[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. [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. 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. [25], Intertidal species of Durvillaea can be used to estimate earthquake uplift height, with comparable results to traditional methods such as lidar. Sie erreicht eine Länge von bis zu 10 Meter[1]. David R. Schiel; Oecologia; 2019; Corpus ID: 108292578 . 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-to… Long-term persistence of the floating bull kelp Durvillaea antarctica from the South-East Pacific: Potential contribution to local and transoceanic connectivity. [17] In New Zealand, Durvillaea fronds can also be infected by the obligate red algal epiphyte Pyrophyllon subtumens (J. Agardh ex R.M. [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. 6 Use of Durvillaea species; 7 References; 8 Further reading; 9 External links; Common name and etymology. (e.g., as food) are described, along with recommendations for harvest timing and methods. 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. Cladophora crispata) by a local population of Titicaca lake border in Peru ( Canales, Taquila, Pacheco, Salas, & Aguilar, 2008 ). D. antarctica has a circumpolar distribution between the latitudes of 29°S (in Chile) and 55°S (on Macquarie Island). [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. [9], Durvillaea bull kelp grow within intertidal and shallow subtidal areas, typically on rocky wave-exposed coastal sites. Sie erreicht eine Länge von bis zu 10 Meter[1]. The coastline at this point is very exposed to wave action and one of the dominant features … "A morphological and phylogenetic investigation into divergence among sympatric Australian southern bull kelps (, "The biogeographic importance of buoyancy in macroalgae: a case study of the southern bull‐kelp genus, "The genomic footprint of coastal earthquake uplift", "Using a calibrated upper living position of marine biota to calculate coseismic uplift: a case study of the 2016 Kaikōura earthquake, New Zealand", "Circumpolar dispersal by rafting in two subantarctic kelp-dwelling crustaceans", "Passive rafting is a powerful driver of transoceanic gene flow", "An integrated ecological, genetic and geological assessment of long-distance dispersal by invertebrates on kelp rafts", "Communities and Attachment Networks Associated with Primary, Secondary and Alternative Foundation Species; A Case Study of Stressed and Disturbed Stands of Southern Bull Kelp", "Kelp forests after the Kaikōura Earthquake", "SNP analyses reveal a diverse pool of potential colonists to earthquake-uplifted coastlines", "Effects of rocky shore coseismic uplift and the 2010 Chilean mega-earthquake on intertidal biomarker species", "Kelp water carrying sculptures mad by Nannette Shaw win Victorian Aboriginal art award", "Proposal for the harvest and export of native flora under the Environment Protection and Biodiversity Conservation Act 1999", "Maori shellfish project wins scholarship",, Articles containing Mapudungun-language text, Articles containing Quechua-language text, Creative Commons Attribution-ShareAlike License, This page was last edited on 26 November 2020, at 06:10. Das Phylloid (das blattähnliche Organ der Alge) ist schmal und band-förmig. [26] This uplift caused large scale die offs of D. antarctica and dramatically affected the intertidal community. Nelson 2003.[18][19]. November 2019 um 18:53 Uhr bearbeitet. [3][9] In contrast, species as D. willana lack such 'honeycomb' tissue and are non-buoyant, preventing the plants from moving long distances. Much of the available data are for the species Durvillaea antarctica, D. willana, and D. potatorum. 2019. Certifications. Nach der Befruchtung wird sofort wieder eine diploide Alge gebildet. Ten mathematical models were applied on the drying kinetics. 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 [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. F. Tala, B. López, +5 authors M. Thiel; Marine environmental research ; 2019; Corpus ID: 173993590. [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. [6], Durvillaea species are characterised by their prolific growth and plastic morphology. [11][15][23][24][25] The loss of Durvillaea kelp caused ecological disturbance, significantly affecting the biodiversity of the local intertidal community. Diese Seite wurde zuletzt am 1. All members of the genus are found in the southern hemisphere, including Australia, New Zealand, South America, and various subantarctic islands. New!! Die Gattung wurde zu Ehren von Jules Dumont d’Urville benannt. See more » Edible seaweed. [1] All species are restricted to the Southern Hemisphere and many taxa are endemic to particular coastlines or subantarctic islands. Domain: Eukaryota • Regnum: Chromista • Phylum: Ochrophyta • Classis: Phaeophyceae • Ordo: Fucales • Familia: Durvillaeaceae • Genus: Durvillaea • Species: Durvillaea antarctica (Chamisso) Hariot 1892 Synonyme. Get Latest Price Quick Details Port: Coquimbo : Payment Terms: L/C,D/P,T/T,The conditions that the buyer decides and agrees with Abimar. Materials and methods 2.1. Experimental analyses of diversity partitioning in southern hemisphere algal communities. antarctica. [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. Gel electrophoresis showed that the acidic polysaccharide (23.5% sulfate, 4.5% uronic acid) was not homogeneous. Es werden durch eine Meiose unbewegliche Eizellen und bewegliche Spermatozoiden gebildet . Im Phylloid befinden sich Luftkammern, die Honigwaben ähneln[3]. [3][8] When these species detach from the seabed, this buoyancy allows for plants to drift for substantial distances, permitting long distance dispersal. Die Gattung wurde zu Ehren von Jules Dumont d’Urville benannt. Bei der Durvillea antarctica handelt es sich um eine widerstandsfähige Großalge mit einem kräftigen Cauloid (Stiel)[2]. Sorry! 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. 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. GET A FREE QUOTE. 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. Wenn die Alge vom Substrat losgerissen wird, fördern die Luftkammern durch Auftrieb auch den Transport der Alge. Christiaan van den Hoek, David Mann und M. Jahns:, Lebewesen in menschlicher Nutzung und Haltung, „Creative Commons Attribution/Share Alike“. [12][13][14], Fronds of D. antarctica can be infected by an endophytic, phaeophycean algal parasite Herpodiscus durvillaeae (Lindauer) G.R. Das Wachstum erfolgt diffus und nicht, wie bei anderen Vertreter der Ordnung Fucales, durch eine Scheitelzelle[3].
