Durvillaea Potatorum
''Durvillaea potatorum'' is a large, robust species of southern bull kelp found in Australia. Description The species can be confused with '' Durvillaea amatheiae'', which has an overlapping geographic distribution. ''D. potatorum'' has a shorter, wider stipe with more limited lateral blade development, whereas ''D. amatheiae'' has a shorter, narrow stipe and typically prolific lateral blade development. Distribution ''Durvillaea potatorum'' is endemic to southeast Australia. Uses ''Durvillaea potatorum'' was used extensively for clothing and tools by Aboriginal Tasmanians, with uses including material for shoes and bags to transport freshwater and food. Currently, ''D. potatorum'' is collected as beach wrack from King Island, where it is then dried as chips and sent to Scotland for phycocolloid {{Short pages monitor [Baidu] |
Eaglehawk Neck
Eaglehawk Neck, officially Teralina / Eaglehawk Neck, is a narrow isthmus that connects the Tasman Peninsula with the Forestier Peninsula, and hence to mainland Tasmania, Australia. The locality of Eaglehawk Neck is in the local government area of Tasman in the South-east region of Tasmania. The locality is about north-east of the town of Nubeena. At the , the settlement of Eaglehawk Neck had a population of 385. Location and features Locally known as "the Neck", the isthmus itself is around long and under wide at its narrowest point. The area features rugged terrain and several unusual geological formations. These include the Tessellated Pavement, an area of flat rock that looks to be manmade but is in fact formed by erosion. A short walk further via Lufra Cove leads to Clyde Island, accessible for crossings at low tide, which sits at the northern entry to Pirates Bay. The island hosts two grave sites, and a rumbling blow hole cleaves the island. Eaglehawk Neck is a wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacques Labillardière
Jacques-Julien Houtou de Labillardière (28 October 1755 – 8 January 1834) was a French biologist noted for his descriptions of the flora of Australia. Labillardière was a member of a voyage in search of the Jean-François de Galaup, comte de Lapérouse, La Pérouse expedition. He published a popular account of his journey and produced the first Flora (publication), Flora on the region. Early life Jacques Labillardière was born in Alençon, Normandy, France, on 28 October 1755. The ninth of 14 children of a lace merchant, he was born into a devoutly Roman Catholic family of modest means.Duyker (2003) p. 8. The surname ''Labillardière'' originated with Labillardière's grandfather, Jacques Houtou, who, in an affectation of nobility, appended the name of the family's estate, ''La Billardière'', after his surname. Labillardière was thus baptised under the surname ''Houtou de Labillardière'', but he later dropped the patronymic, retaining only ''Labillardière'' in both h ...

Johan Erhard Areschoug
Johan Erhard Areschoug (Johannes Erhard Areschoug, Philos. Doctor, Botanices et Oeconomiae) (16 September 1811 – 7 May 1887) was a Swedish botanist who was a native of Göteborg. He was a member of the Arreskow family (in Swedish). His first name is sometimes recorded as "John". He studied natural sciences at the University of Lund, where in 1838 he earned his doctorate in philosophy. In 1859 he succeeded Elias Magnus Fries (1794-1878) as professor of botany at the University of Uppsala, a position he maintained until 1876. In 1851, he was elected a member of the Royal Swedish Academy of Sciences. Areschoug performed extensive field studies of Scandinavian cryptogams, being remembered for his work in the field of phycology. The red algae Red algae, or Rhodophyta (, ; ), are one of the oldest groups of eukaryotic algae.

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 ...

Aboriginal Tasmanians
The Aboriginal Tasmanians (Palawa kani: ''Palawa'' or ''Pakana'') are the Aboriginal people of the Australian island of Tasmania, located south of the mainland. For much of the 20th century, the Tasmanian Aboriginal people were widely, and erroneously, thought of as being an extinct cultural and ethnic group that had been intentionally exterminated by white settlers. Contemporary figures (2016) for the number of people of Tasmanian Aboriginal descent vary according to the criteria used to determine this identity, ranging from 6,000 to over 23,000. First arriving in Tasmania (then a peninsula of Australia) around 40,000 years ago, the ancestors of the Aboriginal Tasmanians were cut off from the Australian mainland by rising sea levels c. 6000 BC. They were entirely isolated from the outside world for 8,000 years until European contact. Before British colonisation of Tasmania in 1803, there were an estimated 3,000–15,000 Palawa. The Palawa population suffered a drastic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrack (seaweed)
Wrack is part of the common names of several species of seaweed in the family Fucaceae. It may also refer more generally to any seaweeds or seagrasses that wash up on beaches and may accumulate in the wrack zone. It consists largely of species of ''Fucus'' — brown seaweeds with flat branched ribbon-like fronds, characterized in '' F. serratus'' by a saw-toothed margin and in '' F. vesiculosus'', another common species, by bearing air-bladders. Another component of sea wrack may be seagrasses such as ''Zostera marina'' a marine flowering plant with bright green long narrow grass-like leaves. ''Posidonia australis'', which occurs sub-tidally on the southern coasts of Australia, sheds its older ribbon-like leaf blades in winter, resulting in thick accumulations along more sheltered shorelines. *"Bladder wrack", ''Fucus vesiculosus'' *"Channelled wrack", ''Pelvetia canaliculata'' *"Knotted wrack", ''Ascophyllum nodosum'' *"Spiral wrack" or "flat wrack", ''Fucus spiralis'' *"Toot ...

King Island (Tasmania)
King Island is an island in the Bass Strait, belonging to the Australian state of Tasmania. It is the largest of three islands known as the New Year Group, and the second-largest island in Bass Strait (after Flinders Island). The island's population at the was 1,585 people, up from 1,566 in 2011. The local government area of the island is the King Island Council. The island forms part of the official land divide between the Great Australian Bight and Bass Strait, off the north-western tip of Tasmania and about halfway to the mainland state of Victoria. The southernmost point is Stokes Point and the northernmost point is Cape Wickham. There are three small islands immediately offshore: New Year Island and Christmas Island situated to the northwest, and a smaller island Councillor Island to the east, opposite Sea Elephant Beach. King Island was first visited by Europeans in the late 18th century. It was named after Philip Gidley King, Colonial Governor of New South Wales, who ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...
