Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the opposite wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically 'extent' , is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is the distance between the length from the end of an individual's arm (measured at the fingertips) to the individual's fingertips on the other arm when raised parallel to the ground at shoulder height. Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, regardless of wing shape or sweep. Implications for aircraft design and animal evolution The lift from wings is proportional to their area, so the h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imago
In biology, the imago (Latin for "image") is the last stage an insect attains during its metamorphosis, its process of growth and development; it is also called the ''imaginal'' stage ("imaginal" being "imago" in adjective form), the stage in which the insect attains maturity. It follows the final ecdysis of the immature instars. In a member of the Ametabola or Hemimetabola, species in which metamorphosis is "incomplete", the final ecdysis follows the last immature or '' nymphal'' stage. In members of the Holometabola, in which there is a pupal stage, the final ecdysis follows emergence from the pupa A pupa (; : pupae) is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages th ..., after which the metamorphosis is complete, although there is a prolonged period of maturation in some species. The imago is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Life Cycle
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the process repeating in a cyclic fashion. "The concept is closely related to those of the life history, Developmental biology, development and ontogeny, but differs from them in stressing renewal." Transitions of form may involve growth, asexual reproduction, or sexual reproduction. In some organisms, different "generations" of the species succeed each other during the life cycle. For Embryophyte, plants and many algae, there are two multicellular stages, and the life cycle is referred to as alternation of generations. The term life history is often used, particularly for organisms such as the red algae which have three multicellular stages (or mor ...

Sempervivum
''Sempervivum'' () is a genus of about 40 species of flowering plants in the family (biology), family Crassulaceae, commonly known as houseleeks. Other common names include liveforever (the source of the taxonomical designation ''Sempervivum'', literally "always/forever alive") and hen and chicks, a name shared with plants of other Hen and Chicken plant, genera as well. They are succulent plant, succulent perennial plant, perennials forming mats composed of tufted leaves in rosettes. In favourable conditions they spread rapidly via offset (botany), offsets, and several species are valued in cultivation as groundcover for dry, sunny locations. Habitat Houseleeks exist from Morocco to Iran, through the mountains of Iberia, the Alps, Carpathians, Balkan mountains, Turkey, the Armenian mountains, in the northeastern part of the Sahara Desert, and the Caucasus. Their ability to store water in their thick leaves allows them to Lithophyte, live on sunny rocks and stony places in the moun ...

Hylotelephium Caucasicum
''Hylotelephium'' is a genus of flowering plants in the stonecrop family Crassulaceae. It includes about 33 species distributed in Asia, Europe, and North America. Species in the genus, formerly included in ''Sedum'', are popular garden plants, known as sedum, stonecrop, live-for-ever, or orpine. Horticulturalists have hybridised many of the species to create new cultivars. Many of the newer ones are patented, so may not be propagated without a license. Taxonomy ''Hylotelephium telephium'' and related species have been considered in a number of different ways since first being described by Linnaeus in 1753, including as a section of ''Sedum'' by Gray in 1821, or a subgenus. But these taxa are quite distinct from ''Sedum'' morphologically. ''Hylotelephium'' is one of a group of genera that form a separate lineage from ''Sedum'', and is closely related to ''Orostachys'', '' Meterostachys'', and ''Sinocrassula''. The separation and recognition of ''Hypotelephium'' as a genus se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedum Ropsea
''Sedum'' is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species, subsequently reduced to 400–500. They are leaf succulents found primarily in the Northern Hemisphere, but extending into the southern hemisphere in Africa and South America. The plants vary from annual and creeping herbs to shrubs. The plants have water-storing leaves. The flowers usually have five petals, seldom four or six. There are typically twice as many stamens as petals. Various species formerly classified as ''Sedum'' are now in the segregate genera ''Hylotelephium'' and ''Rhodiola''. Well-known European species of ''Sedum'' are ''Sedum acre'', '' Sedum album'', '' Sedum dasyphyllum'', and '' Sedum hispanicum''. Description ''Sedum'' is a genus that includes annual, biennial, and perennial herbs. They are characterised by succulent leaves and stems. The extent of morphological diver ...

