Indostomus Crocodilus Narathiwat
''Indostomus'' is a genus of small fishes native to slow moving or stagnant freshwater habitats in Indochina. It is the sole genus of the monogeneric family Indostomidae, Long considered to be sticklebacks, within the order Gasterosteiformes, modern analyses place the Indostomids within the order Synbranchiformes, related to the spiny eels and swamp eels. Taxonomy ''Indostomus'' was first proposed as a genus in 1929 by the Indian zoologists Baini Prashad and Dev Dev Mukerji when they described ''Indostomus paradoxus'', giving its type locality as north of the Indawgyi Lake near Nyaungbin in Upper Burma. As the same time they also classified this new genus in the new monotypic family Indostomidae. Indostomidae was classified within the order Gasterostiformes, placed in the suborder Gasterosteoidei. Phylogenetics have, however, shown that Gasterostiformes was paraphyletic with the Gasterosteoidei not being sister to the Syngnathoidei and being more closely related to the Zoarc ...

Baini Prashad
Baini Prashad Order of the British Empire, OBE Fellow of the Royal Society of Edinburgh, FRSE (13 March 1894 – 18 January 1969) was an Indian zoologist who specialized chiefly in malacology and ichthyology. He served as the first Indian director of the Zoological Survey of India, succeeding R. B. Seymour Sewell, R.B.S. Sewell. He was also a scholar of Persian and took an interest in the history of zoology. Prashad was born at Kartarpur, India, Kirtarpur to ''Rai Sahib'' Devi Das, who was an administrative officer in the government in Punjab. His paternal grandfather ''Rai Sahib'' Gopal Das had been a commissioner. Prashad studied in Lahore and graduated from the Government College in Lahore in 1913 followed by a MSc in 1914. He worked on a Ph.D. under John Stephenson (zoologist), J. Stephenson, a specialist on annelids and professor of Zoology and was the first person to receive a non-honorary D.Sc. degree from Punjab University in 1918. His research was on the calciferous glands o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Burma
Upper Myanmar ( my, အထက်မြန်မာပြည်, also called Upper Burma) is a geographic region of Myanmar, traditionally encompassing Mandalay and its periphery (modern Mandalay, Sagaing, Magway Regions), or more broadly speaking, Kachin and Shan States. In the Burmese language, people originating from Upper Myanmar are typically called ''a-nya tha'' (), whereas those from Lower Myanmar are called ''auk tha'' (). The term "upper Burma" was first used by the British to refer to the central and northern area of what is now modern day Myanmar. After the Second Anglo-Burmese War of 1852, Lower Myanmar was annexed by the British Empire, while Upper Myanmar remained independent under the Burmese Empire until the Third Anglo-Burmese War of 1885. Upper Myanmar was also known as encompassing "Burma proper" and the Kingdom of Ava. Historically, Upper Myanmar was predominantly Bamar (whereas Lower Myanmar was historically Mon-speaking until the early 19th century), ...

Gourami
Gouramis, or gouramies , are a group of freshwater anabantiform fishes that comprise the family Osphronemidae. The fish are native to Asia—from the Indian Subcontinent to Southeast Asia and northeasterly towards Korea. The name "gourami", of Indonesian origin, is also used for fish of the families Helostomatidae and Anabantidae. Many gouramis have an elongated, feeler-like ray at the front of each of their pelvic fins. All living species show parental care until fry are free swimming: some are mouthbrooders, like the Krabi mouth-brooding betta (''Betta Simplex''), and others, like the Siamese fighting fish (''Betta splendens''), build bubble nests. Currently, about 133 species are recognised, placed in four subfamilies and about 15 genera. The name Polyacanthidae has also been used for this family. Some fish now classified as gouramis were previously placed in family Anabantidae. The subfamily Belontiinae was recently demoted from the family Belontiidae. As labyrinth fishe ...

Blackwater River
A blackwater river is a type of river with a slow-moving channel flowing through forested swamps or wetlands. As vegetation decays, tannins leach into the water, making a transparent, acidic water that is darkly stained, resembling black tea. Most major blackwater rivers are in the Amazon Basin and the Southern United States. The term is used in fluvial studies, geology, geography, ecology, and biology. Not all dark rivers are blackwater in that technical sense. Some rivers in temperate regions, which drain or flow through areas of dark black loam, are simply black due to the color of the soil; these rivers are ''black mud rivers''. There are also black mud estuaries. Blackwater rivers are lower in nutrients than whitewater rivers and have ionic concentrations higher than rainwater. The unique conditions lead to flora and fauna that differ from both whitewater and clearwater rivers. The classification of Amazonian rivers into black, clear, and whitewater was fir ...

Oxbow Lake
An oxbow lake is a U-shaped lake or pool that forms when a wide meander of a river is cut off, creating a free-standing body of water. In South Texas, oxbows left by the Rio Grande are called '' resacas''. In Australia, oxbow lakes are called billabongs. The word "oxbow" can also refer to a U-shaped bend in a river or stream, whether or not it is cut off from the main stream. Geology An oxbow lake forms when a meandering river erodes through the neck of one of its meanders. This takes place because meanders tend to grow and become more curved over time. The river then follows a shorter course that bypasses the meander. The entrances to the abandoned meander eventually silt up, forming an oxbow lake. Because oxbow lakes are stillwater lakes, with no current flowing through them, the entire lake gradually silts up, becoming a bog or swamp and then evaporating completely. When a river reaches a low-lying plain, often in its final course to the sea or a lake, it meanders wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Syngnathoidei
The Syngnathiformes are an order of ray-finned fishes that includes the trumpetfishes and seahorses.FishBase (2005)Order Summary for Syngnathiformes Version of 2005-FEB-15. Retrieved 19 Aug 2008. These fishes have elongated, narrow, bodies surrounded by a series of bony rings, and small, tubular mouths. The shape of their mouth—in at least syngnathids—allows for the ingestion of prey at close range via suction. Several groups of Syngnathiformes live among seaweed and swim with their bodies aligned vertically, to blend in with the stems. The most defining characteristic of this order is their reverse sexual system. In this order, males conduct in specialized brooding and rearing of the embryos. The males house eggs in an osmoregulated pouch or adhere eggs to their tail until the eggs reach maturity. The name Syngnathiformes means "conjoined-jaws". It is derived from Ancient Greek ''syn'' (συν, "together") + ''gnathos'' (γνάθος, "jaw"). The ending for fish orders "-f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sister Group
In phylogenetics, a sister group or sister taxon, also called an adelphotaxon, comprises the closest relative(s) of another given unit in an evolutionary tree. Definition The expression is most easily illustrated by a cladogram: Taxon A and taxon B are sister groups to each other. Taxa A and B, together with any other extant or extinct descendants of their most recent common ancestor (MRCA), form a monophyletic group, the clade AB. Clade AB and taxon C are also sister groups. Taxa A, B, and C, together with all other descendants of their MRCA form the clade ABC. The whole clade ABC is itself a subtree of a larger tree which offers yet more sister group relationships, both among the leaves and among larger, more deeply rooted clades. The tree structure shown connects through its root to the rest of the universal tree of life. In cladistic standards, taxa A, B, and C may represent specimens, species, genera, or any other taxonomic units. If A and B are at the same taxonomic ...

Paraphyletic
In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of Synapomorphy and apomorphy, synapomorphies and symplesiomorphy, symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia (reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenetics
In biology, phylogenetics (; from Greek language, Greek wikt:φυλή, φυλή/wikt:φῦλον, φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, Protein, protein Amino acid, amino acid sequences, or Morphology (biology), morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
