Erich Werdermann
Erich Werdermann (2 March 1892 – 20 April 1959) was a German botanist. Born in Berlin, Erich Werdermann was the son of the landowner Carl Werdermann. He first studied in Jena, but then switched to Friedrich Wilhelm University (now called Humboldt University of Berlin) in Berlin. In 1914 shortly before his graduation, Werdermann was enlisted in the army and in 1915 promoted to the rank of officer. After recovering from serious wounds suffered in 1918, he was able to continue his studies. The following year Werdermann graduated as a plant physiologist at Gottlieb Haberlandt. From 1919 to 1920 he worked at the Imperial Biological Institute in Berlin, where Peter Claussen (1877–1959) sparked his interest in fungi. From 1920 to 1921, Mann was a research assistant at the Imperial Health Office with Ernst Friedrich Gilg, who introduced him to the Botanical Museum Berlin-Dahlem. In 1921, he succeeded Rudolf Schlechter as the curator of mushrooms in the herbarium of the museum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ...

Cactaceae
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only Thorns, s ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orto Botanico Dell'Università Di Genova
The Orto Botanico dell'Università di Genova (1 hectare), also known as the Orto Botanico di Genova, is a botanical garden operated by the University of Genoa, and located at Corso Dogali, Genoa, Liguria, Italy. The garden was established in 1803 by Professor Domenico Viviani on the former estate of the Jesuit College of St. Jerome in Balbi. By 1819 its catalog listed 1011 taxa, of which 60% were medicinal plants of European origin. It was extended in 1835 by an additional 4,000 square metres spread over two large terraces. The first large greenhouse was built in 1859, and in 1865 additional land was purchased to bring the garden to its current size of about 10,000 m². Today the garden contains about 4000 specimens, representing about 2000 taxa. Some date back a century or more, including fine specimens of ''Cedrus libani'', ''Cupressus sempervirens'', ''Firmiana simplex'', ''Gleditsia triacanthos'', and ''Sequoia sempervirens'', as well as ''Angiopteris evecta'', ''Arbutus canari ...

Cochemiea
''Cochemiea'' is a genus of cactus. It has previously been synonymized with ''Mammillaria'', but molecular phylogenetic studies have shown that when broadly circumscribed, ''Mammillaria'' is not monophyletic, and ''Cochemiea'' has been accepted as a separate genus. Taxonomy A 2021 molecular phylogenetic study of the "mammilloid clade", which included the genera ''Cochemiea'', ''Coryphantha'', ''Cumarinia'', ''Escobaria'', ''Mammillaria'', ''Neolloydia'' and ''Ortegocactus'', showed that it consisted of four monophyletic groups, which the authors re-circumscribed into four genera: '' Cumarinia''; ''Mammillaria'', with a reduced number of species; ''Coryphantha'', expanded to include species previously placed in ''Mammillaria'' and ''Escobaria''; and ''Cochemiea'', expanded to include a large number of species previously placed in ''Mammillaria'', as well as ''Neolloydia conoidea''. Species In 2021, Breslin, Wojciechowski and Majure placed the following species in the genus, some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of Durango
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms ''gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de Phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
