. It has the first confirmed instance of natural androgenesis Androgenesis occurs when a zygote is produced with only paternal nuclear genes. During standard sexual reproduction, one female and one male parent each produce haploid gametes(such as a sperm or egg cell, each containing only a single set ...

Squalius Aradensis
''Squalius aradensis'' is a ray-finned fish species in the family Cyprinidae, growing to SL. It is endemic to Portugal where it is found in only three river basins: Arade The Arade () is a river located in the region of the Algarve, southern Portugal. the river's course takes it through the municipalities of Silves, Lagoa and Portimão. The source of the river lies to the southwest of the Serra do Caldeirão mou ..., Algibre, and Bordeira basins. It is threatened by water extraction, drought, and introduction of exotic fish species. ''Squalius aradensis'' is an ubiquitous species which inhabits small to medium-sized streams with Mediterranean water regime. It may be restricted to very small pools during summer. It breeds in shallow riffle habitats in fast-flowing water.

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

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] |
