Adina (plant)
''Adina'' is a genus of 11 species of flowering plants in the family Rubiaceae. They are shrubs or small trees, native to East Asia and Southeast Asia. Description ''Adina'' is a genus of shrubs and small trees. The terminal vegetative buds are inconspicuous and loosely surrounded by the stipules. The stipules are bifid for at least 2/3 of their length. The corolla lobes are nearly valvate in bud, being subimbricate at the apex. The anthers are basifixed and introrse. The ovary has two locules, with up to four ovules per locule. Taxonomy ''Adina'' was named by Richard Salisbury in 1807 in his book, ''The Paradisus Londinensis''. The genus name is derived from the Ancient Greek word , meaning "clustered, crowded". It refers to the tightly clustered heads of flowers. The biological type for ''Adina'' consists of the specimens that Salisbury called ''Adina globiflora''.''Adina'' In: Index Nominum Genericorum. In: Regnum Vegetabile. These are now included in the species '' Adina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Moluccas
The Maluku Islands (; Indonesian: ''Kepulauan Maluku'') or the Moluccas () are an archipelago in the east of Indonesia. Tectonically they are located on the Halmahera Plate within the Molucca Sea Collision Zone. Geographically they are located east of Sulawesi, west of New Guinea, and north and east of Timor. Lying within Wallacea (mostly east of the biogeographical Weber Line), the Maluku Islands have been considered as a geographical and cultural intersection of Asia and Oceania. The islands were known as the Spice Islands because of the nutmeg, mace and cloves that were exclusively found there, the presence of which sparked colonial interest from Europe in the sixteenth century. The Maluku Islands formed a single province from Indonesian independence until 1999, when it was split into two provinces. A new province, North Maluku, incorporates the area between Morotai and Sula, with the arc of islands from Buru and Seram to Wetar remaining within the existing Maluku Province. ...

Sulawesi
Sulawesi (), also known as Celebes (), is an island in Indonesia. One of the four Greater Sunda Islands, and the world's eleventh-largest island, it is situated east of Borneo, west of the Maluku Islands, and south of Mindanao and the Sulu Archipelago. Within Indonesia, only Sumatra, Borneo, and New Guinea, Papua are larger in territory, and only Java and Sumatra have larger populations. The landmass of Sulawesi includes four peninsulas: the northern Minahassa Peninsula, Minahasa Peninsula, the East Peninsula, Sulawesi, East Peninsula, the South Peninsula, Sulawesi, South Peninsula, and the Southeast Peninsula, Sulawesi, Southeast Peninsula. Three gulfs separate these peninsulas: the Gulf of Tomini between the northern Minahasa and East peninsulas, the Tolo Gulf between the East and Southeast peninsulas, and the Bone Gulf between the South and Southeast peninsulas. The Strait of Makassar runs along the western side of the island and separates the island from Borneo. Etymology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Range (biology)
Species distribution —or species dispersion — is the manner in which a biological taxon is spatially arranged. The geographic limits of a particular taxon's distribution is its range, often represented as shaded areas on a map. Patterns of distribution change depending on the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a population, or the distribution of the entire species as a whole (range). Species distribution is not to be confused with dispersal, which is the movement of individuals away from their region of origin or from a population center of high density. Range In biology, the range of a species is the geographical area within which that species can be found. Within that range, distribution is the general structure of the species population, while dispersion is the variation in its population density. Range is often described with the following qualities: * Sometimes a distinction is made betw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda ...

Paraphyletic
In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of Synapomorphy and apomorphy, synapomorphies and symplesiomorphy, symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia (reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research
Research is "creativity, creative and systematic work undertaken to increase the stock of knowledge". It involves the collection, organization and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion on past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, Discovery (observation), discovery, interpretation (philosophy), interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemology, epistemologies, which vary considerably both within and between humanities and sciences. ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Regnum Vegetabile
The International Association for Plant Taxonomy (IAPT) is an organization established to promote an understanding of plant biodiversity, facilitate international communication of research between botanists, and oversee matters of uniformity and stability in plant names. The IAPT was founded on July 18, 1950, at the Seventh International Botanical Congress in Stockholm, Sweden. The IAPT headquarters is located in Bratislava, Slovakia. Its president, since 2017, is Patrick S. Herendeen of the Chicago Botanic Garden; vice-president is Gonzalo Nieto Feliner of the Real Jardín Botánico, Madrid; and secretary-general is Karol Marhold of the Plant Science and Biodiversity Centre, Slovak Academy of Sciences, Bratislava. Both the taxonomic journal ''Taxon'' and the series ''Regnum Vegetabile'' are published by the IAPT. The latter series includes the ''International Code of Nomenclature for algae, fungi, and plants'', ''Index Nominum Genericorum'', and ''Index Herbariorum''. Purpos ...

Biological Specimen
A biological specimen (also called a biospecimen) is a biological laboratory specimen held by a biorepository for research. Such a specimen would be taken by sampling so as to be representative of any other specimen taken from the source of the specimen. When biological specimens are stored, ideally they remain equivalent to freshly-collected specimens for the purposes of research. Human biological specimens are stored in a type of biorepository called a biobank, and the science of preserving biological specimens is most active in the field of biobanking. Quality control Setting broad standards for quality of biological specimens was initially an underdeveloped aspect of biobank growth. There is currently discussion on what standards should be in place and who should manage those standards. Since many organizations set their own standards and since biobanks are necessarily used by multiple organizations and typically are driven towards expansion, the harmonization of standard ...
