Durvillaea antarctica (Chamisso) Hariot, 1892 bull kelp Native range | All suitable habitat | Point map | Year 2100: This map was computer-generated and has not yet been reviewed. The coastline at this point is very exposed to wave action and one of the dominant features … Laing) W.A. [3][5] Notably, additional unclassified lineages were estimated within D. [38] Exclusive harvest rights are designated using coves or caletas, and the income for fishers (and their unions) often depends upon the sale of cochayuyo. Durvillaea antarctica National Institutes of Health Create Alert. Durvillaea antarctica is a large, robust bull kelp species and the dominant seaweed in southern New Zealand and Chile. Much of the available data are for the species Durvillaea antarctica, D. willana, and D. potatorum. in a way that maintains its nutritional properties, such as iodine, minerals, fiber, proteins, and also has all the essential amino acids. Bei der Durvillea antarctica handelt es sich um eine widerstandsfähige Großalge mit einem kräftigen Cauloid (Stiel)[2]. South. [3][5], D. potatorum was used extensively for clothing and tools by Aboriginal Tasmanians, with uses including material for shoes and bags to transport freshwater and food. Gel electrophoresis showed that the acidic polysaccharide (23.5% sulfate, 4.5% uronic acid) was not homogeneous. Durvillaea antarctica Taxonomy ID: 112057 (for references in articles please use NCBI:txid112057) current name. [39][40] The Ngai Tahu Claims Settlement Act 1998 protects Durvillaea bull kelp from commercial harvesting within the tribe's traditional seaweed-gathering areas.[42]. [3][37] The same species is also called cochayuyo (cocha: lake, and yuyo: weed), and hulte in Quechua. Phylogeographic analyses using mitochondrial COX1 sequence data and genotyping by sequencing data for thousands of anonymous nuclear loci, indicate that a historic uplift event (800 – 1400 years before present) along the fault zone and subsequent recolonisation, has left a lasting impact upon the genetic diversity of the intertidal species D. antarctica and D. poha, but not on the subtidal species D. Taken together, these findings suggest that these algae extracts may be potential … Durvillaea antarctica From Wikipedia, the free encyclopedia Durvillaea poha (recently split as a new species from D. antarctica ) stipes on Second Bay, Otago, New Zealand Die Gattung wurde zu Ehren von Jules Dumont d’Urville benannt.

[6], Durvillaea species are characterised by their prolific growth and plastic morphology. [3][9] In contrast, species as D. willana lack such 'honeycomb' tissue and are non-buoyant, preventing the plants from moving long distances. The drying characteristics of edible seaweed Durvillaea antarctica subjected to hot‐air drying at 40, 50, 60, 70, and 80°C were investigated. The genus is named after French explorer Jules Dumont d'Urville (1790-1842). [36], D. antarctica and D. incurvata have been used in Chilean cuisine for salads and stews, predominantly by the Mapuche indigenous people who refer to it as collofe or kollof. However, the relationship between benthic populations and stranded seaweeds has received little attention. Exporter. Durvillaea antarctica, allgemein bekannt als Cochayuyo, ist eine große, robuste Stier Seetang - Arten und die dominanten Algen im südlichen Neuseeland und Chile. [25], It has been hypothesised that gaps in the current geographic range of D. willana around Wellington and the Wairarapa may have been caused by local extinction following historic earthquake uplift events such as the 1855 Wairarapa earthquake. the nutritional value of the Ulva lactuca and Durvillaea antarctica species which represent natural resources with potential economic value for use in human and animal nutrition. [12][13][14], Specimens of Durvillaea can detach from substrates, particularly during storms. Semantic Scholar uses AI to extract papers important to this topic. [34][35] Currently, D. potatorum is collected as beach wrack from King Island, where it is then dried as chips and sent to Scotland for phycocolloid extraction. New Zealand Bull Kelp Durvillaea antarctica. Zur Navigation springen Zur Suche springen. Certifications. Kelp-associated invertebrates can be transported inside of drifting kelp holdfasts, potentially leading to long-distance dispersal and a significant impact upon the population genetic structure of the invertebrate species. 2. In this work Ni(II) and Cr(III) adsorption on Durvillaea antarctica surface were studied, optimal condition of pH, adsorption time is achieved at pH 5.0, with contact times of 240 and 420 minutes for a maximum adsorption capacity of 32.85 and 102.72 mg g–1 for Ni(II) and Cr(III), respectively.

