Klebahniella
''Klebahniella'' is a genus of green algae in the family Chaetophoraceae. The genus name of ''Klebahniella'' is in honour of Heinrich Klebahn (1859–1942), who was a German mycologist and phytopathologist. The genus was circumscribed by Ernst Johann Lemmermann Ernst Johann Lemmermann (27 May 1867 in Bremen – 11 May 1915 in Bremen) was a German botanist who specialized in the field of phycology.

Heinrich Klebahn
Heinrich Klebahn (20 February 1859, Bremen – 5 October 1942, Hamburg) was a German mycologist and phytopathologist. In 1884 he obtained his PhD from the University of Jena, afterwards working as a schoolteacher in Bremen (1885–1894) and Hamburg (1894-1899). From 1905 onward, he was associated with the botanical gardens at Hamburg. From 1921 to 1934 he was an honorary professor and lecturer of cryptogamy and soil biology at the ''Institut für Allgemeine Botanik'' in Hamburg.BHL Taxonomic literature : a selective guide to botanical publications Honours In 1895 named the |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should c ...

Green Algae
The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/ Streptophyta. The land plants ( Embryophytes) have emerged deep in the Charophyte alga as sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to properly include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae. Many species live most of their lives as single cells, while other species form coenobia (colonies), long filaments, or highly differentiated macroscopic seaweeds. A few oth ...

Phytopathologist
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated popul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogene ...

Ernst Johann Lemmermann
Ernst Johann Lemmermann (27 May 1867 in Bremen – 11 May 1915 in Bremen) was a German botanist who specialized in the field of phycology. During his career he taught classes (''Seminarlehrer'') in Bremen, where he also worked as a botanical assistant at the '' Städtisches Museum für Natur-, Völker- und Handelskunde''. In Bremen he was an instructor to biologist Friedrich Hustedt (1886-1968), who named the diatom species of ''Achnanthes lemmermannii'' in honor of his former teacher in 1933. He was also honoured in 1942, in ''Lemmermanniella'', which is a genus of cyanobacteria belonging to the family Synechococcaceae, and '' Lemmermannia'' which is a genus of fresh water trebouxiophyceans, named in 1904.Lemmermann, E. (1904). Das Plankton schwedischer Gewässer. Arkiv för Botanik 2 (2): 1-209. Also, the blue-green algae species, ''Anabaena lemmermannii'' was named after Lemmermann, now a synonym of ''Dolichospermum lemmermannii'' . Published works * ''Algologische ...
