Phycologists
Phycology () is the scientific study of algae. Also known as algology, phycology is a branch of life science. Algae are important as primary producers in aquatic ecosystems. Most algae are eukaryotic, photosynthetic organisms that live in a wet environment. They are distinguished from the higher plants by a lack of true roots, stems or leaves. They do not produce flowers. Many species are single-celled and microscopic (including phytoplankton and other microalgae); many others are multicellular to one degree or another, some of these growing to large size (for example, seaweeds such as kelp and ''Sargassum''). Phycology includes the study of prokaryotic forms known as blue-green algae or cyanobacteria. A number of microscopic algae also occur as symbionts in lichens. Phycologists typically focus on either freshwater or ocean algae, and further within those areas, either diatoms or soft algae. History of phycology While both the ancient Greeks and Romans knew of algae, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Henry Harvey
William Henry Harvey, FRS FLS (5 February 1811 – 15 May 1866) was an Irish botanist and phycologist who specialised in algae. Biography Harvey was born at Summerville near Limerick, Ireland, in 1811, the youngest of 11 children. His father Joseph Massey Harvey, was a Quaker and prominent merchant. William started his education at Ballitore School in County Kildare and by the age of 15 had already established algae as his over-riding interest.Papenfuss, G.F. 1976. pp.21–46. Landmarks in Pacific North American Marine Phycology. ''in'' Abbott, I.A. and Hollenberg, G.J. 1976. ''Marine Algae of California''. Stanford University Press, California.

Jean Pierre Étienne Vaucher
Jean Pierre Étienne Vaucher (17 April 1763 – 5 or 6 January 1841) was a Swiss Protestant pastor and botanist who was a native of the Republic of Geneva. He studied theology at Geneva, and from 1795 to 1821 was a pastor at the Church of Saint-Gervais. From 1808 to 1840 he was a professor of church history at the University of Geneva, and for a number of years he also taught classes in botany. Among his better-known students were botanist Augustin Pyramus de Candolle (1778-1841), scientist Hans Conrad Escher von der Linth (1767-1823) and Charles-Albert (1798-1849), the future King of Sardinia. Vaucher is remembered for his research involving the developmental history of algae. In his 1803 treatise ''Histoire des Conferves d'eau douce'', he described the process of conjugation in certain algae as a distinct sexual process. The phenomena of conjugation is a means of fertilization that takes place in green algae such as ''Spirogyra''. He is credited for describing the devel ...

Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in plast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anna Weber-van Bosse
Anna Antoinette Weber-van Bosse (27 March 1852 – 29 October 1942) was a Dutch phycologist, specializing in marine algae. Life Her interest in botany and zoology started at a young age, inspired by regular trips to the Amsterdam zoo. She attended the University of Amsterdam in 1880, where she was made to do her laboratory work in a room separate from the male students. Some of her greatest work comes from the ''Siboga'' Expedition, considered the most important expedition for marine phycology in the western Pacific for the nineteenth century. She ventured with her husband, Max Weber. These travels brought about numerous discoveries, including entire new genera of algae, such as '' Periphykon'', '' Exophyllum'', and '' Microphyllum''. Much of her discoveries from this trip are documented in her monograph ''Corallinaceae'' (1904), and her four-volume ''Liste des algues du Siboga'' (1913-1928). Some of her discoveries came during earlier expeditions to northern Norway and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Identification Key
In biology, an identification key, taxonomic key, or biological key is a printed or computer-aided device that aids the identification of biological entities, such as plants, animals, fossils, microorganisms, and pollen grains. Identification keys are also used in many other scientific and technical fields to identify various kinds of entities, such as diseases, soil types, minerals, or archaeological and anthropological artifacts. Traditionally identification keys have most commonly taken the form of single-access keys. These work by offering a fixed sequence of ''identification steps'', each with multiple alternatives, the choice of which determines the next step. If each step has only two alternatives, the key is said to be dichotomous, else it is polytomous. Modern multi-access or ''interactive keys'' allow the user to freely choose the identification steps and their order. At each step, the user must answer a question about one or more features (''characters'') of the e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Kaye Greville
Dr. Robert Kaye Greville FRSE FLS LLD (13 December 1794 – 4 June 1866) was an England, English mycologist, bryology, bryologist, and botanist. He was an accomplished artist and illustrator of natural history. In addition to art and science he was interested in causes like Abolitionism in the United Kingdom, abolitionism, capital punishment, keeping Sunday special and the temperance movement. He has a mountain in Queensland named after him. Biography Greville was born at Bishop Auckland, County Durham, Durham, but was brought up in Derbyshire by his parents Dorothy ( Chaloner) and Robert Greville. His father who liked to compose was the rector of St James' Church, Edlaston, the parish church in Edlaston in Derbyshire. Greville had an interest in natural history since he was very young, but he originally studied medicine. Realising that he did not need an income he discarded four years of medical education in London and Edinburgh and decided to concentrated on botany which ...

Friedrich Traugott Kützing
Friedrich Traugott Kützing (8 December 1807 in Kalbsrieth, Ritteburg – 9 September 1893) was a German pharmacist, botanist and phycologist. Despite his limited background in regard to higher education, Kützing made significant scientific contributions. In 1833, he demonstrated differences between diatoms and desmids, thus separating the two groups into families of their own. Also, independent of Charles Cagniard-Latour (1777–1859) and Theodor Schwann (1810–1882), he was among the first to provide comprehensive answers in regard to yeast and the role it played in fermentation. In 1849, he published ''Species Algarum'', a massive work that provided descriptions for 6000 species of algae. He is the binomial authority, taxonomic authority of the genera ''Syringodium'' (family Cymodoceaceae) and ''Phlebothamnion'' (family Ceramiaceae). Early life As a young man, he worked in several pharmacies in Germany, also serving as assistant for a few semesters at the chemical-pharma ...
