Bombus Ruderarius
''Bombus ruderarius'', commonly known as the red-shanked carder bee or red-shanked bumblebee, is a species of bumblebee found in Eurasia. Description Though sometimes mistaken for ''Bombus lapidarius'', ''Bombus ruderarius'' varies slightly in appearance from ''B. lapidarius'' in several ways. ''Bombus ruderarius'' is a relatively small bumblebee with a wide abdomen, an oblong face, and a fairly long tongue. The queen has an average length of and a wingspan of , while the other castes are somewhat smaller; the workers have an average length of and the males . Their colour is prominently black, with a red tail; among males, however, a lighter form exists with yellow-green hairs on the thorax and the first two terga (abdominal segments). The corbicula (pollen basket) on the hind legs of females (queens and workers) is covered with yellow-red hair. Ecology The nest is constructed of grass or moss, on or slightly below ground, and typically contains 50 to 100 workers. Often, ...

Johannes Peter Müller
Johannes Peter Müller (14 July 1801 – 28 April 1858) was a German physiologist, comparative anatomist, ichthyologist, and herpetologist, known not only for his discoveries but also for his ability to synthesize knowledge. The paramesonephric duct (Müllerian duct) was named in his honor. Life Early years and education Müller was born in Coblenz. He was the son of a poor shoemaker, and was about to be apprenticed to a saddler when his talents attracted the attention of his teacher, and he prepared himself to become a Roman Catholic Priest. During his college course in Koblenz, he devoted himself to the classics and made his own translations of Aristotle. At first, his intention was to become a priest. When he was eighteen, his love for natural science became dominant, and he turned to medicine, entering the University of Bonn in 1819. There he received his M.D. in 1822. He then studied at the University of Berlin. There, under the influence of G. W. F. Hegel and Kar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northwest China
Northwestern China () is a region in the People's Republic of China. It consists of five provincial administrative regions, namely Shaanxi, Gansu, Qinghai, Ningxia, and Xinjiang. The region is characterized by a (semi-)arid continental climate. It has a diverse population including significant minorities such as Hui, Uyghurs and Tibetans. Culturally, the region has historically been influenced by the Silk Road. Historic security considerations Chinese dynasties from the Qin (221 BC to 207 BC) to the Qing period (1644 CE to 1911 CE) placed high priority on maintaining stability and security in the region, motivated by concerns about potential threats from the Northwest. Security concerns have continued under modern governments. During the Republic of China period, the government was only able to exercise loose control in the Northwest. In 1933, Pan-Islamic and Pan-Turkic separatists declared an Islamic Republic of East Turkestan based on constitutionally-enshrined Shari ...

Hymenoptera Of Europe
Hymenoptera is a large order (biology), order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are Parasitoid wasp, parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they reach adulthood. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek wikt:πτερόν, πτερόν (''pteron'') for wing. The Ancient Greek wikt:ὑμήν, ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings ...

Bumblebees
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus ''Bombus'', part of Apidae, one of the bee families. This genus is the only Extant taxon, extant group in the tribe Bombini, though a few extinct related genera (e.g., ''Calyptapis'') are known from fossils. They are found primarily in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified. European bumblebees have also been introduced to New Zealand and Tasmania. Female bumblebees can sting repeatedly, but generally ignore humans and other animals. Most bumblebees are eusociality, social insects that form colony (biology), colonies with a single queen. The colonies are smaller than those of honey bees, growing to as few as 50 individuals in a nest. Psithyrus, Cuckoo bumblebees are brood parasite, brood parasitic and do not make nests or form colonies; their queens aggressively invade the nests of other bumble ...

Pyrenees
The Pyrenees are a mountain range straddling the border of France and Spain. They extend nearly from their union with the Cantabrian Mountains to Cap de Creus on the Mediterranean coast, reaching a maximum elevation of at the peak of Aneto. For the most part, the main crest forms a divide between Spain and France, with the microstate of Andorra sandwiched in between. Historically, the Crown of Aragon and the Kingdom of Navarre extended on both sides of the mountain range. Etymology In Greek mythology, Pyrene is a princess who gave her name to the Pyrenees. The Greek historian Herodotus says Pyrene is the name of a town in Celtic Europe. According to Silius Italicus, she was the virgin daughter of Bebryx, a king in Mediterranean Gaul by whom the hero Hercules was given hospitality during his quest to steal the cattle of Geryon during his famous Labours. Hercules, characteristically drunk and lustful, violates the sacred code of hospitality and rapes his host's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
