Caulerpa Subserrata
''Caulerpa subserrata'' is a species of seaweed in the '' Caulerpaceae'' family. Description The seaweed has erect fronds that arise from repeating, cylindrically shaped, branching, glabrous surculus and often two or three individuals are found together. It is flat and has a linear or elliptic to oblong shape in outline. The fronds are truncato-obtuse at apex and oval at the base tapering to a very short cylindrical stipe. The fronds are long and wide. It can be simple or branches by proliferations and is serrated with lobes along both margins. The lobes are short, patent and a little curved upward and subalternate. Taxonomy The species was first formally described by the botanist Kintarô Okamura in 1897 as part of the work ''On the algae from Ogasawara-jima (Bonin Islands)'' as published in the ''Botanical Magazine, Tokyo''. Distribution It is found along the coast of the Bonin Islands about south of Japan. References {{Taxonbar, from=Q60185206 subserrata Species ...

Caulerpaceae
Caulerpaceae is a family of green algae in the order Bryopsidales Bryopsidales is an order of green algae, in the class Ulvophyceae. Characteristics The thallus is filamentous and much branched and may be packed into a mass. It is coenocytic, having multi-nucleate cells consisting of cytoplasm contained withi .... Caulerpaceae is considered to be a widespread and vital structural component of many Cenozoic-recent reefs. It is estimated to be responsible for approximately 25-30% of CaCO3 in Neogene fossil reefs. References External links Ulvophyceae families {{green algae-stub ...

Surculus
A branch, sometimes called a ramus in botany, is a woody structural member connected to the central trunk of a tree (or sometimes a shrub). Large branches are known as boughs and small branches are known as twigs. The term '' twig'' usually refers to a terminus, while ''bough'' refers only to branches coming directly from the trunk. Due to a broad range of species of trees, branches and twigs can be found in many different shapes and sizes. While branches can be nearly horizontal, vertical, or diagonal, the majority of trees have upwardly diagonal branches. A number of mathematical properties are associated with tree branchings; they are natural examples of fractal patterns in nature, and, as observed by Leonardo da Vinci, their cross-sectional areas closely follow the da Vinci branching rule. Terminology Because of the enormous quantity of branches in the world, there are numerous names in English alone for them. In general however, unspecific words for a branch (su ...

Stipe (botany)
In botany, a stipe is a stalk that supports some other structure. The precise meaning is different depending on which taxonomic group is being described. file:Helicteres-Yucatán-Flowers.jpg, The long stipe of a '' Helicteres'' flower. file:Helicteres-Yucatán-Fruits.jpg, remains as each flower forms a fruit. In the case of ferns, the stipe is only the petiole from the rootstock to the beginning of the leaf tissue, or lamina. The continuation of the structure within the lamina is then termed a rachis. In flowering plants, the term is often used in reference to a stalk that sometimes supports a flower's ovary. In orchids, the stipe or caudicle is the stalk-like support of the pollinia. It is a non-viscid band or strap connecting the pollinia with the viscidium (the viscid part of the rostellum or beak). A stipe is also a structure found in organisms that are studied by botanists but that are no longer classified as plants. It may be the stem-like part of the thallus of a mus ...

Bonin Islands
The Bonin Islands, also known as the , are an archipelago of over 30 subtropical and tropical islands, some directly south of Tokyo, Japan and northwest of Guam. The name "Bonin Islands" comes from the Japanese word ''bunin'' (an archaic reading of ''mujin''), meaning "no people" or "uninhabited". The only inhabited islands of the group are Chichijima (), the seat of the municipal government, and Hahajima (). Archeological evidence has revealed that some of the islands may have been prehistorically inhabited by members of an unknown Micronesian ethnicity. Ogasawara Municipality (''mura'') and Ogasawara Subprefecture take their names from the Ogasawara Group. The is also used as a wider collective term that includes other islands in Ogasawara Municipality, such as the Volcano Islands, along with three other remote islands ( Nishinoshima, Minamitorishima, and Okinotorishima). Geographically speaking, all of these islands are parts of the Nanpō Islands. A total population of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National University Of Ireland
The National University of Ireland (NUI) ( ga, Ollscoil na hÉireann) is a federal university system of ''constituent universities'' (previously called ''university college, constituent colleges'') and ''recognised colleges'' set up under the Irish Universities Act, 1908, and significantly amended by the Universities Act, 1997. The constituent universities are for all essential purposes independent universities, except that the academic degree, degrees and Higher Diploma, diplomas are those of the National University of Ireland with its seat in Dublin. In Post-nominal letters, post-nominals, the abbreviation ''NUI'' is used for degrees from all the constituent universities of the National University of Ireland. History Queen's Colleges at Belfast, Cork (city), Cork, and Galway were established in 1845. In 1849 teaching commenced and a year later they were united under the Queen's University of Ireland. The Catholic University of Ireland was created as an independent univ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caulerpa
''Caulerpa'' is a genus of seaweeds in the family Caulerpaceae (among the green algae). They are unusual because they consist of only one cell with many nuclei, making them among the biggest single cells in the world. A species in the Mediterranean can have a stolon more than long, with up to 200 fronds. This species can be invasive from time to time. Referring to the crawling habit of its thallus, the name means 'stem (that) creeps', from the Ancient Greek ' (, ‘stalk’) and ' (, ‘to creep’). Taxonomy and nomenclature First described by Jean Vincent Lamouroux in 1809, ''Caulerpa'' is the only genus under the family Caulerpaceae, from the order Bryopsidales, class Ulvophyceae, and phylum Chlorophyta. Through the use of ''tuf''A gene sequencing, it was revealed that ''Pseudochlorodesmis'' F. Børgesen was a sister clade of ''Caulerpa''. Cremen et al. proposed a new classification scheme in Bryopsidales, wherein Caulerpaceae and Halimedaceae were described as sister fami ...
