Creve Coeur, Missouri
Creve Coeur is a city located in mid St. Louis County, Missouri, United States, a part of Greater St. Louis. Its population was 18,834 at the 2020 census. Creve Coeur borders and shares a ZIP code (63141) with the neighboring city of Town and Country. It is home to the headquarters of Drury Hotels, and Monsanto until its acquisition by Bayer in 2018. History The name ''crève cœur'' (, "heartbreak") is said to derive from Creve Coeur Lake. According to the city's website, the tale goes that the lake "formed itself into a broken heart" after an Indian princess's unrequited love for a French fur trapper led her to jump "from a ledge overlooking" the lake. Written accounts and archaeological finds show that Native Americans inhabited the Creve Coeur area from 9500 BC to 1800 AD. French explorers began farming and fishing in the area in the early 18th century, and fur trappers settled there in the early 19th century. When the area was acquired by the United States through the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asia Minor
Anatolia, tr, Anadolu Yarımadası), and the Anatolian plateau, also known as Asia Minor, is a large peninsula in Western Asia and the westernmost protrusion of the Asian continent. It constitutes the major part of modern-day Turkey. The region is bounded by the Turkish Straits to the northwest, the Black Sea to the north, the Armenian Highlands to the east, the Mediterranean Sea to the south, and the Aegean Sea to the west. The Sea of Marmara forms a connection between the Black and Aegean seas through the Bosporus and Dardanelles straits and separates Anatolia from Thrace on the Balkan peninsula of Southeast Europe. The eastern border of Anatolia has been held to be a line between the Gulf of Alexandretta and the Black Sea, bounded by the Armenian Highlands to the east and Mesopotamia to the southeast. By this definition Anatolia comprises approximately the western two-thirds of the Asian part of Turkey. Today, Anatolia is sometimes considered to be synonymous with ...

Tridactylidae
The Tridactylidae are a family in the insect order Orthoptera. They are small, mole-cricket-like insects, almost always less than long when mature. Generally they are shiny, dark or black, sometimes variegated or sandy-coloured. They commonly live in short tunnels and are commonly known as pygmy mole crickets, though they are not closely related to the true "mole crickets" (Ensifera), as they are included in the Caelifera suborder (related to grasshoppers). Description The Tridactylidae are small members of the Orthoptera, most species being less than 10 mm in length, though some approach 20 mm. They have a wide, but patchy, distribution on all continents but Antarctica. Being so small and inconspicuously coloured, while living in shallow burrows in moist sandy soil, they are not generally familiar to non-entomologists. They have several unusual features, for example, the posterior femora are greatly enlarged, being strongly adapted for leaping; in some species tho ...

Nomadinae
Nomadinae is a subfamily of bees in the family Apidae. They are known commonly as cuckoo bees. This subfamily is entirely kleptoparasitic. They occur worldwide, and use many different types of bees as hosts. As parasites, they lack a pollen-carrying scopa, and are often extraordinarily wasp-like in appearance. All known species share the behavioral trait of females entering host nests when the host is absent, and inserting their eggs into the wall of the host cell; the larval parasite emerges later, after the cell has been closed by the host female, and kills the host larva. The first-instar larvae of nomadines are specially adapted for this, and possess long mandibles they use to kill the host larva, though these mandibles are lost as soon as the larva molts to the second instar, at which point it simply feeds on the pollen/nectar provisions. A behavioral habit shared by adults of various genera with males of many other bee species, who also do not possess a nest to return to, i ...

