Chalinochromis Popelini
''Chalinochromis'' is a small cichlid genus from the subfamily Pseudocrenilabrinae. These ray-finned fishes are endemic to Lake Tanganyika in the East African Rift. The scientific name refers to the bridle-like markings across the heads of members of this genus. They have specialized jaws enabling them to feed on sponges. (2007): Phylogenetic relationships of the Lake Tanganyika cichlid tribe Lamprologini: The story from mitochondrial DNA. '' Mol. Phylogenet. Evol.'' 45(2): 629–642. (HTML abstract) This genus has a puzzling relationship with the extremely similar species placed in ''Julidochromis''. In their mtDNA NADH dehydrogenase subunit 2 sequence, ''Chalinochromis'' are closer to '' J. dickfeldi'', '' J. ornatus'' and '' J. transcriptus'' – in particular the latter two – than to any other living fish, while '' J. marlieri'' and '' J. regani'' are closer to ''Telmatochromis''. ''Julidochromis'' thus might need to be split in two, with ''Chalinochromis'' include ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Max Poll
Max Fernand Leon Poll (21 July 1908 in Ruisbroek – 13 March 1991 in Uccle) was a Belgian ichthyologist who specialised in the Cichlidae. In the years 1946 and 1947 he organised an expedition to Lake Tanganyika. He has described several species of Pseudocrenilabrinae, such as '' Lamprologus signatus'', '' Steatocranus casuarius'', '' Neolamprologus brichardi'', and '' Neolamprologus pulcher''. He was a member of The Royal Academies for Science and the Arts of Belgium, professor at the Université libre de Bruxelles, and conservator at the Royal Museum of the Belgian Congo in Tervuren. He was an honorary member of the American Society of Ichthyologists and Herpetologists. Taxon named in his honor Named after him are species and taxa In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit.

Julidochromis Dickfeldi
''Julidochromis dickfeldi'' is a species of cichlid endemic to Lake Tanganyika in Africa where it is only known from the southwestern portion. This species inhabits areas with rock/rubble substrates, each fish maintaining a territory around a crevice or crack. This species reaches a length of TL. Etymology The specific name honours the German fishkeeper Alf Dickfeld who proposed the expedition on which the type was collected.

Sven O
Sven is a Scandinavian masculine first name. In Old Norse the meaning was "young man" or "servant" and the original Old Norse spelling was ''sveinn''. Variants such as '' Svend'' are found in Danish and Norwegian. Another variant, '' Svein'' is used only in the Low Countries and German-speaking countries, and is cognate with the English surname '' Swain''. In medieval Swedish, ''sven'' or ''sven av vapen'' "sven of arms", is a term for squire. The female equivalent, Svenja, though seemingly Dutch and Scandinavian, is not common anywhere outside of German-speaking countries. Sven can also be spelled with a "w" - Swen - but is pronounced as Sven. The Icelandic version is ''Sveinn'' (); the Faroese version is Sveinur ().

Chalinochromis Brichardi
''Chalinochromis brichardi'' is a species of fish in the family Cichlidae. It is found in Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia. It is endemic to Lake Tanganyika. It builds a nest of rubble which is hidden by plants or algae, and its diet consists primarily of invertebrates. The specific name of this fish honours the fish dealer Pierre Brichard (1921-1990), who was the collector of the type Type may refer to: Science and technology Computing * Typing, producing text via a keyboard, typewriter, etc. * Data type, collection of values used for computations. * File type * TYPE (DOS command), a command to display contents of a file. * .... Description Adult specimens average a length of approximately 8.9 cm (3.5 inches), but larger specimens up to 14 cm (5.5 inches) have been recorded in captivity. ''C. brichardi'' lacks any body striping as an adult, only possessing barring around the facial region, which differentiates it from other ''Chalinochromi ...

Lamprologini
Lamprologini is a tribe of African cichlid fishes. It contains seven genera and nearly 100 species. Over half of the species in this tribe are in the large genus ''Neolamprologus''. Most genera in the tribe are endemic to Lake Tanganyika, but one species of ''Neolamprologus'' ('' N. devosi'') is from the Malagarasi River in Tanzania, and several species of '' Lamprologus'' are from the Congo River Basin. The species in this tribe are very small to medium-sized cichlids, but vary extensively in appearance and habitat preference.Smith, M.P. (1998). Lake Tanganyikan Cichlids, p. 10—11. Unlike most Tanganyika cichlids which are mouthbrooders, Lamprologini species are substrate spawners (typically using caves or rock crevices), and some are shell dwellers.

Aquarium
An aquarium (: aquariums or aquaria) is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. fishkeeping, Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles, such as turtles, and aquatic plants. The term ''aquarium'', coined by English naturalist Philip Henry Gosse, combines the Latin root , meaning 'water', with the suffix , meaning 'a place for relating to'. The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian era, Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'' in 1854.

Monophyletic
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A '' polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate 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 hybridization, which include genetic and morph ...

Telmatochromis
__NOTOC__ ''Telmatochromis'' is a small cichlid genus of the subfamily Pseudocrenilabrinae. These ray-finned fishes are endemic to the Lake Tanganyika basin (mostly in the lake itself, but also its outflow river Lukuga) in Africa. Systematics Analysis of their mtDNA NADH dehydrogenase subunit 2 (ND2) sequence shows that hybridization must have played some role in the evolution of this genus. (2007): Phylogenetic relationships of the Lake Tanganyika cichlid tribe Lamprologini: The story from mitochondrial DNA. '' Mol. Phylogenet. Evol.'' 45(2): 629–642. (HTML abstract) For one thing, it might be that ''Telmatochromis'' is close to ''Julidochromis'', which they somewhat resemble. A possibility is hybridization between the ancestor of ''Telmatochromis'' and a lineage of ''Julidochromis'' which later gave rise to '' J. marlieri'' and the Convict Julie (''J. regani''). Similar ND2 DNA has been found in these and '' T. bifrenatus'', '' T. brichardi'' and '' T. temporalis''. '' T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julidochromis Regani
The convict julie (''Julidochromis regani'') is a cichlid species in the subfamily Pseudocrenilabrinae family endemic to Lake Tanganyika. Hence it is found in Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia. The fish is named after Charles Tate Regan. This species is closely related to ''Julidochromis marlieri''. Possibly, a male common ancestor of these two hybrid (biology), hybridised with some female ''Telmatochromis'' ancestor in their evolutionary past.
