Durvillaeales
''Durvillaea'' is a genus of large brown algae in the monotypic family Durvillaeaceae. All members of the genus are found in the southern hemisphere, including Australia, New Zealand, South America, and various subantarctic islands. ''Durvillaea'', commonly known as southern bull kelps, occur on rocky, wave-exposed shorelines and provide a habitat for numerous intertidal organisms. Many species exhibit a honeycomb-like structure in their fronds that provides buoyancy, which allows individuals detached from substrates to raft alive at sea, permitting dispersal for hundreds of days over thousands of kilometres. ''Durvillaea'' species have been used for clothing, tools and as a food source by many indigenous cultures throughout the South Pacific, and they continue to play a prominent role in Chilean cuisine. Common name and etymology The common name for ''Durvillaea'' is southern bull kelp, although this is often shortened to bull kelp, which can generate confusion with the North ...

Durvillaea Antarctica
''Durvillaea antarctica'', also known as ' and ', is a large, robust species of southern bull kelp found on the coasts of Chile, southern New Zealand, and Macquarie Island.Smith, J.M.B. and Bayliss-Smith, T.P.

''D. antarctica'', an alga, does not have air bladders, but floats due to a unique honeycomb structure within the alga's blades, which also helps the kelp avoid being damaged by the strong waves.Maggy WassilieffSeaweed - Bull kelp’s honeycombed structure ''Te Ara - the Encyclopedia of New Zealand'', Ministry of Culture and Heritage.

Brown Algae
Brown algae (singular: alga), comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. They are dominant on rocky shores throughout cooler areas of the world. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat. For instance, ''Macrocystis'', a kelp of the order Laminariales, may reach in length and forms prominent underwater kelp forests. Kelp forests like these contain a high level of biodiversity. Another example is ''Sargassum'', which creates unique floating mats of seaweed in the tropical waters of the Sargasso Sea that serve as the habitats for many species. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class, such as kelps, are used by humans as food. Between 1,500 and ...

Durvillaea Poha
''Durvillaea poha'' is a large, robust species of southern bull kelp found in New Zealand. Discovery The species was previously classified as the "cape" lineage of ''Durvillaea antarctica'', but in 2012 it was recognised as a distinct species due to consistent genetic, morphological and ecological differences. In southern New Zealand, ''D. poha'' and ''D. antarctica'' frequently grow next to one another, although ''D. poha'' normally grows higher up or further back on rock platforms, or in more sheltered bays, where wave force is weaker. ''D. poha'' generally has wider fronds than ''D. antarctica'', and can appear more 'orange' across the frond area. Mitochondrial introgression has been observed between the two species, where some plants in Wellington exhibited the nuclear DNA of ''D. poha'' but also mitochondrial DNA belonging to ''D. antarctica''. Etymology The specific epithet is from pōhā, storage bags made by Māori out of kelp fronds. Description The species has wide, ...

Paul Auguste Hariot
Paul Auguste Hariot (1854 – 5 July 1917), the son of Louis Hariot (also a pharmacist), was a French pharmacist and noted phycologist, best known for his 1900 publicatio''Atlas Colorié des Plantes Médicinales Indigènes'' Hariot took up the position of botanical assistant at the ''École Supérieure de Pharmacie'' in the late 1870s during his training in pharmacy in Paris. On qualifying in 1882, his rather quiet and studious life was changed by an invitation to accompany the botanist Émile Bescherelle (1828-1903) on an expedition to Cape Horn aboard the ship ''La Romanche'', a trip during which he amassed a fine collection of algae. On returning to France he studied natural sciences and was awarded a degree in 1888 whereupon he joined the National Museum of Natural History in Paris, working in the cryptogamic herbarium under Professor van Tieghem. Here he worked on classifying specimens that had been gathered by Sébastien Vaillant (1669-1722), and those of the brothers Edmon ...

Gribble
A gribble /ˈgɹɪbəl/ (or gribble worm) is any of about 56 species of marine isopod from the family Limnoriidae. They are mostly pale white and small ( long) crustaceans, although ''Limnoria stephenseni'' from subantarctic waters can reach . Classification The term "gribble" was originally assigned to the wood-boring species, especially the first species described from Norway by Jens Rathke in 1799, '' Limnoria lignorum''. The Limnoriidae are now known to include seaweed and seagrass borers, as well as wood borers. Those gribbles able to bore into living marine plants are thought to have evolved from a wood (dead plant) boring species. Ecology Gribbles bore into wood and plant material for ingestion as food. The cellulose of wood is digested, most likely with the aid of cellulases produced by the gribbles themselves. The most destructive species are ''Limnoria lignorum'', ''L. tripunctata'' and ''L. quadripunctata''. Due to dispersal while inhabiting wooden ships, it is uncert ...

Crustacea
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by ...

Fauna
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is '' funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