durvillaea antarctica uses

[26] This uplift caused large scale die offs of D. antarctica and dramatically affected the intertidal community. Durvillaea antarctica hat wie alle Arten der Gattung einen diplontischen Lebenszyklus ohne einen Generationswechsel. Durvillaea antarctica . antarctica. Beachcast, decomposing bull-kelp is colonised and consumed by a wide variety of invertebrates including sandhoppers Bellorchestia quoyana,[20] and kelp flies Chaetocoelopa littoralis. [12][13][14], Holdfasts of D. antarctica and other species are often inhabited by a diverse array of epifaunal invertebrates, many of which burrow into and graze on the kelp. Materials and methods 2.1. 2019. Nelson 2003.[18][19]. [10][28], A substantial die off of Durvillaea bull kelp occurred along the Kaikōura coastline following the 2016 Kaikōura earthquake, which caused uplift up to 6 metres. Durvillaea is a genus of brown algae in the monotypic family Durvillaeaceae.All members of the genus are found in the southern hemisphere, particularly New Zealand, South America, Australia and various subantarctic islands. A time-calibrated phylogeny of Durvillaea based on four mitochondrial and nuclear DNA markers (COI, rbcL, 28S and 18S) indicates the evolutionary relationships shown in the cladogram below. Die Spermatozoiden sind heterokont begeißelt und werden durch das Pheromon Hormosirene von den Eizellen angelockt. [15] In New Zealand, epifaunal species include the sea-star Anasterias suteri, crustaceans Parawaldeckia kidderi, P. karaka, Limnoria segnis and L. stephenseni, and the molluscs Cantharidus roseus, Onchidella marginata, Onithochiton neglectus, and Sypharochiton sinclairi. [3][8] When these species detach from the seabed, this buoyancy allows for plants to drift for substantial distances, permitting long distance dispersal. Christiaan van den Hoek, David Mann und M. Jahns: https://de.wikipedia.org/w/index.php?title=Durvillaea_antarctica&oldid=193664922, Lebewesen in menschlicher Nutzung und Haltung, „Creative Commons Attribution/Share Alike“. Es werden durch eine Meiose unbewegliche Eizellen und bewegliche Spermatozoiden gebildet (Oogamie). [1] It is found on exposed shores, especially in the northern parts of its range, and attaches itself with a strong holdfast. No drawings available for this family. [2][3], The common name for Durvillaea is southern bull kelp, although this is often shortened to bull kelp, which can generate confusion with the North Pacific kelp species Nereocystis luetkeana. [22] Once the kelp was extirpated, the invasive kelp Undaria pinnatifida recruited in high densities. Durvillaea antarctica hat wie alle Arten der Gattung einen diplontischen Lebenszyklus ohne einen Generationswechsel. overview; data; media; articles; maps; names 2019. growth and includes data on the use of Durvillaea antarctica holdfasts, spider density, seasonal changes in population structure, and growth per moult for juveniles and adults. [16][17] Based on genetic evidence, H. durvillaeae also seems to have also been be transmitted via rafting. Bory de Saint-Vincent, J.B.G.M. [7], Two species, D. antarctica and D. poha are buoyant due to a honeycomb-like structure in the fronds of the kelp that holds air. In this work Ni(II) and Cr(III) adsorption on Durvillaea antarctica surface were studied, optimal condition of pH, adsorption time is achieved at pH 5.0, with contact times of 240 and 420 minutes for a maximum adsorption capacity of 32.85 and 102.72 mg g –1 for Ni(II) and Cr(III), respectively. The POPs Regulation bans or severely restricts the production and use of persistent organic pollutants in the European Union. The common name for Durvillaea is southern bull kelp, although this is often shortened to bull kelp, which can generate confusion with the North Pacific kelp species Nereocystis luetkeana. Der Artname D. antarctica ist irreführend, da sie nicht in der antarktischen Region vorkommt. The techniques used in harvesting and the human uses of Durvillaea spp. Cladophora crispata) by a local population of Titicaca lake border in Peru ( Canales, Taquila, Pacheco, Salas, & Aguilar, 2008 ). willana.

