Hawaiʻi ʻakepa
The Hawaiʻi ʻakepa (''Loxops coccineus'') is an endangered ʻakepa native to Hawaiʻi in the Hawaiian Islands. All three of the ʻakepa were considered monotypic before being split by the NACC of the AOU in 2015. The Hawaii akepa was first collected by western science during Captain James Cook's third voyage around the world. Several specimens were collected, as well as feather leis (necklaces resembling strings of flowers) constructed by Hawaiian artisans. The specimens were classified when brought back to England several years later. The Latin name of the bird, ''Loxops coccineus'', means "crossed" (''Loxops'') and "red" (''coccineus''). Description It is a four-inch (10 cm) long bird of a dusty green color. Males are bright orange. It has a small cross bill just like the other ''Loxops'' species. Its call is a slight quivering whistle ending with a long trill. Distribution and habitat The Hawaiʻi akepa survives only in two or three locations, all on the island of H ...

Hawaiian Lobelioids
The Hawaiian lobelioids are a group of flowering plants in the bellflower family, Campanulaceae, subfamily Lobelioideae, all of which are endemic to the Hawaiian Islands. This is the largest plant radiation in the Hawaiian Islands, and indeed the largest on any island archipelago, with over 125 species. The six genera involved can be broadly separated based on growth habit: ''Clermontia'' are typically branched shrubs or small trees, up to tall, with fleshy fruits; ''Cyanea'' and ''Delissea'' are typically unbranched or branching only at the base, with a cluster of relatively broad leaves at the apex and fleshy fruits; ''Lobelia'' and ''Trematolobelia'' have long thin leaves down a single, non-woody stem and capsular fruits with wind-dispersed seeds; and the peculiar ''Brighamia'' have a short, thick stem with a dense cluster of broad leaves, elongate white flowers, and capsular fruits. The relationships among the genera and sections remains unsettled . Many species have beauti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1789
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Bird ...

Endangered Fauna Of Hawaii
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] |
Endemic Fauna Of Hawaii
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] |

Anopheles
''Anopheles'' () is a genus of mosquito first described and named by J. W. Meigen in 1818. About 460 species are recognised; while over 100 can transmit human malaria, only 30–40 commonly transmit parasites of the genus ''Plasmodium'', which cause malaria in humans in endemic areas. ''Anopheles gambiae'' is one of the best known, because of its predominant role in the transmission of the most dangerous malaria parasite species (to humans) – ''Plasmodium falciparum''. The name comes from the Ancient Greek word 'useless', derived from , 'not', 'un-' and 'profit'. Mosquitoes in other genera ('' Aedes'', '' Culex'', '' Culiseta'', '' Haemagogus'', and '' Ochlerotatus'') can also serve as vectors of disease agents, but not human malaria. Evolution The ancestors of ''Drosophila'' and the mosquitoes diverged . The culicine and ''Anopheles'' clades of mosquitoes diverged between and . The Old and New World ''Anopheles'' species subsequently diverged between and . '' Anoph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mosquito
Mosquitoes (or mosquitos) are members of a group of almost 3,600 species of small flies within the family Culicidae (from the Latin ''culex'' meaning " gnat"). The word "mosquito" (formed by ''mosca'' and diminutive ''-ito'') is Spanish for "little fly". Mosquitoes have a slender segmented body, one pair of wings, one pair of halteres, three pairs of long hair-like legs, and elongated mouthparts. The mosquito life cycle consists of egg, larva, pupa, and adult stages. Eggs are laid on the water surface; they hatch into motile larvae that feed on aquatic algae and organic material. These larvae are important food sources for many freshwater animals, such as dragonfly nymphs, many fish, and some birds such as ducks. The adult females of most species have tube-like mouthparts (called a proboscis) that can pierce the skin of a host and feed on blood, which contains protein and iron needed to produce eggs. Thousands of mosquito species feed on the blood of various hosts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avian Pox
''Avipoxvirus'' (avian pox) is a genus of viruses within the family ''Poxviridae''. ''Poxviridae'' is the family of viruses which cause the afflicted organism to have poxes as a symptom. Poxviruses have generally large genomes, and other such examples include smallpox and monkeypox. Members of the genus ''Avipoxvirus'' infect specifically birds. Avipoxviruses are unable to complete their replication cycle in non-avian species. Although it is comparably slow-spreading, ''Avipoxvirus'' is known to cause symptoms like pustules full of pus lining the skin and diphtheria-like symptoms. These diphtheria-like symptoms might include diphtheric necrotic membranes lining the mouth and the upper respiratory tract. Like other avian viruses, it can be transmitted through vectors mechanically such as through mosquitoes. There is no evidence that this virus can infect humans. ''Avipoxvirus'' is a virus that is brick-shaped and is usually 200 nanometres in diameter. This is much larger tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Avian Malaria
Avian malaria is a parasitic disease of birds, caused by parasite species belonging to the genera '' Plasmodium'' and '' Hemoproteus'' (phylum Apicomplexa, class Haemosporidia, family Plasmoiidae). The disease is transmitted by a dipteran vector including mosquitoes in the case of '' Plasmodium'' parasites and biting midges for ''Hemoproteus.'' The range of symptoms and effects of the parasite on its bird hosts is very wide, from asymptomatic cases to drastic population declines due to the disease, as is the case of the Hawaiian honeycreepers. The diversity of parasites is large, as it is estimated that there are approximately as many parasites as there are species of hosts. Co-speciation and host switching events have contributed to the broad range of hosts that these parasites can infect, causing avian malaria to be a widespread global disease, found everywhere except Antarctica. Cause Avian malaria is most notably caused by ''Plasmodium relictum'', a protist that infects bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ʻAkiapolaʻau
The akiapōlāau (''Hemignathus wilsoni''), pronounced ''ah-kee-ah-POH-LAH-OW'', is a species of Hawaiian honeycreeper that is endemic to the island of Hawaii. Its natural habitats are dry and montane moist forests, and the only bird species on the island to occupy the woodpecker niche. The bird is in length, and has an unusually curved beak-(a specialist species). The akiapolaau is a pudgy bird which has a whitish bottom and tail, black legs, yellow chest, orangish head, black face mask and bill and gray black wings. The male's song is either a loud, short ''pit-er-ieu'' or a rapid ''warba-warba''. Its various calls include an upslurred whistle, a short ''cheedle-ee'' warble, and a short ''sweet''. Due to the recent disappearance of the Kauai nukupuu in the 1900s and the Maui nukupu u in the 1990s, leading to fears that they may be extinct, the akiapōlāau may be the last of its genus. It is the only member of the subgenus ''Heterorhynchus'', which has a woodpecker-like fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
