Gravenhorst
Johann Ludwig Christian Carl Gravenhorst (14 November 1777 – 14 January 1857), sometimes Jean Louis Charles or Carl, was a German entomologist, herpetologist, and zoologist. Life Gravenhorst was born in Braunschweig. His early interest in insects was encouraged by two of his professors, both amateur entomologists. He entered the University of Helmstedt to study law in 1797. However, the death of his father two years later left him a great fortune; so he was able to change his direction. He enrolled at the University of Göttingen where he followed the courses of Johann Friedrich Blumenbach. He returned to present his thesis to Helmstädt on a subject of entomology. He went to Paris in 1802 and there met Georges Cuvier, Pierre André Latreille, and Alexandre Brongniart. Parallel to his studies, he assembled, thanks to his financial means, a very important natural history collection. In 1805, he obtained a professorial chair in Göttingen and published the follow ...

Ambystoma Opacum
The marbled salamander (''Ambystoma opacum'') is a species of mole salamander found in the eastern United States. Description The marbled salamander is a stocky and boldly banded salamander. The marbled salamander exhibits sexual dimorphism with bands of females tending to be gray, while those of males are more white. Juveniles do not have any bands and have white flecks instead. Adults can grow to about 11 cm (4 in), small compared to other members of its genus. Like most of the mole salamanders, it is secretive, spending most of its life under logs or in burrows. Habitat and range Marbled salamanders are found in the eastern United States, from southern New England to northern Florida, and west to Illinois and Texas. They have been found as far north as New Hampshire, though only two sightings have been reported there. Their habitats are damp woodlands, forests, and places with soft and wet soil. Seasonally flooded areas are essential for breeding, but the salam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fejervarya Cancrivora
''Fejervarya'' is a genera of frogs in the family Dicroglossidae found in Asia. First proposed in 1915 by István József Bolkay, a Hungarian naturalist, the genus did not see widespread adoption at first. As late as the 1990s it was generally included in ''Rana'', but more recent studies have confirmed its distinctness. These frogs are remarkable for being extremely euryhaline by amphibian standards. Species such as the crab-eating frog (''F. cancrivora'') can thrive in brackish water, and its tadpoles can even survive in pure seawater. Systematics and taxonomy ''Fejervarya'' was first introduced as subgenus of ''Rana'' and later placed as subgenus as '' Limnonectes''. It was treated as an independent genus first in 1998. However, ''Fejervarya'' sensu lato was found to be paraphyletic with respect to '' Sphaerotheca''. This issue was eventually resolved in 2011 by splitting some species to the genus ''Zakerana'' (renamed in 2021 as '' Minervarya''). ''Fejervarya'', as now d ...

Liolaemus Gravenhorstii
''Liolaemus gravenhorstii'', commonly known as Gravenhorst's tree iguana, is a species of lizard in the Family (biology), family Iguanidae. The species is Endemism, endemic to South America. Etymology The Specific name (zoology), specific name, ''gravenhorstii'', is in honor of Germans, German Herpetology, herpetologist Johann Ludwig Christian Gravenhorst.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . (''Liolaemus gravenhorstii'', p. 106). Geographic range ''L. gravenhorstii'' is found in western Argentina (in the provinces of Mendoza Province, Mendoza and San Juan Province, Argentina, San Juan) and in central Chile.

Trachylepis
''Trachylepis'' is a skink genus in the subfamily Mabuyinae found mainly in Africa. Its members were formerly included in the " wastebin taxon" '' Mabuya'', and for some time in '' Euprepis''. As defined today, ''Trachylepis'' contains the clade of Afro-Malagasy mabuyas. The genus also contains a species from the Brazilian island of Fernando de Noronha, '' T. atlantica'', and may occur in mainland South America with '' Trachylepis tschudii'' and '' Trachylepis maculata'', both poorly known and enigmatic. The ancestors of ''T. atlantica'' are believed to have rafted across the Atlantic from Africa during the last 9 million years. The generic name ''Trachylepis'' literally means "rough-scaled", referring to the fact that most of the species, though superficially smooth-scaled, have three or more slight longitudinal keels on their dorsal scales. Species The following species are recognized as being valid (listed alphabetically by specific name). *'' Trachylepis acutilabri ...

Ichneumonidae
The Ichneumonidae, also known as the ichneumon wasps, Darwin wasps, or ichneumonids, are a family of parasitoid wasps of the insect order Hymenoptera. They are one of the most diverse groups within the Hymenoptera with roughly 25,000 species currently described. However, this likely represents less than a quarter of their true richness as reliable estimates are lacking, along with much of the most basic knowledge about their ecology, distribution, and evolution.Quicke, D. L. J. (2015). The braconid and ichneumonid parasitoid wasps: biology, systematics, evolution and ecology. Chichester: John Wiley & Sons, Ltd. Ichneumonid wasps, with very few exceptions, attack the immature stages of holometabolous insects and spiders, eventually killing their hosts. They thus fulfill an important role as regulators of insect populations, both in natural and semi-natural systems, making them promising agents for biological control. The distribution of the ichneumonids was traditionally consi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Helmstedt
The University of Helmstedt (german: Universität Helmstedt; official Latin name: ''Academia Julia'', "Julius University"), was a university in Helmstedt in the Duchy of Brunswick-Wolfenbüttel that existed from 1576 until 1810. History Founded by and named after Duke Julius of Brunswick-Wolfenbüttel on 15 October 1576, the first university of the duchy and the first Protestant university of the northern Holy Roman Empire quickly became one of the largest German universities. In order to train pastors and administrators for work in the Lutheran churches, the duchy needed a university of its own. In 1575, Julius obtained the Emperor's permission to open a university in Helmstedt. One year later the first lectures started. The princes of Wolfenbüttel held the office of the rector, starting with Julius' 12-year-old son John Henry. Tilemann Heshusius was an important early Lutheran theologian at Helmstedt. He developed a clergy network in the region that supported other Hel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andaman Islands
The Andaman Islands () are an archipelago in the northeastern Indian Ocean about southwest off the coasts of Myanmar's Ayeyarwady Region. Together with the Nicobar Islands to their south, the Andamans serve as a maritime boundary between the Bay of Bengal to the west and the Andaman Sea to the east. Most of the islands are part of the Andaman and Nicobar Islands, a Union Territory of India, while the Coco Islands and Preparis Island are part of the Yangon Region of Myanmar. The Andaman Islands are home to the Andamanese, a group of indigenous people that includes a number of tribes, including the Jarawa and Sentinelese. While some of the islands can be visited with permits, entry to others, including North Sentinel Island, is banned by law. The Sentinelese are generally hostile to visitors and have had little contact with any other people. The government protects their right to privacy.

West Indies
The West Indies is a subregion of North America, surrounded by the North Atlantic Ocean and the Caribbean Sea that includes 13 independent island countries and 18 dependencies and other territories in three major archipelagos: the Greater Antilles, the Lesser Antilles, and the Lucayan Archipelago. The subregion includes all the islands in the Antilles, plus The Bahamas and the Turks and Caicos Islands, which are in the North Atlantic Ocean. Nowadays, the term West Indies is often interchangeable with the term Caribbean, although the latter may also include some Central and South American mainland nations which have Caribbean coastlines, such as Belize, French Guiana, Guyana, and Suriname, as well as the Atlantic island nations of Barbados, Bermuda, and Trinidad and Tobago, all of which are geographically distinct from the three main island groups, but culturally related. Origin and use of the term In 1492, Christopher Columbus became the first European to record ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