Das Rhizoid (Wurzel) ist ebenfalls gut ausgebildet und mit einem enormen Haftungsvermögen versehen. Sorry! Dadurch und durch das massive Haftorgan bekommt die Alge eine enorme Widerstandskraft gegen starke Wellen und Brandung. Evaluation of the algae extracts as topical formulations in an animal model of HSV-1 skin infection significantly reduced the severity of the disease, more than acyclovir, as well as the duration of the herpetic lesions when compared to mock-treated animals with the Durvillaea antarctica extract performing best. [25], Intertidal species of Durvillaea can be used to estimate earthquake uplift height, with comparable results to traditional methods such as lidar. David R. Schiel; Oecologia; 2019; Corpus ID: 108292578 . Durvillaea Antarctica dehydrated cut tube Agriculture and Live Animals Durvillaea Antarctica "Cochayuyo" dehydrated elaborated and packed in bags of 15 kg. [4], Die Verbreitung reicht nördlich von 29° S in Chile über die subantarktischen Inseln bis Neuseeland.[5]. Once detached, buoyant species such as D. antarctica and D. poha can float as rafts, and can travel vast distances at sea, driven by ocean currents. Durvillaea antarctica surface were studied, optimal condition of pH, adsorption time is achieved at pH 5.0, with contact times of 240 and 420 minutes for a maximum adsorption capacity of 32.85 and 102.72 mg g−1 for Ni(II) and Cr(III), respectively. Global Biodiversity Information Facility. Available for marketplace users Contact. [39][40][41] Pōhā are especially associated with Ngāi Tahu and are often used to carry and store muttonbird (tītī) chicks. Long-term persistence of the floating bull kelp Durvillaea antarctica from the South-East Pacific: Potential contribution to local and transoceanic connectivity. [9] However, uplift along the Akatore fault zone does not appear to have significantly affected the genetic diversity of D. willana in that region, which suggests that earthquake uplift may be insufficient to cause the complete extirpation of this subtidal species.[10]. [3][27][38] The kelp harvest, complemented with shellfish gathering, supports artisanal fishing communities in Chile. METHODS Our study area was at Kean Point, Kaikoura (42°25' 35"S, 173°43'15"E) which is located on the Kai-koura Peninsula. The alga was lying on a shore in Punta Talca, Chile. Just like other algae, it also contains almost all ingredients in a varying amount such as polysaccharide, amino acid, fatty acid, minerals, vitamins, carotenoids, etc. Die Gattung wurde zu Ehren von Jules Dumont d’Urville benannt. Edible seaweed, or sea vegetables, are algae that can be eaten and used in the preparation of food. [4][5], The genus is named after French explorer Jules Dumont d'Urville (1790-1842). Floating seaweeds are important dispersal vectors in marine ecosystems. Durvillaea Antarctica is a kind of natural wild brown seaweed with rich nutrition and delicious taste,it is one of the most precious deep sea plants It contains lot of nutrition include calcium,iodine,iron,potassium,fiber,carotene etc,which is great essential to human,it is one of the most nutritious and healthy food Date: 25 June 2012: Source: Own work: Author: Silk666: Licensing . Durvillaea antarctica, also known as cochayuyo and rimurapa , is a large, robust species of southern bull kelp found on the coasts of Chile, southern New Zealand, and Macquarie Island. [1] All species are restricted to the Southern Hemisphere and many taxa are endemic to particular coastlines or subantarctic islands. It is native to southern New Zealand and Chile and in fact considered dominant seaweed, with a honeycomb-like structure from within. Durvillaea is a genus of brown algae in the monotypic family Durvillaeaceae. Desorption isotherm was performed to estimate the equilibrium moisture content. [21], A marine heatwave in the summer of 2017/18 appears to have caused the local extinction of multiple Durvillaea species at Pile Bay, on the Banks Peninsula. Durvillaea Antarctica is robust and large kelp, also called bull kelp. Sie erreicht eine Länge von bis zu 10 Meter[1]. [7] D. antarctica and D. poha are intertidal, whereas D. willana is subtidal (to 6 m depths). 2019. [26] The damage to infrastructure and ecological disturbance caused by the earthquake was assessed to be particularly damaging for seaweed gatherers and cochayuyo harvest. Durvillea antarctica, auch Cochayuyo oder Bull Kelp genannt, ist eine große Seetangart der Braunalgen aus dem subantarktischen Küstenbereich. Semantic Scholar uses AI to extract papers important to this topic. Aus Wikimedia Commons, dem freien Medienarchiv. Nach der Befruchtung wird sofort wieder eine diploide Alge gebildet. (1826). Free and Open Access to Biodiversity Data. Die Spermatozoiden sind heterokont begeißelt und werden durch das Pheromon Hormosirene von den Eizellen angelockt. The effect of drying temperatures on the proximate composition in this seaweed was also evaluated. D. antarctica has a circumpolar distribution between the latitudes of 29°S (in Chile) and 55°S (on Macquarie Island). [12][13][14], Fronds of D. antarctica can be infected by an endophytic, phaeophycean algal parasite Herpodiscus durvillaeae (Lindauer) G.R.

