Drosophila Musaphilia
''Drosophila musaphilia'' is an endangered species of fly from Hawaii, in the species rich lineage of Hawaiian Drosophilidae. It is only found on the island of Kauai. The last reported sighting of this species was in 1988. Description ''Drosophila musaphilia'' was described in 1965 by D. Elmo Hardy. The species name is in reference to the fact that this species, like many other picture-wing ''Drosophila'', is strongly attracted to the smell of rotting banana. This species is a member of the ''hawaiiensis'' subgroup in the picture-wing clade. ''D. musaphilia'' flies are mostly black, with gray hairs along the thorax. The wing markings are similar to other closely related species in the subgroup, with a stripe of spots along the center and apex of the wing. ''D. musaphilia'' females have the second longest ovipositor recorded from species of Hawaiian ''Drosophila'', second to '' D. orphnopeza,'' with both species measuring at >1 millimeter. Rearing records for this species ind ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected ...

Hawaiian Drosophilidae
The Hawaiian Drosophilidae are a lineage of flies within the genus ''Drosophila.'' This monophyletic clade includes all of the endemic Hawaiian ''Drosophila'' and all members of the genus '' Scaptomyza'', which contains both Hawaiian and non-Hawaiian species. The Hawaiian Drosophilidae are descended from a common ancestor estimated to have lived 25 million years ago. Species of Hawaiian Drosophilidae flies have been studied as models of speciation and behavioral evolution. Along with other members of the native Hawaiian ecosystem, the conservations status of many species of Hawaiian Drosophilidae is threatened by habitat loss and introduced predators, among other factors. Diversity There are an estimated 1,000 species of Hawaiian Drosophilidae. 689 species have been described, including 273 species in the genus '' Scaptomyza'', of which 148 are endemic to the Hawaiian archipelago, and 416 Hawaiian endemic species in the genus ''Drosophila.''

Kauai
Kauai, () anglicized as Kauai ( ), is geologically the second-oldest of the main Hawaiian Islands (after Niʻihau). With an area of 562.3 square miles (1,456.4 km2), it is the fourth-largest of these islands and the 21st largest island in the United States. Nicknamed the Garden Isle, Kauai lies 73 miles (117 km) across the Kauai Channel, northwest of Oahu. This island is the site of Waimea Canyon State Park and the Na Pali Coast State Park. The United States Census Bureau defines Kauai as census tracts 401 through 409 of Kauai County, Hawaii, which comprises all of the county except the islands of Kaʻula, Lehua and Niihau. The 2020 United States census population of the island was 73,298. The most populous town is Kapaa. Etymology and language Hawaiian narrative locates the name's origin in the legend of Hawaiiloa, the Polynesian navigator credited with discovery of the Hawaiian Islands. The story relates how he named the island of Kauai after a favorite son; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ovipositor
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs. In insects, an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as preparing a place for the egg, transmitting the egg, and then placing it properly. For most insects, the organ is used merely to attach the egg to some surface, but for many parasitic species (primarily in wasps and other Hymenoptera), it is a piercing organ as well. Some ovipositors only retract partly when not in use, and the basal part that sticks out is known as the scape, or more specifically oviscape, the word ''scape'' deriving from the Latin word '' scāpus'', meaning "stalk" or "shaft". In insects Grasshoppers use their ovipositors to force a burrow into the earth to receive the eggs. Cicadas pierce the wood of twigs with their ovipositors to insert the eggs. Sawflies slit the ...

Drosophila Orphnopeza
''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, beha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acacia Koa
''Acacia koa'' or commonly known as koa is a species of flowering tree in the family Fabaceae. It is endemic to the Hawaiian Islands, where it is the second most common tree. The highest populations are on Hawaii, Maui and Oahu. Name The name ''koa'' in the Hawaiian language ultimately comes from Proto-Austronesian *''teRas'' meaning "core" or "ironwood"; many names referring to certain ironwood or heartwood species in Southeast Asia and Oceania such as ''Vitex parviflora'' (''tugás'' in Cebuano), ''Eusideroxylon zwageri'' (''togas'' in Tombonuwo), and ''Intsia bijuga'' (''dort'' in Palauan) descend from this root. ''Koa'' also means brave, bold, fearless, or warrior. Description Koa is a large tree, typically attaining a height of and a spread of . In deep volcanic ash, a koa tree can reach a height of , a circumference of , and a spread of . It is one of the fastest-growing Hawaiian trees, capable of reaching in five years on a good site.

Psidium Cattleyanum
''Psidium cattleyanum (World Plants : Psidium cattleianum)'', commonly known as Cattley guava, strawberry guava or cherry guava, is a small tree (2–6 m tall) in the Myrtaceae (myrtle) family. The species is named in honour of English horticulturist William Cattley. Its genus name ''Psidium'' comes from the Latin ''psidion'', or "armlet." The red-fruited variety, ''P. cattleyanum var. cattleyanum'', is commonly known as purple guava, red cattley guava, red strawberry guava and red cherry guava. The yellow-fruited variety, ''P. cattleyanum var. littorale'' is variously known as yellow cattley guava, yellow strawberry guava, yellow cherry guava, lemon guava and in Hawaii as ''waiawī''.

Black-tailed Deer
Two forms of black-tailed deer or blacktail deer that occupy coastal woodlands in the Pacific Northwest of North America are subspecies of the mule deer (''Odocoileus hemionus''). They have sometimes been treated as a species, but virtually all recent authorities maintain they are subspecies.Novak, R. M. (1999). ''Walker's Mammals of the World.'' 6th edition. Heffelfinger, J.

Lantana Camara
''Lantana camara'' (common lantana) is a species of flowering plant within the verbena family (Verbenaceae), native to the American tropics. It is a very adaptable species, which can inhabit a wide variety of ecosystems; once it has been introduced into a habitat it spreads rapidly; between 45ºN and 45ºS and more than in altitude. It has spread from its native range to around 50 countries, where it has become an invasive species. It first spread out of the Americas when it was brought to Europe by Dutch explorers and cultivated widely, soon spreading further into Asia and Oceania where it has established itself as a notorious weed, and in Goa it was introduced by the Portuguese. ''L. camara'' can outcompete native speci leading to a reduction in biodiversity. It can also cause problems if it invades agricultural areas as a result of its toxicity to livestock, as well as its ability to form dense thickets which, if left unchecked, can greatly reduce the Agricultural productivi ...

Melinis Minutiflora
''Melinis minutiflora'', commonly known as molasses grass, is a species of grass. It is a perennial grass native to Africa, where it occurs in disjunct populations (an arc from central Angola to Cameroon in western central africa, the areas around Ruwenzori Mountains and Mount Kenya in eastern Africa. Its seeds are dispersed by wind. Molasses grass usually grows to be thirty to sixty inches tall, and it forms mats when its long, slender stems lay on top of each other in layers up to four feet deep. Molasses grass can spread up other plants, using them as support, like a vine. It has fragrant foliage and colorful inflorescences. It blooms for short periods with differing bloom times depending on where the grass is located. Molasses grass generally flowers in the southern hemisphere between April and June and in the northern hemisphere in November.
