Balliales
Balliales is an order of red algae belonging to the class Florideophyceae. The order consists only one family, Balliaceae. with only one genus - Ballia Harvey. The genus of ''Balliales'' was circumscribed by William Henry Harvey in J. Bot. (Hooker) vol.2 on page 191 in 1840. The genus name of ''Balliales'' is in honour of Anne Elizabeth Ball (1808–1872), who was an Irish botanist, amateur algologist, and botanical illustrator.

Red Algae
Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The majority of species (6,793) are found in the Florideophyceae (class), and mostly consist of multicellular, marine algae, including many notable seaweeds. Red algae are abundant in marine habitats but relatively rare in freshwaters. Approximately 5% of red algae species occur in freshwater environments, with greater concentrations found in warmer areas. Except for two coastal cave dwelling species in the asexual class Cyanidiophyceae, there are no terrestrial species, which may be due to an evolutionary bottleneck in which the last common ancestor lost about 25% of its core genes and much of its evolutionary plasticity. The red algae form a distinct group characterized by having eukaryotic cells without flagella and centrioles, chloroplasts that l ...

Florideophyceae
Florideophyceae is a class of red algae. They were once thought to be the only algae to bear pit connections, but these have since been found in the filamentous stage of the Bangiaceae. They were also thought only to exhibit apical growth, but there are genera known to grow by intercalary growth. Most, but not all, genera have three phases to the life cycle. Classification There are various classification schemes; see red algae. One option is to use the following: Subclass Hildenbrandiophycidae * Hildenbrandiales Subclass Nemaliophycidae * Acrochaetiales * Balbianiales * Balliales * Batrachospermales * Colaconematales * Nemaliales * Palmariales * Entwisleiales * Thoreales Subclass Corallinophycidae * Corallinales * Corallinapetrales * Rhodogorgonales * Sporolithales The subclass Corallinophycidae was introduced in 2007. Subclass Ahnfeltiophycidae * Ahnfeltiales * Pihiellales Subclass Rhodymeniophycidae * Bonnemaisoniales * Ceramiales * Gelidiales * G ...

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 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. After leaving school he joined the family business. Harvey was an authority on algae and bryophytes ( mosses), and author of ''A Manual of the British Algae'' (1841), ''Phycologia Britannica'' (4 vols., 1846–51), ''Nereis Boreali-Americana.'' (3 parts 1852–85) and '' Phycologia Australica'' (5 vol., 1858–63). He spent several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anne Elizabeth Ball
Anne Elizabeth Ball (1808–1872) was an Irish botanist, amateur algologist, and botanical illustrator. Born in Cobh 1808, Ball was a sister of naturalist Robert Ball (1802–1857) and zoologist Mary Ball (1812–1898). The siblings became interested in natural history through the passion of their father, Bob Stawell Ball. Background In 1818, Anne Ball moved from her birthplace of Cobh to Youghal, another seaport town in County Cork, with her family and it was here that Ball, in her early twenties, began to collect and study marine algae. In 1837, her sister and father moved away from Cork to Dublin, where she resided until her death. Anne continued her algae collecting in Dublin and, although not a member of the Dublin scientific societies, Anne established herself as a successful algologist. However, as was then the custom, her work was published by male naturalists such as William Henry Harvey (a friend of her brother's), James Mackay, and others. However these relations ...

Phycology
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] |
AlgaeBase
AlgaeBase is a global species database of information on all groups of algae, both marine and freshwater, as well as sea-grass. History AlgaeBase began in March 1996, founded by Michael Guiry. Text was copied from this source, which is available under Attribution 4.0 International (CC BY 4.0)licence. (Sehere. By 2005, the database contained about 65,000 names. In 2013, AlgaeBase and the Flanders Marine Institute (VLIZ) signed an end-user license agreement regarding the Electronic Intellectual Property of AlgaeBase. This allows the World Register of Marine Species (WoRMS) to include taxonomic names of algae in WoRMS, thereby allowing WoRMS, as part of the Aphia database, to make its overview of all described marine species more complete. Synchronisation of the AlgaeBase data with Aphia and WoRMS was undertaken manually until March 2015, but this was very time-consuming, so an online application was developed to semi-automate the synchronisation, launching in 2015 in conju ...

Ballia Callitricha
Ballia is a city with a municipal board in the Indian state of Uttar Pradesh. The eastern boundary of the city lies at the junction of two major rivers, the Ganges and the Ghaghara.The city is situated east of Varanasi and about 380 km from the state capital Lucknow. It has a protected area, the Jai Prakash Narayan bird sanctuary. Ballia is also around away from Bihar.Ballia is also known for their freedom fighters.This is very poppular amongst people because of famous personalities like "Ex Prime Minister Shri Chandrasekhar ji and Chittu Pandey ji. Etymology According to locals, the name Ballia was derived from the name of the sage Valmiki, the author of Ramayana. Valmiki resided here at one point, and the place was commemorated by a shrine (although it has long since been washed away). Another belief about the origin of the name is that it refers to the sandy quality of the soil, locally known as "Ballua" (''balu'' meaning sand)..During the Quit India Movement of 1942, ...