Cisuralian
The Cisuralian is the first series/epoch of the Permian. The Cisuralian was preceded by the Pennsylvanian and followed by the Guadalupian. The Cisuralian Epoch is named after the western slopes of the Ural Mountains in Russia and Kazakhstan and dates between 298.9 ± 0.15 – 272.3 ± 0.5 Mya. The Cisuralian is often synonymous with the informal terms early Permian or lower Permian. It corresponds approximately with the Wolfcampian in southwestern North America. The series saw the appearance of beetles and flies and was a relatively stable warming period of about 21 million years. Name and background The Cisuralian is the first series or epoch of the Permian. The Cisuralian was preceded by the last Pennsylvanian epoch (Gzhelian) and is followed by the Permian Guadalupian Epoch. The name "Cisuralian" was proposed in 1982, and approved by the International Subcommission on Permian Stratigraphy in 1996. The Cisuralian Epoch is named after the western slopes of the Ural Mountain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strepsiptera
The Strepsiptera are an order of insects with eleven extant families that include about 600 described species. They are endoparasites in other insects, such as bees, wasps, leafhoppers, silverfish, and cockroaches. Females of most species never emerge from the host after entering its body, finally dying inside it. The early-stage larvae do emerge because they must find an unoccupied living host, and the short-lived males must emerge to seek a receptive female in her host. They are believed to be most closely related to beetles, from which they diverged 300–350 million years ago, but do not appear in the fossil record until the mid-Cretaceous around 100 million years ago. The order is not well known to non-specialists, and the nearest they have to a common name is stylops. The name of the order translates to "twisted wing"', giving rise to other common names used for the order, twisted-wing insects and twisted-winged parasites. Adult males are rarely observed, although specimen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Allodapini
The Allodapini is a tribe of bees in the subfamily Xylocopinae, family Apidae. They occur throughout sub-Saharan Africa, South East Asia, and Australasia. There is also a rare genus, Exoneuridia, that occurs in isolated regions of Turkey, Iraq, Lebanon and Iran. Many of the species in the tribe form small social colonies where a group of females cooperatively care for the developing larvae. The larvae are fed on pollen Pollen is a powdery substance produced by seed plants. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametop ... which, like most other bees, is carried on specialised hairs of the hind pair of legs, but the pollen is fed to the larvae in a progressive fashion and usually placed directly onto their bodies where they then consume it. The larvae of allodapine bees are remarkable in their complex morphology, and in most species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halictinae
Within the insect order Hymenoptera, the Halictinae are the largest, most diverse, and most recently diverged of the four halictid subfamilies. They comprise over 2400 bee species belonging to the five taxonomic tribes Augochlorini, Thrinchostomini, Caenohalictini, Sphecodini, and Halictini, which some entomologists alternatively organize into the two tribes Augochlorini and Halictini. The subfamily Halictinae also belongs to the hymenopteran monophyletic clade Aculeata, whose members are characterized by the possession of a modified ovipositor in the form of a venomous sting for predator and prey defense. Including all eusocial and cleptoparasitic Halictidae taxa, these small bees are pollen feeders who mass provision their young and exhibit a broad spectrum of behavioral social polymorphies, ranging from solitary nesting to obligate eusociality. Estimated from the fossil record, eusociality in this subfamily evolved about 20 to 22 million years ago, which is relatively ...

Entomological Society Of America
The Entomological Society of America (ESA) was founded in 1889 and today has more than 7,000 members, including educators, extension personnel, consultants, students, researchers, and scientists from agricultural departments, health agencies, private industries, colleges and universities, and state and federal governments. It serves the professional and scientific needs of entomologists and people in related disciplines. To facilitate communication among members, the ESA is divided into four sections based on entomological interests, and six branches, based on geographic proximity. The national office is located in Annapolis, Maryland. History In 1889, the American Association of Economic Entomologists was founded by Charles V. Riley, primarily focusing on economic entomology. In 1906, the Entomological Society of America was organized to address the needs of the broader dimensions of biology, taxonomy, morphology, and faunistic studies of insects.

Guggenheim Fellow
Guggenheim Fellowships are grants that have been awarded annually since by the John Simon Guggenheim Memorial Foundation to those "who have demonstrated exceptional capacity for productive scholarship or exceptional creative ability in the arts." Each year, the foundation issues awards in each of two separate competitions: * One open to citizens and permanent residents of the United States and Canada. * The other to citizens and permanent residents of Latin America and the Caribbean. The Latin America and Caribbean competition is currently suspended "while we examine the workings and efficacy of the program. The U.S. and Canadian competition is unaffected by this suspension." The performing arts are excluded, although composers, film directors, and choreographers are eligible. The fellowships are not open to students, only to "advanced professionals in mid-career" such as published authors. The fellows may spend the money as they see fit, as the purpose is to give fellows " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
