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 ...

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 other organi ...

National Center For Biotechnology Information
The National Center for Biotechnology Information (NCBI) is part of the United States National Library of Medicine (NLM), a branch of the National Institutes of Health (NIH). It is approved and funded by the government of the United States. The NCBI is located in Bethesda, Maryland, and was founded in 1988 through legislation sponsored by US Congressman Claude Pepper. The NCBI houses a series of databases relevant to biotechnology and biomedicine and is an important resource for bioinformatics tools and services. Major databases include GenBank for DNA sequences and PubMed, a bibliographic database for biomedical literature. Other databases include the NCBI Epigenomics database. All these databases are available online through the Entrez search engine. NCBI was directed by David Lipman, one of the original authors of the BLAST sequence alignment program and a widely respected figure in bioinformatics.

Frank Shipley Collins
Frank Shipley Collins (1848–1920) was an American botanist and algologist specializing in the study of marine algae.Makers of American Botany, Harry Baker Humphrey, Ronald Press Company, Library of Congress Card Number 61-18435 He was a pioneer in the study of the distribution of algae on the Atlantic seaboard and Bermudas and was the leading American algologist of his time. He wrote ''The Green Algae of North America'' and ''Working Key to the Genera of North American Algae''. Several species bear his name in his honor, including ''Collinsiella tuberculata'' (green algae in the order Ulotrichales), and ''Phaeosaccion collinsii ''Phaeosaccion'' is a genus of algae with monostromatic tubular to saccate thalli, up to long and to wide.

Marine Botany
Marine botany is the study of flowering vascular plant species and marine algae that live in shallow seawater of the open ocean and the littoral zone, along shorelines of the intertidal zone and coastal wetlands, even in low-salinity brackish water of estuaries. It is a branch of marine biology and botany. Marine Plant Classifications There are five kingdoms that present-day classifications group organisms into: the Monera, Protist, Plantae, Fungi, and Animalia. The Monera Less than 2,000 species of bacteria occur in the marine environment out of the 100,000 species. Although this group of species is small, they play a tremendous role in energy transfer, mineral cycles, and organic turnover. The monera differs from the four other kingdoms as "members of the Monera have a prokaryotic cytology in which the cells lack membrane-bound organelles such as chloroplasts, mitochondria, nuclei, and complex flagella." The bacteria can be divided into two major subkingdoms: Eubact ... [...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 phylogenetics ...

William Albert Setchell
William Albert Setchell (April 15, 1864 – April 5, 1943) was an American botanist and marine phycologist who taught at the University of California, Berkeley, where he headed the Botany Department. Among his publications are the ''Phycotheca Boreali-Americana'', a multi-volume specimen collection of dried algae, and the ''Algae of Northwestern America'', a reference work. Education Setchell was born in Norwich, Connecticut, to George Case Setchell and Mary Ann (Davis) Setchell. Setchell showed an early interest in natural history that was furthered during his years at the Norwich Free Academy. He went to Yale University as an undergraduate and to Harvard University for graduate work, where he studied with William Gilson Farlow, a specialist in cryptogams. He did his thesis work on the anatomy and morphology of kelps. Career After completing his PhD in 1890, Setchell took a post at the Sheffield Scientific School of Yale University as an assistant in biology. He rose to b ...

Ulvophyceae Genera
The Ulvophyceae or ulvophytes are a class of green algae, distinguished mainly on the basis of ultrastructural morphology, life cycle and molecular phylogenetic data.Graham LE, Graham JM, Wilcox LW (2009) ''Algae''. 2nd Edition. Benjamin Cummings (Pearson), San Francisco, CA The sea lettuce, ''Ulva'', belongs here. Other well-known members include '' Caulerpa'', '' Codium'', ''Acetabularia'', '' Cladophora'', '' Trentepohlia'' and ''Monostroma''. The Ulvophytes are diverse in their morphology and their habitat. Most are seaweeds such as those listed above. Others, such as ''Rhizoclonium'', ''Pithophora'' and some species of '' Cladophora'' live in fresh water and in some areas are considered weeds. Evolution The origin and early diversification of the Ulvophyceae likely took place in the late Neoproterozoic. Although most contemporary ulvophytes are marine macroalgae (seaweeds), ancestral ulvophytes may have been freshwater, unicellular green algae. Molecular phylogenetic ...
