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… [17] In New Zealand, Durvillaea fronds can also be infected by the obligate red algal epiphyte Pyrophyllon subtumens (J. Agardh ex R.M. 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. New Zealand Bull Kelp Durvillaea antarctica. Long-term persistence of the floating bull kelp Durvillaea antarctica from the South-East Pacific: Potential contribution to local and transoceanic connectivity. Taken together, these findings suggest that these algae extracts may be potential … [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. 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 Zur Navigation springen Zur Suche springen. Available for marketplace users Contact. Der Artname D. antarctica ist irreführend, da sie nicht in der antarktischen Region vorkommt. 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. Der Artname D. antarctica ist irreführend, da sie nicht in der antarktischen Region vorkommt. 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. Es werden durch eine Meiose unbewegliche Eizellen und bewegliche Spermatozoiden gebildet (Oogamie). [16][17] Based on genetic evidence, H. durvillaeae also seems to have also been be transmitted via rafting. [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. Die Gattung wurde zu Ehren von Jules Dumont d’Urville benannt. Durvillaea Antarctica Agriculture and Live Animals. [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][9] In contrast, species as D. willana lack such 'honeycomb' tissue and are non-buoyant, preventing the plants from moving long distances. 2. Sorry! There are currently eight recognised species within the genus, and the type species is D. The genus is named after French explorer Jules Dumont d'Urville (1790-1842).

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. Free and Open Access to Biodiversity Data. [4], Die Verbreitung reicht nördlich von 29° S in Chile über die subantarktischen Inseln bis Neuseeland.[5]. 2019. Das Wachstum erfolgt diffus und nicht, wie bei anderen Vertreter der Ordnung Fucales, durch eine Scheitelzelle[3]. Durvillaea is a genus of brown algae in the monotypic family Durvillaeaceae. willana. 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. Edible seaweed, or sea vegetables, are algae that can be eaten and used in the preparation of food. Ten mathematical models were applied on the drying kinetics. 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.

[6], Durvillaea species are characterised by their prolific growth and plastic morphology. 2019. [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. [9], Durvillaea bull kelp grow within intertidal and shallow subtidal areas, typically on rocky wave-exposed coastal sites. However, the relationship between benthic populations and stranded seaweeds has received little attention. GET A FREE QUOTE. 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. Bei der Durvillea antarctica handelt es sich um eine widerstandsfähige Großalge mit einem kräftigen Cauloid (Stiel)[2]. The coastline at this point is very exposed to wave action and one of the dominant features … [22] Once the kelp was extirpated, the invasive kelp Undaria pinnatifida recruited in high densities. [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. See more » Edible seaweed.
