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 The Bonin Islands, also known as the , is a list of islands of Japan, Japanese archip ...

He is the author of important studies about seaweed Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of ''Rhodophyta'' (red), '' Phaeophyta'' (brown) and ''Chlorophyta'' (green) macroalgae. Seaweed species such as ...s.

Caulerpaceae
Caulerpaceae is a family of green algae in the order Bryopsidales Bryopsidales is an order of green algae, in the class Ulvophyceae. It is a diverse group of mostly marine macroalgae. Characteristics The thallus is filamentous, highly branched, and may be packed into a mass. It is coenocytic, having multi-nu .... 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 Ulvophyceae families {{Ulvophyceae-stub ...

Surculus
A branch, also called a ramus in botany, is a stem that grows off from another stem, or when structures like veins in leaves are divided into smaller veins. History and etymology In Old English, there are numerous words for branch, including , , , and . There are also numerous descriptive words, such as (that is, something that has bled, or 'bloomed', out), (literally 'little bough'), (literally 'on growth'), and (literally 'offspringing'). Numerous other words for twigs and boughs abound, including , which still survives as the ''-toe'' in ''mistletoe''. Latin words for branch are or . The latter term is an affix found in other modern words such as ''cladodont'' (prehistoric sharks with branched teeth), ''cladode'' (flattened leaf-like branches), or ''cladogram'' (a branched diagram showing relations among organisms). Woody branches Large branches are known as boughs and small branches are known as twigs. The term ''twig'' usually refers to a terminus, while ''bough' ...

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 ...

Bonin Islands
The Bonin Islands, also known as the , is a list of islands of Japan, Japanese archipelago of over 30 subtropical and Island#Tropical islands, tropical islands located around SSE of Tokyo and northwest of Guam. The group as a whole has a total area of but only two of the islands are permanently inhabited, Chichijima and Hahajima. Together, their population was 2,560 as of 2021. Administratively, Tokyo Metropolitan Government, Tokyo's Ogasawara Subprefecture also includes the settlements on the Volcano Islands and the Japan Maritime Self-Defense Force, Self-Defense Force post on Iwo Jima. The seat of government is Chichijima. Because of the Bonins' isolation, many of their animals and plants have undergone unique evolutionary processes. It has been called "the Galápagos Islands, Galápagos of the Orient" and was named a natural World Heritage Site in 2011. When first reached during the early modern period, the islands were entirely uninhabited. Subsequent research has found ev ...

National University Of Ireland
The National University of Ireland (NUI) () is a federal university system of ''constituent universities'' (previously called '' 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 degrees and diplomas are those of the National University of Ireland with its seat in Dublin. In 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, 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 university on 3 November 1854 for the education of Catholics; that university was not a recognised university ...

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 cell nucleus, nuclei, making them among the biggest single cells in the world. Referring to the crawling growth habit#Structure, 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 families. Species discrimination via morphology-based identification is often hampered by the high degr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
