Durvillaea
''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 Pa ...

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.

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, ...

Durvillaea Willana
''Durvillaea willana'' is a large species of Durvillaea, southern bull kelp Endemism, endemic to New Zealand. Etymology The species epithet, ''willana'', honours Eileen Alice Willa who collected many algal species for Lindauer. Description This species is chocolate brown in colour and is darker than all other bull kelp species. It has a branched stipe. The species is non-buoyant and does not have 'honeycomb' in its fronds. The holdfast becomes large and spreads like a plate on rocky substrates. This species is superficially similar in appearance to ''Durvillaea antarctica''. However, ''D. willana'' has smaller blades than ''D. antarctica'' and is usually found lower on the shoreline because its lower tolerance of wave action comparded ''D. antarctica''. It also has a branched stipe and does not have buoyant fronds, unlike ''D. antarctica''. Distribution This species of kelp is endemic to New Zealand and is found on the southeastern shores of the North Island, although not in ...

Chilean Cuisine
Chilean cuisine stems mainly from the combination of traditional Spanish cuisine, Chilean Mapuche culture and local ingredients, with later important influences from other European cuisines, particularly from Germany, the United Kingdom and France. The food tradition and recipes in Chile are notable for the variety of flavours and ingredients, with the country's diverse geography and climate hosting a wide range of agricultural produce, fruits and vegetables. The long coastline and the peoples' relationship with the Pacific Ocean add an immense array of seafood to Chilean cuisine, with the country's waters home to unique species of fish, molluscs, crustaceans and algae, thanks to the oxygen-rich water carried in by the Humboldt Current. Chile is also one of the world's largest producers of wine and many Chilean recipes are enhanced and accompanied by local wines. The confection dulce de leche was invented in Chile and is one of the country's most notable contributions to worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Nereocystis Luetkeana
''Nereocystis'' (Greek, 'mermaid's bladder') is a monotypic genus of subtidal kelp containing the species ''Nereocystis luetkeana''. Some English names include edible kelp, bull kelp, bullwhip kelp, ribbon kelp, bladder wrack, and variations of these names. Due to the English name, bull kelp can be confused with southern bull kelps, which are found in the Southern Hemisphere. ''Nereocystis luetkeana'' forms thick beds on subtidal rocks, and is an important part of kelp forests. Etymology The species ''Nereocystis luetkeana'' was named (as ''Fucus luetkeanus'') after the German-Russian explorer Fyodor Petrovich Litke (also spelled Lütke) by Mertens. The species was renamed in a description by Postels and Ruprecht. Description Individuals can grow to a maximum of . ''Nereocystis'' has a holdfast of about , and a single stipe, topped with a pneumatocyst containing carbon monoxide, from which sprout the numerous (about 30-64) blades. The blades may be up to long, and up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tautuku Peninsula
Tautuku Peninsula is a rocky headland in the Catlins on the south coast of Otago on the South Island of New Zealand. It is located 25 km (15 mi) east of Waikawa, at the western end of Tautuku Bay. From 1839 to 1846, a whaling station was sited near the peninsula's neck, and a port was later developed for the fishing, flax and timber industries. When these industries declined, the port was closed. Today, southern right whales are making slow come back and still can be seen around the peninsula occasionally. New Zealand sea lions and yellow-eyed penguins (''hoiho'') also can be seen on beaches. Sporadic mammal visitors include leopard seals. The estuary of the Tautuku River, just north of the peninsula, is inhabited by fernbirds.

Kelp
Kelps are large brown algae seaweeds that make up the order Laminariales. There are about 30 different genera. Despite its appearance, kelp is not a plant - it is a heterokont, a completely unrelated group of organisms. Kelp grows in "underwater forests" (kelp forests) in shallow oceans, and is thought to have appeared in the Miocene, 5 to 23 million years ago. The organisms require nutrient-rich water with temperatures between . They are known for their high growth rate—the genera ''Macrocystis'' and '' Nereocystis'' can grow as fast as half a metre a day, ultimately reaching .Thomas, D. 2002. ''Seaweeds.'' The Natural History Museum, London, p. 15. Through the 19th century, the word "kelp" was closely associated with seaweeds that could be burned to obtain soda ash (primarily sodium carbonate). The seaweeds used included species from both the orders Laminariales and Fucales. The word "kelp" was also used directly to refer to these processed ashes. Description In most kelp ...

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 ...

Enderby Island
Enderby Island is part of New Zealand's uninhabited Auckland Islands archipelago, south of mainland New Zealand. It is situated just off the northern tip of Auckland Island, the largest island in the archipelago. Geography and geology Enderby Island lies off the northeastern extremity of Auckland Island, directly across from the mouth of Port Ross, from which it is separated by some . Several islands lie in the strait between the two islands, notably Rose, Ewing, and Ocean Islands. Of these, Rose Island lies between the two closest points on Auckland and Enderby Island, separated from them by two narrow channels, each some in width. The island comprises around 1% of the total land area of the Auckland island group. Enderby Island has few notable geographic features. It is surrounded by cliffs and rocky shorelines, with the only landing point being at Sandy Bay in the island's southwest. Several historic huts are located at this bay, which is also home to a breeding colony of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