López, +5 authors M. Thiel; Marine environmental research ; 2019; Corpus ID: 173993590. Durvillaea Antarctica Agriculture and Live Animals. Increased temperatures and heatwaves, increased sedimentation, and invasive species (such as Undaria pinnatifida) are sources of physiological stress and disturbance for members of the genus. All members of the genus are found in the southern hemisphere, including Australia, New Zealand, South America, and various subantarctic islands. There are currently eight recognised species within the genus, and the type species is D. Es werden durch eine Meiose unbewegliche Eizellen und bewegliche Spermatozoiden gebildet . Im Phylloid befinden sich Luftkammern, die Honigwaben ähneln[3]. [23][24] Once an area is cleared of Durvillaea following an uplift event, the bull kelp that re-colonises the area can potentially originate from genetically distinct populations far outside the uplift zone, spread via long distance-dispersal. Der Artname D. antarctica ist irreführend, da sie nicht in der antarktischen Region vorkommt. [11] However, since Durvillaea holdfasts often grow at the uppermost limit of the intertidal zone, these uplift estimates are slightly less accurate compared to measures derived from other intertidal kelp such as Carpophyllum maschalocarpum. [10] Intertidal species can grow at the uppermost limit of the intertidal zone if there is sufficient wave wash.[11] Species can withstand a high level of disturbance from wave action,[7] although storms can remove plants from substrates. [9], Durvillaea bull kelp grow within intertidal and shallow subtidal areas, typically on rocky wave-exposed coastal sites. [23][24] Genetic analysis indicated that some of the Durvillaea that subsequently reached the affected coastline came from areas >1,200 kilometres away. antarctica. Sie erreicht eine Länge von bis zu 10 Meter[1]. [27], Duvillaea bull kelp diversity appears to have been affected by uplift along the Akatore fault zone. November 2019 um 18:53 Uhr bearbeitet. Die Art ist dadurch wahrscheinlich auf der Südhalbkugel stärker verbreitet als die anderen Arten ihrer Gattung, deren Phylloiden keine Luftkammern enthalten[3]. [22], Earthquake uplift that raises the intertidal zone by as little as 1.5 metres can cause Durvillaea bull kelp to die off in large numbers. [11], The 2010 Chile earthquake caused significant coastal uplift (~0.2 to 3.1 m), particularly around the Gulf of Arauco, Santa María Island and the Bay of Concepción. GET A FREE QUOTE.

Durvillaea antarctica antioxidant algae extract was obtained by an aqueous extraction process.. D. antarctica extract was successfully encapsulated into electrospun PVA fibers (PVA-C).. D. antarctica nanoparticles act as reinforcement phase and active agent for plasticized-PLA films.. PVA-C improved the thermal stability, the mechanical and barrier performance of plasticized-PLA. [11][15][23][24][25] The loss of Durvillaea kelp caused ecological disturbance, significantly affecting the biodiversity of the local intertidal community. Durvillaea antarctica is a brown seaweed that can be located in the Southern Hemisphere and has a high content of polyunsaturated fatty acids and γ-tocopherol. Die Alge wird in Chile als Grundnahrungsmittel genutzt und ist hier als Cochayuyo bekannt[1]. Papers overview. [38], Māori use D. antarctica (rimurapa) and D. poha to make traditional pōhā bags, which are used to transport food and fresh water, to propagate live shellfish, and to make clothing and equipment for sports.

