Droseraceae
Droseraceae is a family of carnivorous flowering plants, also known as the sundew family. It consists of approximately 180 species in three extant genera, the vast majority being in the sundew genus '' Drosera''. The family also contains the well-known Venus flytrap (''Dionaea muscipula'') and the more obscure waterwheel plant (''Aldrovanda vesiculosa''), both of which are the only living species of their respective genera. Representatives of the Droseraceae are found on all continents except Antarctica. Description Droseraceae are carnivorous herbaceous plants that may be annuals or perennials. Their leaves are alternate and adaxially circinate, with at least one leaf surface containing hairs with mucilage-producing glands at the tip. Their flowers are bisexual, usually with three carpels and five sepals, petals and stamens. Their pollen grains are triporate or multiporate and released in tetrads. Despite being carnivorous, their flowers are insect-pollinated, typi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilfried Krutzsch
Wilfried is a masculine German given name derived from Germanic roots meaning "will" and "peace" (''Wille'' and ''Frieden'' in German). The English spelling is Wilfrid.

Extinction
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Plant
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Pollen
Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced Gametophyte#Heterospory, microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male Conifer cone, cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it Germination, germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and Forensic science, forensics. Pollen in plants is used for transferring Ploidy#Haploid and monoploid, haploid male genetic ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Germany
East Germany, officially known as the German Democratic Republic (GDR), was a country in Central Europe from Foundation of East Germany, its formation on 7 October 1949 until German reunification, its reunification with West Germany (FRG) on 3 October 1990. Until 1989, it was generally viewed as a communist state and described itself as a Socialist state, socialist "workers' and peasants' state". The Economy of East Germany, economy of the country was Central planning, centrally planned and government-owned corporation, state-owned. Although the GDR had to pay substantial war reparations to the Soviets, its economy became the most successful in the Eastern Bloc. Before its establishment, the country's territory was administered and occupied by Soviet forces following the Berlin Declaration (1945), Berlin Declaration abolishing German sovereignty in World War II. The Potsdam Agreement established the Soviet occupation zone in Germany, Soviet-occupied zone, bounded on the east b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aldrovanda
''Aldrovanda'' is a genus of carnivorous plants encompassing one extant species ('' Aldrovanda vesiculosa'', the waterwheel plant) and numerous extinct taxa. The genus is named in honor of the Italian naturalist Ulisse Aldrovandi, the founder of the Botanical Garden of Bologna, Orto Botanico dell'Università di Bologna.Genaust, Helmut (1976). ''Etymologisches Wörterbuch der botanischen Pflanzennamen'' ''Aldrovanda vesiculosa'' has been reported from scattered locations in Europe, Asia, Africa, and Australia. Description The waterwheel is a small, free floating and rootless aquatic plant, with a length of about , and whorls of about in diameter. At every 3 to 4 cm the plant branches, sometimes forming offshoots. An average of 12 to 19 whorls spans the length of the plant, each with about 5 to 9 leaves, each up to 11 mm long. The growth is faster than terrestrial carnivorous plants, sometimes growing about 4 to 9 mm a day. In temperate regions the plant goes ...

Kibibyte
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as the Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words of 12, 18, 24, 30, 36, 48, or 60 bits, corresponding to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carnivorous Plant Newsletter
The ''Carnivorous Plant Newsletter'' is the official publication of the International Carnivorous Plant Society (ICPS), the largest such organization in the world. It is headquartered in Walnut Creek, California. History and editorship The newsletter has been published every year since its inception in 1972. It was first published as a stenciled product, with annual subscription priced at $1 for those in the contiguous United States, Mexico and Canada, and $2 for those living elsewhere. The first issue, from April 1972, opened with the following paragraph: In 1972 the newsletter had around 25 subscribers; this number quickly grew to more than 100 by June 29 of that year and reached 600 in July 1976. In 2018, the quarterly print run is 1400 copies. The newsletter began printing in a 6 by 9-inch format with color covers and limited color reproduction in some articles in volume 7 (1978).

Prehistoric Angiosperm Genera
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded.
