Triatoma Dominicana
''Triatoma dominicana'' is an extinct species of assassin bug in the subfamily Triatominae, the kissing bugs known from early Miocene Burdigalian stage Dominican amber deposits on the island of Hispaniola. The species is known from a single 5th instar female nymph exuvia found in ''Hymenaea protera'' amber from deposits in the Dominican Republic. The holotype, deposited in the Oregon State University as specimen number He-4-73, was mined from the La Toca Dominican amber mine. The specimen was first mentioned in a 1995 paper describing the extinct tick ''Ornithodorus antiquus''. Though mostly complete the exuvia is missing the right foreleg, the left middle leg, a small section of antenna and the anteocular region. ''Triatoma dominicana'' is the first extinct Triatominae species to be described from the fossil record. Included in the amber specimen are two fecal pellets from the insect which contain preserved flagellates of the extinct ''Trypanosoma antiquus''. This associat ...

Trypanosoma Antiquus
''Trypanosoma antiquus'' is an extinct species of kinetoplastid (class Kinetoplastida), a monophyletic group of unicellular parasitic flagellate protozoa. The genus name is derived from the Greek ''trypano'' (borer) and ''soma'' (body) because of their corkscrew-like motion, and the species name from ''antiquua'' (old) reflecting the age of the specimen. All trypanosomes are heteroxenous (requiring more than one obligatory host in order to complete life cycle) or are transmitted through some variation of a vector. The species was described in 2005 by George Poinar Jr. in the journal Vector-Borne & Zoonotic Diseases from metatrypanosomes preserved in several fecal pellets encased in '' Hymenaea protera'' amber. The fossil was recovered in the Dominican Republic from early Miocene Burdigalian stage deposits on the island of Hispaniola. Included with the pellets and thought to be the origin for them, is the extinct kissing bug '' Triatoma dominicana''. This association is ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have 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 bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Amber
Amber is fossilized tree resin that has been appreciated for its color and natural beauty since Neolithic times. Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects."Amber" (2004). In Maxine N. Lurie and Marc Mappen (eds.) ''Encyclopedia of New Jersey'', Rutgers University Press, . Amber is used in jewelry and has been used as a healing agent in folk medicine. There are five classes of amber, defined on the basis of their chemical constituents. Because it originates as a soft, sticky tree resin, amber sometimes contains animal and plant material as inclusions. Amber occurring in coal seams is also called resinite, and the term ''ambrite'' is applied to that found specifically within New Zealand coal seams. Etymology The English word ''amber'' derives from Arabic (ultimately from Middle Persian ''ambar'') via Middle Latin ''ambar'' and Middle French ''ambre''. The word was adopted in Middle English in the 14th century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triatoma Rubrofasciata
''Triatoma'' is a genus of assassin bug in the subfamily Triatominae (kissing bugs). The members of ''Triatoma'' (like all members of Triatominae) are blood-sucking insects that can transmit serious diseases, such as Chagas disease. Their saliva may also trigger allergic reactions in sensitive individuals, up to and including severe anaphylactic shock. Species These are species according to reliable sources. While most species are found in the New World, a few are known from the Old World.

Endemism
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] |

Rain Forest
Rainforests are characterized by a closed and continuous tree canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforest can be classified as tropical rainforest or temperate rainforest, but other types have been described. Estimates vary from 40% to 75% of all biotic species being indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the " world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to deforestation, the resulting habitat loss and pollution of the atmosphere. Definition Rainforest are characterized by a closed and continuous tree canopy, high humidity, the presence of moisture-dependent vegetation, a moist layer of leaf ...

Trypanosoma
''Trypanosoma'' is a genus of kinetoplastids (class Trypanosomatidae), a monophyletic group of unicellular parasitic flagellate protozoa. Trypanosoma is part of the phylum Sarcomastigophora. The name is derived from the Greek ''trypano-'' (borer) and ''soma'' (body) because of their corkscrew-like motion. Most trypanosomes are heteroxenous (requiring more than one obligatory host to complete life cycle) and most are transmitted via a vector. The majority of species are transmitted by blood-feeding invertebrates, but there are different mechanisms among the varying species. Some, such as '' Trypanosoma equiperdum'', are spread by direct contact. In an invertebrate host they are generally found in the intestine, but normally occupy the bloodstream or an intracellular environment in the vertebrate host. Trypanosomes infect a variety of hosts and cause various diseases, including the fatal human diseases sleeping sickness, caused by ''Trypanosoma brucei'', and Chagas disease, caused ...

Vector (epidemiology)
In epidemiology, a disease vector is any living agent that carries and transmits an infectious pathogen to another living organism; agents regarded as vectors are organisms, such as parasites or microbes. The first major discovery of a disease vector came from Ronald Ross in 1897, who discovered the malaria pathogen when he dissected a mosquito. Arthropods Arthropods form a major group of pathogen vectors with mosquitoes, flies, sand flies, lice, fleas, ticks, and mites transmitting a huge number of pathogens. Many such vectors are haematophagous, which feed on blood at some or all stages of their lives. When the insects feed on blood, the pathogen enters the blood stream of the host. This can happen in different ways. The ''Anopheles'' mosquito, a vector for malaria, filariasis, and various arthropod-borne-viruses (arboviruses), inserts its delicate mouthpart under the skin and feeds on its host's blood. The parasites the mosquito carries are usually located in its salivary gla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithodorus Antiquus
''Ornithodoros'' is a genus in the soft-bodied tick family, Argasidae. Physiology The opening between the midgut and hindgut has been lost, making the ticks unable to pass digestive waste products out of their bodies. Taxonomy The Linnean name derives from ''ornithos'' ( gr, ὄρνιθος) and ''doros'' ( gr, Δωρόν), meaning "bird" and "gift", respectively. It contains these species: *'' Ornithodoros alactagalis'' Issaakjan, 1936 *†''Ornithodoros antiquus'' Poinar, 1995 *''Ornithodoros apertus'' Walton, 1962 *''Ornithodoros arenicolous'' Hoogstraal, 1953 *''Ornithodoros asperus'' Warburton, 1918 *''Ornithodoros atacamensis'' Muñoz-Leal, Venzal & González-Acuña, 2016 *''Ornithodoros brasiliensis'' Aragão, 1923 *''Ornithodoros cholodkovskyi'' Pavlovsky, 1930 *''Ornithodoros compactus'' Walton, 1962 *''Ornithodoros coniceps'' Canestrini, 1890 *''Ornithodoros costalis'' Diatta, Bouattour, Durand, Renaud & Trape, 2013 *''Ornithodoros coriaceus'' Koch, 1844 *''Ornit ...