Such traditional uses include the use of cochayuyo ( Durvillaea antarctica) in Chile ( Cardenas Alvarez & Munoz Arias, 2008 ), or the production of flour from ‘llaska’ (i.e. D. antarctica, an alga, does not have air bladders, but floats due to a unique honeycomb structure within the alga' Intertidal species of Durvillaea can be used to estimate earthquake uplift height, with comparable results to traditional methods such as lidar. Durvillaea antarctica (Chamisso) Hariot, 1892 bull kelp Native range | All suitable habitat | Point map | Year 2100: This map was computer-generated and has not yet been reviewed. The coastline at this point is very exposed to wave action and one of the dominant features … Laing) W.A. [3][5] Notably, additional unclassified lineages were estimated within D. [38] Exclusive harvest rights are designated using coves or caletas, and the income for fishers (and their unions) often depends upon the sale of cochayuyo. Durvillaea antarctica National Institutes of Health Create Alert. Durvillaea antarctica is a large, robust bull kelp species and the dominant seaweed in southern New Zealand and Chile. Much of the available data are for the species Durvillaea antarctica, D. willana, and D. potatorum. in a way that maintains its nutritional properties, such as iodine, minerals, fiber, proteins, and also has all the essential amino acids. Bei der Durvillea antarctica handelt es sich um eine widerstandsfähige Großalge mit einem kräftigen Cauloid (Stiel)[2]. South. [3][5], D. potatorum was used extensively for clothing and tools by Aboriginal Tasmanians, with uses including material for shoes and bags to transport freshwater and food. Gel electrophoresis showed that the acidic polysaccharide (23.5% sulfate, 4.5% uronic acid) was not homogeneous. Durvillaea antarctica Taxonomy ID: 112057 (for references in articles please use NCBI:txid112057) current name. [39][40] The Ngai Tahu Claims Settlement Act 1998 protects Durvillaea bull kelp from commercial harvesting within the tribe's traditional seaweed-gathering areas.[42]. [3][37] The same species is also called cochayuyo (cocha: lake, and yuyo: weed), and hulte in Quechua. Phylogeographic analyses using mitochondrial COX1 sequence data and genotyping by sequencing data for thousands of anonymous nuclear loci, indicate that a historic uplift event (800 – 1400 years before present) along the fault zone and subsequent recolonisation, has left a lasting impact upon the genetic diversity of the intertidal species D. antarctica and D. poha, but not on the subtidal species D. Taken together, these findings suggest that these algae extracts may be potential … Durvillaea antarctica From Wikipedia, the free encyclopedia Durvillaea poha (recently split as a new species from D. antarctica ) stipes on Second Bay, Otago, New Zealand Die Gattung wurde zu Ehren von Jules Dumont d’Urville benannt.

Supply Ability: 150 Ton/Tons per Month : Weight (kg): 1 - 2 Kg : Processing Type: CHOPPED : Place of Origin: Chile : Use: Food : … Experimental analyses of diversity partitioning in southern hemisphere algal communities. Ten mathematical models were applied on the drying kinetics. [10][28] Such a genetic impact may support the founder takes all hypothesis. Durvillaea antarctica. [17] In New Zealand, Durvillaea fronds can also be infected by the obligate red algal epiphyte Pyrophyllon subtumens (J. Agardh ex R.M. Durvillea antarctica, auch Cochayuyo oder Bull Kelp genannt, ist eine große Seetangart der Braunalgen aus dem subantarktischen Küstenbereich. [6], Durvillaea species are characterised by their prolific growth and plastic morphology. [3][9] In contrast, species as D. willana lack such 'honeycomb' tissue and are non-buoyant, preventing the plants from moving long distances. The drying characteristics of edible seaweed Durvillaea antarctica subjected to hot‐air drying at 40, 50, 60, 70, and 80°C were investigated. The genus is named after French explorer Jules Dumont d'Urville (1790-1842). [36], D. antarctica and D. incurvata have been used in Chilean cuisine for salads and stews, predominantly by the Mapuche indigenous people who refer to it as collofe or kollof. However, the relationship between benthic populations and stranded seaweeds has received little attention. Exporter. Durvillaea antarctica, allgemein bekannt als Cochayuyo, ist eine große, robuste Stier Seetang - Arten und die dominanten Algen im südlichen Neuseeland und Chile. [25], It has been hypothesised that gaps in the current geographic range of D. willana around Wellington and the Wairarapa may have been caused by local extinction following historic earthquake uplift events such as the 1855 Wairarapa earthquake. the nutritional value of the Ulva lactuca and Durvillaea antarctica species which represent natural resources with potential economic value for use in human and animal nutrition. [12][13][14], Specimens of Durvillaea can detach from substrates, particularly during storms. Semantic Scholar uses AI to extract papers important to this topic. [34][35] Currently, D. potatorum is collected as beach wrack from King Island, where it is then dried as chips and sent to Scotland for phycocolloid extraction. New Zealand Bull Kelp Durvillaea antarctica. Zur Navigation springen Zur Suche springen. Certifications. Kelp-associated invertebrates can be transported inside of drifting kelp holdfasts, potentially leading to long-distance dispersal and a significant impact upon the population genetic structure of the invertebrate species. 2. In this work Ni(II) and Cr(III) adsorption on Durvillaea antarctica surface were studied, optimal condition of pH, adsorption time is achieved at pH 5.0, with contact times of 240 and 420 minutes for a maximum adsorption capacity of 32.85 and 102.72 mg g–1 for Ni(II) and Cr(III), respectively.
