''Pabia signiensis'', the only species in the genus ''Pabia'', is regarded as a synonym A synonym is a word, morpheme, or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language.

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Algae
The green algae (: green alga) are a group of chlorophyll-containing autotrophic eukaryotes consisting of the phylum Prasinodermophyta and its unnamed sister group that contains the Chlorophyta and Charophyta/ Streptophyta. The land plants ( Embryophytes) have emerged deep within the charophytes as a sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to 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 (spherical), and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae, many of which live most of their lives as single cells, while other species form coenobia (colonies), long filaments ...

Koliellaceae
Koliellaceae is a family of green algae in the order Prasiolales. Koliellaceae was circumscribed by František Hindák in 1996 to include various green algae that reproduce mainly by simple cell division. Cells are solitary or found in small colonies or filaments. Cells are cylindrical to spherical, with or without a layer of mucilage. The cell wall may be smooth or covered with granulations. Cells contain a single, parietal chloroplast with or without a pyrenoid. Reproduction is typically by cell division into two equally sized cells; however, aplanospores or zoospores may be formed occasionally. Sexual reproduction is oogamous. The taxonomy of this family is problematic because molecular phylogenetics have shown the type genus ''Koliella'' is polyphyletic. The type species of ''Koliella'', ''Koliella spiculiformis, K. spiculiformis'', forms a clade that is closely related to ''Chlorella''; meanwhile, most other species of ''Koliella'' and ''Raphidonema'' are part of a clade inc ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prasiolales
Prasiolales is an order (biology), order of green algae in the Class (biology), class Trebouxiophyceae. Members of this order are ecologically widespread and are found in freshwater, marine, and terrestrial habitats from the Arctic to the Antarctic. Morphological features include a single stellate, axial chloroplast with a central pyrenoid. The ultrastructure of Prasiolales is unique and includes cells with four flagella, with their basal flagellar apparatuses in a counterclockwise orientation. For a long time, its placement was uncertain and debated between Ulvophyceae and Trebouxiophyceae (also known as Pleurastrophyceae). Molecular data, however, have robustly supported its placement in the latter class. Traditionally the order contained a single family, Prasiolaceae. Molecular phylogenetics studies have found that coccoid algae of very simple morphology, such as ''Stichococcus'', also belong to this order. Genera of uncertain placement to family include: *''Edaphochlorella'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
