Plant washed ashore, Hainan Island, Xianhai, April 2012. 4. It has no English common name, but the Japanese call it akamoku. Sargassum contains higher amounts of protein essential The biomass of this alga as a vital component in coastal water ecology has been well documented. Recently, an extreme amount of S. horneri moved into the coasts of Jeju Island from the east coast of China, which … Thalli of three Japanese Sargassum species, S.fusiforme, S.horneri and the native S.muticum, hereafter S.muticum (nat. ), were collected by Scuba diving in Oshima, Japan (33°55′04.4"N 132°27′42.7"E—33°56′26.3"N 132°24′06.0"E) during January and March 2013 at a depth of 1–3 m. The invasive population of S.muticum, hereafter S. Sargassum horneri (Turner) C. Agardh is one of the main components of the seaweed bed in the temperate coasts of Eastern Asia. 2007), now considered a synonym of S. horneri (Uwai et al. When Sargassum loses its buoyancy, it sinks to the seafloor, providing energy in the form of carbon to fishes and invertebrates in the deep sea, thus serving as a potentially important addition to deep-sea food web. This annual species reaches 2–5 m or more in height and sometimes dominates on the rocky shores of intertidal to subtidal zones, especially from winter to early summer. Sargassum horneri (Sargassaceae, Fucales, Phaeophyta) is an edible brown seaweed, abundant worldwide in shal-low sea-water ecosystems (Herath et al. The distinct genesis and blooming dynamics of the two seaweed species were detected and described. In Japanese waters, where it originates, it is a relatively small, innocuous seaweed (1-2 m in length). Sargassum horneri is native from Asia, and distributed in Japan, Korea, Hong Kong(China), Chinese Taipei and China Mainland [18]. We developed a clonal culture of Sargassum horneri to investigate the effect of photoperiod on reproduction in this species. In particular, S. horneri formed dense assemblages at 4 7 m water depth. 5. Development of oogonia of Sargassum horneri (Fucales, Heterokontophyta) and concomitant variations in PSII photosynthetic activities XIUJUN XIE 1,GUANGCE WANG 2*, GUANGHUA PAN 1,JIANZHANG SUN 3 AND JIAN LI 4 1Tianjin Key Laboratory of Marine Resources and Chemistry, College of Marine Science and Engineering, Tianjin University of Science and Technology, Tianjin 300457, China It was observed in Catalina Island, California, in 2003 [19]. Currently, little is known about the biology and ecology of this invasive alga in its introduced range. To study the life history processes and morphological traits of Sargassum horneri from the Sargassum seaweed bed of Gouqi Island, this study first conducted the investigation of the growth and reproduction during an annual cycle of Sargassum horneri, and 16 related biological parameters including individual length, blade, vesicle and receptacle were analyzed. 2009). 3. Regenerated vegetative thalli were obtained using lateral branches excised from a thallus grown from a single embryo under short‐day conditions (SD = … PY - 2018/12/13. horneri (Turner) C. Agardh can propagate through both germlings and vegetative reproduction and branches separated from a shoot will continue to grow into a new fronds (Uchida 1993). sargassum beds provide food, habitat, and nursery grounds for a wide array of marine organisms (Tsukidate 1992), while also providing food, alginates, feed, and bioactive compounds for people who harvest or culture sargassum (Belleme and Belleme 2007, Zhao et al. During reproduction, dislodged seaweeds of the genus Sargassum form large pelagic surface rafts that can persist for several weeks, and potentially act as a dispersal vector. An unprecedented bi-macroalgal bloom caused by Ulva prolifera and Sargassum horneri occurred from spring to summer of 2017 in the western Yellow Sea (YS) of China, where annual large-scale green tides have prevailed for a decade. Sargassum horneri is an edible brown alga that grows in the subtidal zone as an annual species along the coasts of South Korea, China, and Japan. Y1 - … It was first disco-vered in the eastern Pacific in Long Beach Harbor in 2003 and identified as S. filicinum Harvey, 1860 (Miller et al. Cultivation of the brown alga Sargassum horneri: sexual reproduction and seedling production in tank culture under reduced solar irradiance in ambient temperature Author: Pang, Shao Jun; Liu, Feng; Shan, Ti Feng; Gao, Su Qin; Zhang, Zhi Huai Methods: In this study, potential of S. horneri was evaluated through anti-MMP effect in HT1080 fibrosarcoma cells. 2013)(1). Preparation of Microporous Carbon from Sargassum horneri by Hydrothermal Carbonization and KOH Activation for CO2 Capture. The present study was designed to evaluate the anti-inflammatory properties of S. horneri using an in vivo mouse asthma model following exposure to particulate matter (PM). Internal differentiation of tissues of the plant body with division of labour. Author(s): Marks, Lindsay | Advisor(s): Holbrook, Sally J | Abstract: Sargassum horneri is a seaweed native to eastern Asia that has recently become established in the coastal waters of southern California and Baja California, Mexico. In surface rafts, seaweeds are rapidly exposed to increased light, elevated … In contrast, the Munseom site, located on Jeju Island, is very exposed to … As a large conspicuous intertidal brown alga, individuals of Sargassum horneri can reach a length of more than 7 m with a fresh weight of 3 kg along the coasts of the Eastern China Sea. Sargassum, also called gulfweed or sea holly, genus of about 150 species of brown algae (family Sargassaceae) generally attached to rocks along coasts in temperate regions or occurring as pelagic (free-floating) algae in the open sea. Sargassum horneri is one of the most important habitat-forming species in the NW-Pacific, where it annually forms large-scale floating mats (Li et al., 2020). The most recent arrival in our waters, Sargassum horneri, was first collected from Long Beach Harbor in 2003.This alga is a native of Korea, Japan, and China as far south as Hong Kong. Special features of Genus Sargassum: 1. Marine algae S. horneri [Sargassum horneri (Turner) C. Agardh] was seasonally gathered from the coast at Shimoda (Shizuoka Prefecture, Japan) and Miyako (Iwate Prefecture, Japan), and it was freeze-dried and powered [16]. Absence of any kind of spores.
