Humphry Greenwood
Peter Humphry Greenwood Fellow of the Royal Society, FRS FIBiol (21 April 1927 – 3 March 1995) was an English ichthyologist. Humphry married fellow student Marjorie George (1924 – 2006) in 1950. He was elected a Fellow of the Royal Society in 1985. He was known for his work on the species flocks of cichlids in the African Great Lakes, and for studies of the phylogeny and systematics of teleosts. Tribute The cichlid fish ''Diplotaxodon greenwoodi'' is named for him. Also ''Brachyaetoides greenwoodi'' Bonde, 2008 is named for him. As is ''Enteromius greenwoodi'' (Max Poll, Poll 1967).

Cichlid
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquariu ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uganda

The country is bordered to the east by Kenya, to the north by South Sudan, to the west by the Democratic Republic of the Congo, to the south-west by Rwanda, and to the south by Tanzania. The southern part of the country includes a substantial portion of Lake Victoria, shared with Kenya and Tanzania. Uganda is in the African Great Lakes region. Uganda also lies within the Nile, Nile basin and has a varied but generally a modified equatorial climate. It has a population of around 49 million, of which 8.5 million live in the Capital city, capital and largest city of Kampala.

Lake George (Uganda)
Lake George or Lake Katunguru is a lake in Uganda. It covers a total surface area of and is a part of the African Great Lakes system, although it is not considered one of the Great Lakes. Like the other lakes in the region, it was renamed after a member of the British royal family, in this case Prince George, later to become King George V. Lake George drains to the southwest into Lake Edward through the Kazinga Channel. The area surrounding the lake is populated by the Batooro, Basongora, Banyampaka and Banyankore peoples, among others. All these nations speak closely-related dialects which are generally referred as Runyakitara language. ''Akatunguru'' is a word which means ‘onion’ and is used by all these different peoples. Thus, the lake came to be known as Katunguru because of its onion-like shape. The explorer Henry Morton Stanley was the first European to see the lake in 1875, after following the course of the Katonga River from Lake Victoria during his trans-Africa ...

Kazinga Channel
The Kazinga Channel in Uganda is a wide, long natural channel that links Lake Edward and Lake George (Uganda), Lake George, and a dominant feature of Queen Elizabeth National Park. The channel attracts a varied range of animals and birds, with one of the world's largest concentration of Hippopotamus, hippos and numerous Nile crocodiles. Lake George is a small lake with an average depth of only and which is fed by streams from the Rwenzori mountains. Its outflow is through the Kazinga Channel which drains into Lake Edward, water levels fluctuating very little. In 2005, large numbers of hippos were killed in the channel as a result of an anthrax outbreak, which occurs when animals eat remnants of vegetation in the driest months, absorbing bacterial spores that can live for decades in dry soil. The channel is described as a popular wildlife tourism area. External links Strolling Guides - Kazinga ChannelSome photographs and information. * References Rivers of Ug ...

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplochromis
''Haplochromis'' is a ray-finned fish genus in the family Cichlidae. It has been used as the default "wastebin taxon" for Pseudocrenilabrinae cichlids of the East African Rift, and as such became the "largest" fish "genus". Many of these cichlids are popular aquarium fishes; like similar Haplochromini they are known as "haplos", "happies" or "haps" among aquarium enthusiasts. The genus was established by F.M. Hilgendorf in 1888. It was originally conceived as a subgenus of A.C.L.G. Günther's ''"Chromis"'', at that time an even larger "wastebin genus" for Pseudocrenilabrinae cichlids. The type species of Hilgendorf was '' H. obliquidens''. ''"Chromis"'' of Günther turned out to be a junior homonym of G. Cuvier's ocean fish genus '' Chromis'', already established in 1814, and was abolished. As the years went by, other genera of (mostly) Haplochromini were lumped with and split again from ''Haplochromis'', and the final delimitation of the clade around ''H. obliquidens'' is not ...

Fish Described In 1973
Fish are Aquatic animal, aquatic, craniate, gill-bearing animals that lack Limb (anatomy), limbs with Digit (anatomy), digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, 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 vertebrate, 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 placodermi, external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