Sedum Rupestre
''Petrosedum rupestre'', also known as reflexed stonecrop, Jenny's stonecrop, blue stonecrop, stone orpine, prick-madam and trip-madam, is a species of perennial succulent flowering plant in the family Crassulaceae, native to northern, central, and southern Europe. Description ''Petrosedum rupestre'' plants are typically up to 10 cm high, with sprawling stems and stiff foliage resembling spruce branches, with softer tissue. The leaves are frequently blue-gray to gray but range to light greens and yellows; the flowers are yellow. Like many ''Sedum'' species, it has a prostrate, spreading habit. Cultivation ''Petrosedum rupestre'' is a popular ornamental plant, grown in gardens, containers, and as houseplants. It is drought-tolerant. There are named cultivars with variegated (multi-colored) leaves. Through vegetative cloning it is propagated from cuttings. This sedum is prone to fasciation (cristate forms), which produces attractive cactus-like forms, with irregular curv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedum Album
''Sedum album'', the white stonecrop, is a flowering plant of the genus ''Sedum'' in the family Crassulaceae. It is found in the northern temperate regions of the world, often growing in crevices or free-draining rocky soil. As a long-day plant it grows vegetatively for most of the year and flowers in summer. Taxonomy Three subspecies ''album'', ''micranthum'' (Bastard ex DC.) Syme and ''teretifolium'' Syme have been described. In 2015, a new subspecies '' rupimelitense'' was described in Malta. Description White stonecrop is a tufted perennial herb that forms mat-like stands. Much of the year the stems are short, semi prostrate and densely clad in leaves. At the flowering time in July and August, the stems lengthen and are erect, occasionally branched and often pinkish-brown. The leaves are alternate, fleshy and nearly cylindrical with a blunt, rounded tip. They are also sometimes tinged with pink, especially in drought-stressed plants. The starry flowers form a dense cyme. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedum Telephium
''Hylotelephium telephium'' (synonym ''Sedum telephium''), known as orpine, livelong, frog's-stomach, harping Johnny, life-everlasting, live-forever, midsummer-men, Orphan John, witch's moneybags, and garden stonecrop is a succulent perennial plant of the family Crassulaceae native to Eurasia. The flowers are held in dense heads and can be reddish or yellowish-white. A number of cultivars, often with purplish leaves, are grown in gardens as well as hybrids between this species and the related ''Hylotelephium spectabile'' (iceplant), especially the popular 'Herbstfreude' ('Autumn Joy'). Occasionally garden plants may escape and naturalise as has happened in parts of North America. Taxonomy The plant was known to botanists, including Dioscorides (, 40 AD – 90 AD) in his De Materia Medica () as Telephion (). Pliny, Gerard and Parkinson were among many later authors to describe ''Telephium''. It was first formally described by Linnaeus in 1753, as one of 15 species of ''Sedum'' ...

Mating Plug
A mating plug, also known as a copulation plug, vaginal plug, sperm plug, or sphragis (Latin, from , "a seal"), is a gelatinous secretion used in the mating of some species. It is deposited by a male into a female genital tract, such as the vagina, and later hardens into a plug or glues the tract together. While females can expel the plugs afterwards, the male's sperm still gets a time advantage in getting to the egg, which is often the deciding factor in fertilization. The mating plug plays an important role in sperm competition and may serve as an alternative and more advantageous strategy to active mate guarding. In some species, such a passive mate-guarding strategy may reduce selection on large male size. Such a strategy may be advantageous because it would allow a male to increase reproductive success by spending more time pursuing new female mates rather than active mate guarding. Composition The mating plug of the ''Bombus terrestris'' was chemically analyzed and found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
