Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simuliidae
A black fly or blackfly (sometimes called a buffalo gnat, turkey gnat, or white socks) is any member of the family Simuliidae of the Culicomorpha infraorder. It is related to the Ceratopogonidae, Chironomidae, and Thaumaleidae. Over 2,200 species of black flies have been formally named, of which 15 are extinct. They are divided into two subfamilies: Parasimuliinae contains only one genus and four species; Simuliinae contains all the rest. Over 1,800 of the species belong to the genus ''Simulium''. Most black flies gain nourishment by feeding on the blood of mammals, including humans, although the males feed mainly on nectar. They are usually small, black or gray, with short legs, and antennae. They are a common nuisance for humans, and many U.S. states have programs to suppress the black fly population. They spread several diseases, including river blindness in Africa (''Simulium damnosum'' and ''S. neavei'') and the Americas (''S. callidum'' and ''S. metallicum'' in Central Am ...

Simulium
''Simulium'' is a genus of black flies, which may transmit diseases such as onchocerciasis (river blindness). It is a large genus with several hundred species, and 41 subgenera. The flies are pool feeders. Their saliva, which contains anticoagulants, a number of enzymes and histamine, is mixed with the blood, preventing clotting until it is ingested by the fly. These bites cause localized tissue damage, and if the number of feeding flies is sufficient, their feeding may produce a blood-loss anaemia. The host's reaction to fly attacks may include systemic illness, allergic reactions or even death, presumably mediated by histamine. In humans, this systemic reaction is known as "black fly fever" and is characterized by headaches, fever, nausea, adenitis, generalized dermatitis, and allergic asthma.

Émile Roubaud
Émile Roubaud (2 March 1882 in Paris – 30 September 1962 in Paris) was a French biologist and entomologist known for his work on paludism, yellow fever and African trypanosomiasis, sleeping sickness. Biography In 1906-08 he worked in the French Congo, where he studied the transmission of trypanosomiasis and the role of tsetse flies. In 1909-12 he took part in a mission in Senegal, Casamance and French Dahomey, Dahomey, where he performed research of animal trypanosomiasis. On this mission he conducted geographical distribution studies of nine tsetse fly species.Emile Roubaud (1882-1962) Service des Archives de l'Institut Pasteur In 1920, he and Félix Mesnil achieved the first experimental infection of Common chimpanzee, chimpanzees with ''Plasmodium vivax''. He made his career at Pasteur Institute — ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuku Hiva
Nuku Hiva (sometimes spelled Nukahiva or Nukuhiva) is the largest of the Marquesas Islands in French Polynesia, an overseas country of France in the Pacific Ocean. It was formerly also known as ''Île Marchand'' and ''Madison Island''. Herman Melville wrote his book ''Typee'' based on his experiences in the Taipivai valley in the eastern part of Nuku Hiva. Robert Louis Stevenson's first landfall on his voyage on the ''Casco'' was at Hatihe'u, on the north side of the island, in 1888. Geography Coast Western Nuku Hiva is characterized by a steep but fairly regular coastline, indented occasionally by small bays, leading to deep valleys, which in turn lead into the interior. There are no villages on the western side. The coastline of the eastern part of the island has few places to land by sea and takes the brunt of the ocean swells. The northern side, in contrast, is indented by deep bays, the largest of which are Anahō and Hatihe'u. A third bay, 'A'akapa, is smaller and li ...

Eiao
Eiao is the largest of the extreme northwestern Marquesas Islands. The island is uninhabited, but is administratively part of the commune (municipality) of Nuku-Hiva, itself in the administrative subdivision of the Marquesas Islands. Geography The center of this island is a high plateau, rising on the east side to 576 metres above sea level (1,890 feet), much of which has been devastated by herds of feral sheep brought here by mankind. There is one good anchorage, found on the western side of the island at Vaituha. History In pre-European times, the bodies of chiefs from parts of Te I'i were taken to Eiao for burial. Eiao was at one time home to a Marquesan tribe called the Tuametaki. Archaeological investigations have discovered workshops for the production of stone tools, especially adzes, made from local basalt. These tools have been found in archaeological sites on other islands, providing evidence for prehistoric interisland voyaging within this island group. The popul ...
