Caenorhabditis Drosophilae
''Caenorhabditis drosophilae'' is a species of nematodes. It was recovered, along with '' Rhabditis sonorae'', from saguaro cactus rot in Arizona. The species was found on the fly ''Drosophila nigrospiracula''. ''C. drosophilae'' forms a ''Drosophilae supergroup'' with other ''Caenorhabditis'' species ('' C. virilis'', '' C. castelli'', '' C. angaria''). This supergroup gathers species associated with rotten cactus or fruit and '' Drosophila'' species. It opposes the ''elegans'' supergroup where ''C. 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'' (r ...'' stands.

Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-Parasitism, 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 Arthropod, arthropods, Tardigrade, tardigrades and other moulting animalia, animals in the clade Ecdysozoa, and unlike platyhelminthe, flatworms, have tubular digestion, 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 ...

Saguaro Cactus
The saguaro (, ) (''Carnegiea gigantea'') is a tree-like cactus species in the monotypic genus ''Carnegiea'' that can grow to be over tall. It is native to the Sonoran Desert in Arizona, the Mexican state of Sonora, and the Whipple Mountains and Imperial County areas of California. The saguaro blossom is the state wildflower of Arizona. Its scientific name is given in honor of Andrew Carnegie. In 1994, Saguaro National Park, near Tucson, Arizona, was designated to help protect this species and its habitat. Saguaros have a relatively long lifespan, often exceeding 150 years. They may grow their first side arm around 75–100 years of age, but some never grow any arms. Arms are developed to increase the plant's reproductive capacity, as more apices lead to more flowers and fruit. A saguaro can absorb and store considerable amounts of rainwater, visibly expanding in the process, while slowly using the stored water as needed. This characteristic enables the saguaro t ...

Drosophila Nigrospiracula
''Drosophila nigrospiracula'' is a fly species indigenous to the Sonoran Desert, spanning Arizona, Baja California, and part of Sonora, Mexico. ''D. nigrospiracula'' share the Sonoran Desert with three other species of ''Drosophila'': ''D. pachea, Drosophila mettleri, D. mettleri'', and ''Drosophila mojavensis, D. mojavensis''. This fly breeds on the decomposing tissues of two species of cacti that are also endemic to the region: Cardon cactus, cardón ''(Pachycereus pringlei)'' and saguaro ''(Carnegiea gigantea).'' Taxonomy ''D. nigrospiracula'' is part of the ''D. anceps'' species complex. This species is categorized as part of the ''D. mulleri'' subgroup, one of the five subgroups within the ''Drosophila repleta'' group of the ''Drosophila'' genus. The four ''Drosophila'' fly species inhabiting the Sonoran Desert are not particularly closely related to each other but are all, however, under the repleta group. Each species came to inhabit this region independently, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caenorhabditis Angaria
''Caenorhabditis angaria'' is a small nematode, in the same genus as the model organism ''Caenorhabditis elegans''. The name is from the Latin (''angarius'' "mounted courier") after the tendency to ride weevils. Prior to 2011, the species was referred to as ''C. sp. 2'', ''C. sp. 3'', and ''C. sp. PS1010''. Its genome was sequenced at the California Institute of Technology in 2010. This species is gonochoristic. It has distinct morphology and behavior compared to ''C. elegans''; notably, ''C. angaria'' males exhibit a spiral mating behavior. Its divergence from ''C. elegans'' is similar to the distance between humans and fish. ''C. castelli'' is its closest relative, and the two species can produce F1 hybrids. ''C. angaria'' was isolated in Trinidad and Florida, found in association with palm and sugarcane weevils, ''Rhynchophorus palmarum The South American palm weevil, ''Rhynchophorus palmarum'', is a species of snout beetle. The adults are relatively large black beetles of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drosophila
''Drosophila'' () is a genus of flies, belonging to the family Drosophilidae, whose members are often called "small fruit flies" or (less frequently) pomace flies, vinegar flies, or wine flies, a reference to the characteristic of many species to linger around overripe or rotting fruit. They should not be confused with the Tephritidae, a related family, which are also called fruit flies (sometimes referred to as "true fruit flies"); tephritids feed primarily on unripe or ripe fruit, with many species being regarded as destructive agricultural pests, especially the Mediterranean fruit fly. One species of ''Drosophila'' in particular, ''D. melanogaster'', has been heavily used in research in genetics and is a common model organism in developmental biology. The terms "fruit fly" and "''Drosophila''" are often used synonymously with ''D. melanogaster'' in modern biological literature. The entire genus, however, contains more than 1,500 species and is very diverse in appearance, be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Drosophilae Supergroup
''Caenorhabditis'' is a genus of nematodes which live in bacteria-rich environments like compost piles, decaying dead animals and rotting fruit. The name comes from Greek: caeno- (καινός (caenos) = new, recent); rhabditis = rod-like (ῥάβδος (rhabdos) = rod, wand). In 1900, Maupas initially named the species ''Rhabditis elegans'', Osche placed it in the subgenus ''Caenorhabditis'' in 1952, and in 1955, Dougherty raised ''Caenorhabditis'' to the status of genus. The genus ''Caenorhabditis'' contains the noted model organism ''Caenorhabditis elegans'' and several other species for which a genome sequence is either available or currently being determined. The two most-studied species in this genus (''C. elegans'' and ''C. briggsae'') are both androdioecious (they have male and hermaphrodite sexes) whereas most other species are gonochoristic (they have male and female sexes). ''C. elegans'' is the type species of the genus. Ecology ''Caenorhabditis'' occupy various n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural History Of Arizona
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe, is one of several expansions of the original notion; it began with certain core applications of the word φύσις by pre-Socr ...
