Thalassodendron Ciliatum
''Thalassodendron ciliatum'', the sickle-leaved cymodocea, is a species of plant in the ''Thalassodendron'' genus of seagrasses in the family Cymodoceaceae. Distribution ''Thalassodendron ciliatum'' has a wide distribution throughout the Indo-Pacific region, but has variable abundances throughout its range. This seagrass has been recorded from the western Philippines to Borneo and Singapore, Indonesia, Papua New Guinea, the Caroline Islands, Vanuatu, Australia, India and the Maldives. It is also common from the Gulf of Oman to the Red Sea down to South Africa, Madagascar, the Seychelles, the Comores, the Mascarenes and parts of Malesia and the Solomon Islands.seagrassrecovery.com date of access Wednesday, December 11, 2013 Short, F.T., Coles, R., Waycott, M., Bujang, J.S., Fortes, M., Prathep, A ...

Thalassodendron
''Thalassodendron'' is a genus of seagrass in the family Cymodoceaceae, described as a genus in 1970. It grows along the shores of the Indian Ocean, the western Pacific Ocean and around Australasia. The genus was circumscribed by Cornelis den Hartog in Verh. Kon. Ned. Akad. Wetensch., Afd. Natuurk., Sect. 2, vol.59 (1) on page 186 in 1970. The genus name of '' Thalassodendron'' is named after Thalassa, the Greek word for the 'sea' and for its divine female personification in Greek mythology and ''dendron'' the Greek word for Tree. Species As accepted by Kew; *'' Thalassodendron ciliatum'' - Islands of the Indian Ocean; shores of Africa, Asia, Australia, Micronesia *''Thalassodendron leptocaule'' - Mozambique, KwaZulu-Natal *''Thalassodendron pachyrhizum'' - Western Australia Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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. phylogenetic analysis should c ...

Seagrass
Seagrasses are the only flowering plants which grow in marine environments. There are about 60 species of fully marine seagrasses which belong to four families ( Posidoniaceae, Zosteraceae, Hydrocharitaceae and Cymodoceaceae), all in the order Alismatales (in the clade of monocotyledons). Seagrasses evolved from terrestrial plants which recolonised the ocean 70 to 100 million years ago. The name ''seagrass'' stems from the many species with long and narrow leaves, which grow by rhizome extension and often spread across large " meadows" resembling grassland; many species superficially resemble terrestrial grasses of the family Poaceae. Like all autotrophic plants, seagrasses photosynthesize, in the submerged photic zone, and most occur in shallow and sheltered coastal waters anchored in sand or mud bottoms. Most species undergo submarine pollination and complete their life cycle underwater. While it was previously believed this pollination was carried out without p ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Cymodoceaceae
Cymodoceaceae is a family of flowering plants, sometimes known as the "manatee-grass family", which includes only marine species. The 2016 APG IV does recognize Cymodoceaceae and places it in the order Alismatales, in the clade monocots. The family includes five genera, totaling 17 species occurring in tropical seas and oceans (so-called seagrasses). According to thAP-Websiteit is doubtful if the family Ruppiaceae is distinct enough to be kept apart. The inclusion of the sole genus ''Ruppia'' in Ruppiaceae in Cymodoceaceae is being considered. The plants in the three families Cymodoceaceae, Posidoniaceae and Ruppiaceae form a monophyletic group. Its fossil record shows that Cymodoceaceae was established in its current Indo-West Pacific distribution by the early Eocene and perhaps even during the late Paleocene. Fossils of ''Thalassodendron auriculalopris'' den Hartog and ''Cymodocea floridana'' den Hartog (both extant) were also found in west-central Florida and date back to ...

Seaweed Farming
Seaweed farming or kelp farming is the practice of cultivating and harvesting seaweed. In its simplest form, it consists of the management of naturally found batches. In its most advanced form, it consists of fully controlling the life cycle of the algae. The top seven most cultivated seaweed taxa are '' Eucheuma'' spp., '' Kappaphycus alvarezii'', '' Gracilaria'' spp., ''Saccharina japonica'', '' Undaria pinnatifida'', '' Pyropia'' spp., and ''Sargassum fusiforme''. ''Eucheuma'' and ''K. alvarezii'' are farmed for carrageenan (a gelling agent); ''Gracilaria'' is farmed for agar; while the rest are farmed for food. The largest seaweed-producing countries are China, Indonesia, and the Philippines. Other notable producers include South Korea, North Korea, Japan, Malaysia, and Zanzibar (Tanzania). Seaweed farming has frequently been developed as an alternative to improve economic conditions and to reduce fishing pressure and overexploited fisheries. Global production of farmed a ...
