Jean-Gabriel Prêtre
Jean-Gabriel Prêtre (20 December 1768 – 29 April 1849) was a Swiss-French natural history painter who illustrated birds, mammals and reptiles in a large number of books. Several species of animal were named after him. Biography Prêtre was born in Geneva. His father Jean-Louis Prêtre married Judith Renauld on 28 December 1767 in the church of Saint Germain. From their marriage the children Pernette Marguerite, Jean-Gabriel and Marie were born. He worked as a natural history illustrator, first for Empress Josephine's zoo, and then for the Natural History Museum in Paris. He illustrated many books of animals and birds, and had several species named after him. Species named after Prêtre A species of worm lizard, '' Amphisbaena pretrei'', is named in his honor.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''.

Gaspard Auguste Brullé
Gaspard Auguste Brullé (7 April, 1809 – 21 January, 1873) was a French entomologist. Passionate about insects from a young age and through the intervention of Georges Cuvier, he participated in the Morea expedition organised by Jean Baptiste Bory de Saint-Vincent in 1829. In 1832, he participated in the foundation of the Société entomologique de France. The following year he became an aide-naturaliste (assistant naturalist) to Jean Victoire Audouin in charge of Crustacea, Arachnida and insects. Brullé studied for and obtained a baccalauréat in sciences then in "lettres", before qualifying in 1839 as a Doctor of Natural Science. His thesis, published in 1837, was ''Sur le gisement des insectes fossiles et sur les services que l'étude de ces animaux peut fournir à la géologie''. He became the Professor of Zoology and Comparative Anatomy at the University of Dijon. He proposed a new classification of Neuroptera which was completed by Wilhelm Ferdinand Erichson. He ...

Frédéric Jules Sichel
Frédéric Jules Sichel (14 May 1802 – 11 November 1868) was a German-born, French physician and entomologist. Sichel was born in Frankfurt am Main. From 1820 he studied medicine at the universities of Würzburg, Tübingen and Berlin, then from 1825 to 1829 worked as assistant to ophthalmologist Friedrich Jäger von Jaxtthal in Vienna. In 1829 he relocated to Paris, where in 1833 he received his doctorate with the dissertation-thesis "''Propositions générales sur l'ophthalmologie, suivies de l'histoire de l'ophthalmie rhumatismale"''. In 1833 he acquired French citizenship.SICHEL (Julius Friedrich) biuSante / Biographies In 1832 he established the first ophthalmic clinic in Paris, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crown Wasp
The Stephanidae, sometimes called crown wasps, are a family of parasitoid wasps. They are the only living members of the superfamily Stephanoidea. Stephanidae has at least 345 living species in 11 genera. The family is considered cosmopolitan in distribution, with the highest species concentrations in subtropical and moderate climate zones. Stephanidae also contain four extinct genera described from both compression fossils and inclusions in amber. Biology Stephanids are noted for their ocellar corona, a semicircular to circular set of projections around the middle ocellus, forming a "crown" on the head. Only stephanids and the similarly old Hymenoptera family Orussidae have ocellar coronae, and it is uncertain if they developed the structure separately or if a common ancestor of both developed it and it was then lost in all but the two families. Weakly developed grooves starting at the base of the antennae and extending past the eyes to the back of the head capsule are present. ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...

Type Genus
In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens for ranks up to fam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxonomic ranks from genus upwards are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
