Liagoraceae
Liagoraceae is a family of red algae (Rhodophyta) in the order Nemaliales. The type genus is ''Liagora'' . It was originally called ''Helminthocladiaceae'' by J.Agardh in 1851, but P. Silva in 1980 stated that this was predated by Liagoraceae which was published in 1843. Various authors over several years, had tried to form tribes within the family, but it was found (each time) that the family is not able to be divided naturally. As the morphological character analyses show too much variation. The family was found to be polyphyletic (having a mixed evolutionary origin) based on analyses of rbcL enzymes. The 2 genera of ''Yamadaella'' and ''Liagoropsis'', which were previously placed in the Dermonemataceae family, were found to have independent lineages and could be recognized as two new families ''Yamadaellaceae'' and ''Liagoropsidaceae''. Description Many species are irregular and paniculate (much-branched). They have a basic dichotomous branching but with numerous proliferous ...

Scinaiaceae
Scinaiaceae is a family of red algae ( Rhodophyta) in the order Nemaliales. Huisman had placed former members of Galaxauraceae family, that were lacking lime into his new family of Scinaiaceae. Distribution The family has cosmopolitan distribution. Including being found in India, Arabian Sea, Brazil, North America (including Alaska, British Columbia, Washington, and Oregon) Chile, New Zealand (Tasmania and Campbell Island) and the Falkland Islands. Notes Molecular analyses of DNA on species of ''Nothogenia'' has been carried out to determine species relationships. Most Scinaiaceae species produce mucilage (thick, gluey substance) mainly in the cortical layer. Several species in the Scinaiaceae family (including '' Nothogenia fastigiata'' and '' Scinaia hatei'') have been screened for anti-viral activity (against herpes, Respiratory syncytial virus (RSV), Influenzavirus A, Influenzavirus B and simian immunodeficiency viruses). Sulfated polysaccharides (xylomannans) from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Galaxauraceae
Galaxauraceae is a family of red algae (Rhodophyta) in the order Nemaliales. The type genus is ''Galaxaura''. The name ''Galaxauraceae'' was first published by Russian botanist Paulus Horaninow (1796-1865) in 1843. The family has cosmopolitan distribution.

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 ...

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 ...
