Neolamprologus Meeli
''Lepidiolamprologus meeli'' is a cichlid species in the subfamily Pseudocrenilabrinae. It is endemic to Lake Tanganyika, where it is found in the waters of Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia. It is sometimes placed in ''Neolamprologus'', and this may well be appropriate. As it seems, it belongs to a group also including '' N. boulengeri'' and '' L. hecqui'', '' L. attenuatus'' and '' L. kendalli''. Abstract Etymology This cichlid is named in honor of botanist Ludo van Meel (1908-1990), a member of the Belgian Hydrobiological Mission to Lake Tanganyika that took place between 1946 and 1947, during which the type specimen was collected. Hybrids As hybridization seems to have played a major role in the radiation of this group, the exact relationships of the present species are obscure; one specimens was found to belong to an mtDNA lineage quite similar to ''L./N. hecqui'', while another was distantly similar to ''L. kendalli'' in this regard.

Max Poll
Max Fernand Leon Poll (21 July 1908 in Ruisbroek, Flemish Brabant, Ruisbroek – 13 March 1991 in Uccle) was a Belgians, Belgian ichthyologist who specialised in the Cichlidae. In the years 1946 and 1947 he organised an exploration, 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 Université Libre de Bruxelles, and Conservator (museum), conservator at Musée Royal du Congo Belge in Tervuren.

Lepidiolamprologus Attenuatus
''Lepidiolamprologus attenuatus'' is a species of cichlid endemic to Lake Tanganyika preferring areas with sandy substrates in which it digs crater-shaped nests. This species is carnivorous preying on fishes. This species can reach a length of TL. It can also be found in the aquarium An aquarium (plural: ''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.

Fish Described In 1949
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Taxa Named By Max Poll
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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidiolamprologus
''Lepidiolamprologus'' is a small genus of cichlids endemic to Lake Tanganyika in eastern Africa. It is closely related to ''Altolamprologus.'' and there is the possibility that a revision of the genus could see more species added. The placement of '' L. cunningtoni'' has been questioned, as it seems to be a close relative of '' N. modestus'' and the Fourspine Cichlid (''N. tetracanthus''), though with hybridization running rampant in the Lamprologini, one cannot entirely be sure of its relationships at present. However it differs enough from the other species in ''Lepidiolamprologus'' to conclude that it may not belong in this genus.

DNA Sequence
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid speed of sequencing attained with modern D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

MtDNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived from t ...

Radiation (evolution)
In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches. Starting with a single ancestor, this process results in the speciation and phenotypic adaptation of an array of species exhibiting different morphological and physiological traits. The prototypical example of adaptive radiation is finch speciation on the Galapagos ("Darwin's finches"), but examples are known from around the world. Characteristics Four features can be used to identify an adaptive radiation: #A common ancestry of component species: specifically a ''recent'' ancestry. Note that this is not the same as a monophyly in which ''all'' descendants of a common ancestor are included. #A phenotype-environment correlation: a ''significant'' association between environments and the morp ...

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] |
Ludo Van Meel
Ludo (; ) is a strategy board game for two to four players, in which the players race their four from start to finish according to the rolls of a single die. Like other cross and circle games, Ludo is derived from the Indian game Pachisi. The game and its variations are popular in many countries and under various names. History The Mahabharata Pachisi was created in India in the sixth century CE. The earliest evidence of this game's evolution in India is the depiction of boards on the caves of Ellora. The original version is also described in the Indian epic Mahabharata in which Shakuni uses cursed dice to beat the Pandavas, and at last after losing everything, Yudhisthira puts his wife Draupadi on stake and loses her, too. The Pandavas get all their belongings back, though, after Draupadi vows to curse the whole Kuru lineage, but stops at the intervention of Gandhari, and seeing an opportunity to still Draupadi's anger, Kuru king Dhritarashtra promises to give back ...
