International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. 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 partners ...

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, i ... [...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. 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 families. Species discrimination via morphology-based identification is often hampered by the high degree of variation among traits. Thus, ...

Caulerpa Racemosa
''Caulerpa racemosa'' is a species of edible Green algae, 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. Despite the name, it is not related to grapes. 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 (biology), 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 Phylogeny, phylogenetic relationships. Description A plant of ''C. racemosa'' consists of a number of branches linked to stolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dione Arcuata
''Dione arcuata'', commonly known as eyelash seaweed, is the only species of the red algae genus ''Dione''. The specific name ''arcuata'' comes from Latin and refers to the bow-like curved shape of the algae, while the generic name ''Dione'' is another name for the goddess Venus. It is made of filaments that are around 1.5 centimeters long; they are curved, wide, and do not split into branches. Taxonomy The first collection of the algae was made in 2000, and it was marked as a potential new species. Eyelash seaweed was first analyzed in a 2004 study on the genus '' Bangia''. It was initially called "''Bangia'' sp. BKE" and its genetic dissimilarity to other species in ''Bangia'' was noted. ''Dione arcuata'' was first formally described by Wendy Nelson in 2005, along with the related alga '' Minerva aenigmata''. Nelson split both species from ''Bangia'' based on morphological, habitat, and genetic differences. Ecology Eyelash seaweed is endemic to New Zealand and can be ...

Sargassum Templetonii
''Sargassum'' is a genus of brown macroalgae (seaweed) in the order Fucales of the Phaeophyceae class. 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. The species within Sargassum are normally benthic, but some of the species may take on a planktonic, often pelagic existence after being removed from reefs during rough weather. 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''. The size of annual blooms in the Atlantic ...
