Caenorhabditis Inopinata
''Caenorhabditis inopinata'' - prior to 2017 referred to as ''C. sp. 34.'' - is a sister species to ''C. elegans'' (it is classified in the 'Elegans' supergroup). The specific epithet comes from the Latin inopinus (“unexpected”). This gonochoristic (male-female) species was isolated from figs (''Ficus septica'') and fig wasps in Ishigaki Island, in Japan. It was recovered by N. Kanzaki in 2013. It is a larger species than ''C. elegans''. Its genome is being sequenced at the University of Miyazaki is a national university primarily in the Kibana neighborhood of southern Miyazaki city, Miyazaki Prefecture, Japan. The name is sometimes shortened to the abbreviation "UoM" or the portmanteau "Miyadai." The predecessor of the school was founded ....Kikuchi T., Tsai I., Berriman M., Sugimoto A. and Kanzaki N.

Caenorhabditis Elegans
''Caenorhabditis elegans'' () is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments. It is the type species of its genus. The name is a blend of the Greek ''caeno-'' (recent), ''rhabditis'' (rod-like) and Latin ''elegans'' (elegant). In 1900, Maupas initially named it '' Rhabditides elegans.'' Osche placed it in the subgenus ''Caenorhabditis'' in 1952, and in 1955, Dougherty raised ''Caenorhabditis'' to the status of genus. ''C. elegans'' is an unsegmented pseudocoelomate and lacks respiratory or circulatory systems. Most of these nematodes are hermaphrodites and a few are males. Males have specialised tails for mating that include spicules. In 1963, Sydney Brenner proposed research into ''C. elegans,'' primarily in the area of neuronal development. In 1974, he began research into the molecular and developmental biology of ''C. elegans'', which has since been extensively used as a model organism. It was the first multicellu ...

Gonochorism
In biology, gonochorism is a sexual system where there are only two Sex, sexes and each individual organism is either male or female. The term gonochorism is usually applied in animal species, the vast majority of which are gonochoric. Gonochorism contrasts with Hermaphrodite, simultaneous hermaphroditism but it may be hard to tell if a species is gonochoric or sequentially hermaphroditic. (e.g. Parrotfish, ''Patella ferruginea''). However, in gonochoric species individuals remain either male or female throughout their lives. Species that reproduce by Thelytokous, thelytokous parthenogenesis and do not have males can still be classified as gonochoric. Terminology The term is derived from Greek language, Greek (''gone'', generation) + (''chorizein,'' to separate). The term gonochorism originally came from German gonochorismus. Gonochorism is also referred to as unisexualism or gonochory. Evolution Gonochorism has Convergent evolution, evolved independently multiple time ...

Ficus Septica
''Ficus septica'' (called Hauili in the Philippines, 稜果榕 in Taiwan) is a shrub or tree of the family Moraceae living at low altitudes from northeast India to north Australia (Queensland), and throughout Malesia. It lives on the edge of the vegetation, often in degraded environments. The seeds of this species are dispersed by numerous species, including fruit bats ( Megachiroptera) when present. Taxonomy ''Ficus septica'' was described first by the Dutch botanist Nicolaas Laurens Burman in 1768. Two centuries later, E. J. H. Corner listed three varieties for ''Ficus septica'': ''F. septica'' var. ''septica'' distributed all over the range of the species; ''F. septica'' var. ''cauliflora'' limited to Queensland, Australia and the Solomon islands; and ''F. septica'' var. ''salicifolia'' endemic to the Philippines Islands. Then in the latest Flora Malesiana edition, Cornelis Christiaan Berg put all these varieties in synonymy together under the name ''Ficus septica''. Within t ...

Fig Wasp
Fig wasps are wasps of the superfamily Chalcidoidea which spend their larval stage inside figs. Most are pollinators but others simply feed off the plant. The non-pollinators belong to several groups within the superfamily Chalcidoidea, while the pollinators are in the family Agaonidae. While pollinating fig wasps are gall-makers, the remaining types either make their own galls or usurp the galls of other fig wasps; reports of their being parasitoids are considered dubious. History Aristotle recorded in his ''History of Animals'' that the fruits of the wild fig (the caprifig) contain ''psenes'' (fig wasps); these begin life as grubs (larvae), and the adult ''psen'' splits its "skin" (pupa) and flies out of the fig to find and enter a cultivated fig, saving it from dropping. He believed that the ''psen'' was generated spontaneously; he did not recognise that the fig was reproducing sexually and that the ''psen'' was assisting in that process. Taxonomy The fig wasps are a pol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ishigaki Island
, also known as ''Ishigakijima'', is a Japanese island south-west of Okinawa Hontō and the second-largest island of the Yaeyama Island group, behind Iriomote Island. It is located approximately south-west of Okinawa Hontō. It is within the City of Ishigaki in Okinawa Prefecture. The city functions as the business and transport center of the archipelago. The island is served by New Ishigaki Airport, the largest airport in the Yaeyamas. Much of the island and surrounding waters including Mount Omoto and Kabira Bay are protected as part of Iriomote-Ishigaki National Park. Ishigaki Island, like the rest of Okinawa, is culturally influenced by both Japan and Taiwan due to its location, about off the north eastern coast of Taiwan. History A tsunami of record height hit Ishigaki Island in 1771. One of the perpetrators of Aum Shinrikyo's sarin gas attack, Yasuo Hayashi, was arrested on Ishigaki Island 21 months after the attacks and from the scene of the crime. Ishigak ...

Elegans Supergroup
This list of Latin and Greek words commonly used in systematic names is intended to help those unfamiliar with classical languages to understand and remember the scientific names of organisms. The binomial nomenclature used for animals and plants is largely derived from Latin and Greek words, as are some of the names used for higher taxa, such as orders and above. At the time when biologist Carl Linnaeus (1707–1778) published the books that are now accepted as the starting point of binomial nomenclature, Latin was used in Western Europe as the common language of science, and scientific names were in Latin or Greek: Linnaeus continued this practice. Although Latin is now largely unused except by classical scholars, or for certain purposes in botany, medicine and the Roman Catholic Church, it can still be found in scientific names. It is helpful to be able to understand the source of scientific names. Although the Latin names do not always correspond to the current English common n ...

Nematodes Described In 2013
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over time.
