Ixodes Neuquenensis
''Ixodes neuquenensis'' is a species of tick that lives on the monito del monte (''Dromiciops gliroides''), a nocturnal marsupial that lives in the temperate forests of southern South America. Due to the near-threatened status of its host, ''Ixodes neuquenensis'' is also at risk. Morphology The females of ''Ixodes neuquenensis'' resemble other members of subgenus ''Ixodes'' but possess some distinct and notable morphological features. Two obvious spurs can be found on coxae II to IV. Two other species, '' I. theilerae'' from the Ethiopian realm and '' I. turdus'' from the Palaearctic realm The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Sibe ..., have two spurs on coxae II to IV as well but with differences in both shape and sizing. Female ''Ixodes neuquenensis'' also has very ...

Raúl Adolfo Ringuelet
Raúl Adolfo Ringuelet Ph.D. (1914 – 1982) was an Argentine zoologist. Ringuelet published more than 100 scientific papers on the ecology, limnology, biogeography, and conservation of South American freshwaters, and was a mentor to a whole generation of Argentine biologists.http://www.losquesevan.com/palabras-de-antano-raul-a.-ringuelet.702c , Palabras de antaño: Raúl A. Ringuelet Ringuelet's research interests were exceptionally broad, including numerous studies of leeches (Hirudinea), harvestmen spiders (Opiliones), crustaceans, chironomid flies and Neotropical fishes. The UNLP is named in his honor. Ringuelet was born in La Plata, September 10, 1914. He graduated in 1939 with a Doctor of Natural Sciences at the Institute of Museum, Universidad Nacional de La Plata(UNLP)http://www.efn.uncor.edu/dep/divbioeco/DivAni1/aracnol/ringuelet.html , Luis E. Acosta. Notas biográficas de aracnólogos argentinos Ringuelet published his first scientific work in 1936. Ringuelet went ...

Tick
Ticks (order Ixodida) are parasitic arachnids that are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, species, and "fullness". Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families, the Ixodidae or hard ticks, and the Argasidae, or soft ticks. ''Nuttalliella,'' a genus of tick from southern Africa is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks. Adults have ovoid/pear-shaped bodies (idiosomas) which become engorged with blood when they feed, and eight legs. Their cephalothorax and abdomen are completely fused. In addit ...

Monito Del Monte
The monito del monte or colocolo opossum, ''Dromiciops gliroides'', also called ''chumaihuén'' in Mapudungun, is a diminutive marsupial native only to southwestern South America (Argentina and Chile). It is the only extant species in the ancient order Microbiotheria, and the sole New World representative of the superorder Australidelphia (all other New World marsupials are members of the paraphyletic Ameridelphia). The species is nocturnal and arboreal, and lives in thickets of South American mountain bamboo in the Valdivian temperate rain forests of the southern Andes, aided by its partially prehensile tail. It eats primarily insects and other small invertebrates, supplemented with fruit. Taxonomy and etymology ''Dromiciops gliroides'' is the sole extant member of the order Microbiotheria. It was first described by British zoologist Oldfield Thomas in 1894. The generic name ''Dromiciops'' is based on the resemblance of the monito del monte to the eastern pygmy possum (''Cerca ...

Ixodes Theilerae
''Ixodes'' is a genus of hard-bodied ticks (family Ixodidae). It includes important disease vectors of animals and humans (tick-borne disease), and some species (notably ''Ixodes holocyclus'') inject toxins that can cause paralysis. Some ticks in this genus may transmit the pathogenic bacterium ''Borrelia burgdorferi'' responsible for causing Lyme disease. Additional organisms that may be transmitted by ''Ixodes'' are parasites from the genus ''Babesia'', which cause babesiosis, and bacteria from the related genus ''Anaplasma'', which cause anaplasmosis. Species These species are recognised within the genus ''Ixodes'': *''Ixodes abrocomae'' Lahille, 1917 *''Ixodes acer'' Apanaskevich & Schenk, 2020 *''Ixodes acuminatus'' Neumann, 1901 *''Ixodes acutitarsus'' (Karsch, 1880) *''Ixodes affinis'' Neumann, 1899 *''Ixodes albignaci'' Uilenberg & Hoogstraal, 1969 *''Ixodes alluaudi'' Neumann, 1913 *'' Ixodes amarali'' Fonseca, 1935 *'' Ixodes amersoni'' Kohls, 1966 *'' Ixodes anat ...

Ethiopian Realm
The Afrotropical realm is one of Earth's eight biogeographic realms. It includes Africa south of the Sahara Desert, the majority of the Arabian Peninsula, the island of Madagascar, southern Iran and extreme southwestern Pakistan, and the islands of the western Indian Ocean. It was formerly known as the Ethiopian Zone or Ethiopian Region. Major ecological regions Most of the Afrotropic, with the exception of Africa's southern tip, has a tropical climate. A broad belt of deserts, including the Atlantic and Sahara deserts of northern Africa and the Arabian Desert of the Arabian Peninsula, separate the Afrotropic from the Palearctic realm, which includes northern Africa and temperate Eurasia. Sahel and Sudan South of the Sahara, two belts of tropical grassland and savanna run east and west across the continent, from the Atlantic Ocean to the Ethiopian Highlands. Immediately south of the Sahara lies the Sahel belt, a transitional zone of semi-arid short grassland and vachellia sav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
