Franz Unger
Franz Joseph Andreas Nicolaus Unger (30 November 1800 in ''Gut Amthof'' near village Leutschach in Styria, Austria – 13 February 1870 in Graz) was an Austrian botanist, paleontologist and plant physiologist. Life and work Initially, Unger studied law at the University of Graz. In 1820 he moved to Vienna to study medicine, in 1822 he enrolled at the Charles University in Prague. In 1823 Unger returned to Vienna and completed his medical studies in 1827. From 1827 Unger practiced as a doctor in Stockerau near Vienna, then from 1830 as a court physician in Kitzbühel, Tyrol. In 1832, botanists Schott & Endl. published ''Ungeria'' is a genus of flowering plants from Norfolk Island belonging to the family Malvaceae. It was named in Franz Unger's honour. In 1836 he was named professor of botany at the University of Graz and also taught at the Joanneum (which became the Universalmuseum Joanneum and the Graz University of Technology); in 1850 professor of plant physiology in ...

Water Mould Plant Pathogens And Diseases
Water (chemical formula ) is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food, energy or organic micronutrients. Its chemical formula, H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is also the name of the liquid state of H2O at standard temperature and pressure. A number of natural states of water exist. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice may precipitate in the form of snow. The gaseous state of water is steam or water vapor. Water co ...

Species Described In 1886
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
