Socratea Salazari
''Socratea'' is a genus of five species of palms found in tropical Central America and South America. It is commonly believed that ''Socratea'' can move away from where it germinated by growing roots on one side and abandoning them on the other. Attempts to detect this behavior have failed. What is known for a fact is that these roots can, in the case of S. montana, grow to a length of 16.5 feet (five meters) and up to three inches (eight cm) in diameter. * '' Socratea exorrhiza'' (Mart.)

Gustav Karl Wilhelm Hermann Karsten
Gustav Karl Wilhelm Hermann Karsten (6 November 1817, in Stralsund – 10 July 1908, in Zoppot) was a German botanist and geologist. Born in Stralsund, he followed the example of Alexander von Humboldt and traveled 1844-56 the northern part of South America (Venezuela, Ecuador and Colombia). From 1856 to 1868, he was a professor at the agricultural college in Berlin, afterwards serving as a professor of plant physiology at the University of Vienna (1868–72). In 1881, at the suggestion of David Friedrich Weinland, Karsten became convinced of the correctness of Otto Hahn's organic theory of the chondrites and, as a result, wrote an essay entitled "Die Meteorite und ihre Organismen" in which he declared his support for Hahn's theory. He died 1908 in Berlin-Grunewald. As a taxonomist In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
