International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caulerpa Webbiana
''Caulerpa webbiana'', commonly known as bottlebrush green seaweed, is a species of seaweed in the family ''Caulerpaceae''. The seaweed has an olive green to bright green thallus that spreads outward to around forming dense clumps on coral rubble among seagrasses. The stems are about in length and have small bristles composed of many fine branched filaments, that are arranged in whorls around the stolon in the middle so that it resembles a stiff bottlebrush. The species was first formally described in 1837 by the botanist Camille Montagne as part of the work ''Centurie de plantes cellulaires exotiques nouvelles'' as published in ''Annales des Sciences Naturelles, Botanique, Seconde série''. The only known synonym is ''Chauvinia webbiana'' as described by Friedrich Traugott Kützing in 1849. The type specimen was collected from around Lanzarote in the Canary Islands. The species is found in warmer waters in sediment or in coral reefs. It is found around the Canary Islands, isl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caulerpa Sertulariodes
''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 ...

Caulerpa Racemosa
''Caulerpa racemosa'' is a species of edible green alga, a seaweed in the family Caulerpaceae. It is commonly known as sea grapes (along with the related ''Caulerpa lentillifera'') and is found in many areas of shallow sea around the world. There are a number of different forms and varieties, and one that appeared in the Mediterranean Sea in 1990, which is giving cause for concern as an invasive species. Taxonomy There are about 75 species of ''Caulerpa''. Many of them exhibit polymorphism, showing different growth forms in different habitats which makes them difficult to identify. ''C. racemosa'', ''C. laetevirens'' and ''C. peltata'' form a species complex. A number of forms and varieties for ''C. racemosa'' are listed but further study is needed to clarify their exact phylogenetic relationships. Description A plant of ''C. racemosa'' consists of a number of branches linked to stolons which are anchored to the sandy substrate by rhizoids. The branches are a few centimetres ...

Sargassum Templetonii
''Sargassum'' is a genus of brown (class Phaeophyceae) macroalgae (seaweed) in the order Fucales. Numerous species are distributed throughout the temperate and tropical oceans of the world, where they generally inhabit shallow water and coral reefs, and the genus is widely known for its planktonic (free-floating) species. Most species within the class Phaeophyceae are predominantly cold-water organisms that benefit from nutrients upwelling, but the genus ''Sargassum'' appears to be an exception. Any number of the normally benthic species may take on a planktonic, often pelagic existence after being removed from reefs during rough weather; however, two species (''S. natans'' and ''S. fluitans'') have become holopelagic—reproducing vegetatively and never attaching to the seafloor during their lifecycles. The Atlantic Ocean's Sargasso Sea was named after the algae, as it hosts a large amount of ''Sargassum''. History ''Sargassum'' was named by the Portuguese sailors who found it i ...
