Eisenia Arborea
''Eisenia arborea'', or the southern sea palm (not to be confused with the sea palm), is a dominant species of kelp that is found on the western Pacific coast of North America, from Vancouver Island, Canada south to Mexico's Isla Magdalena and Baja California, as well as in Japan. They are commonly found from the midtidal areas stretching to the subtidal areas. It is an edible seaweed, a source of nutrients for grazing marine invertebrates and a source of alginic acid, a food thickener. Some of the algas have a hollow stipe above its holdfast with two branches terminating in multiple blades. Eisenia arborea is studied in order to predict environmental stress in oceans intertidal zones. Hollow stipes where present when the Eisenia arborea did not receive essential nutrients for its thalli development. Eisenia arborea with hollow stripes are believed to be evolved algae in order to increase their survival in harsh living conditions. They play a huge role in determining envir ...

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. The Rhodophyta also comprises one of the largest phyla of algae, containing over 7,000 currently recognized species with taxonomic revisions ongoing. The major ...

Sea Palm
''Postelsia palmaeformis'', also known as the sea palm (not to be confused with the southern sea palm) or palm seaweed, is a species of kelp and classified within brown algae. It is the only known species in the genus Postelsia. The sea palm is found along the western coast of North America, on rocky shores with constant waves. It is one of the few algae that can survive and remain erect out of the water; in fact, it spends most of its life cycle exposed to the air. It is an annual, and edible, though harvesting of the alga is discouraged due to the species' sensitivity to overharvesting. History The sea palm was known by the natives of California by the name of kakgunu-chale before any Europeans entered the region. ''Postelsia'' was first scientifically described by Franz Josef Ruprecht (1814–1870) in 1852 from a specimen found near Bodega Bay in California. Ruprecht, an Austro-Hungary, Austro-Hungarian who became curator of botany at the Academy of Sciences in St. Petersb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Coast
Pacific coast may be used to reference any coastline that borders the Pacific Ocean. Geography Americas Countries on the western side of the Americas have a Pacific coast as their western or southwestern border, except for Panama, where the Pacific coast is primarily on its southern border. The first Europeans to see the Pacific Ocean were able to do so by crossing the narrow Panama isthmus. The unique position of Panama in relation to the Pacific Ocean resulted in the ocean initially being named the South Sea. * West Coast of Canada * Geography of Chile * Geography of Colombia * Geography of Costa Rica * Geography of Ecuador * Geography of El Salvador * Geography of Guatemala * Geography of Honduras * Pacific Coast of Mexico * Geography of Nicaragua * Geography of Panama * Geography of Peru * West Coast of the United States Asia Countries on the eastern and southeastern sides of Asia have a Pacific coast as part (or all) of their border. * * Geography of Japan * Geography of ...

Vancouver Island
Vancouver Island is an island in the northeastern Pacific Ocean and part of the Canadian Provinces and territories of Canada, province of British Columbia. The island is in length, in width at its widest point, and in total area, while are of land. The island is the largest by area and the most populous along the west coasts of the Americas. The southern part of Vancouver Island and some of the nearby Gulf Islands are the only parts of British Columbia or Western Canada to lie south of the 49th parallel north, 49th parallel. This area has one of the warmest climates in Canada, and since the mid-1990s has been mild enough in a few areas to grow Mediterranean Sea, Mediterranean crops such as olives and lemons. The population of Vancouver Island was 864,864 as of 2021. Nearly half of that population (~400,000) live in the metropolitan area of Greater Victoria, the capital city of British Columbia. Other notable cities and towns on Vancouver Island include Nanaimo, Port Alberni, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Magdalena Island (Mexico)
Magdalena Bay ( es, Bahía Magdalena) is a long bay in Comondú Municipality along the western coast of the Mexican state of Baja California Sur. It is protected from the Pacific Ocean by the unpopulated sandy barrier islands of Isla Magdalena and Isla Santa Margarita. Ecology This bay is particularly noted for the seasonal migration of the California gray whales that come here during winter to calve. The bay is also popular for commercial and sports fishing. Nearby mangrove swamps provide sanctuaries for sea birds. The bay includes the small fishing port of San Carlos, as well as Puerto López Mateos, which provides a good place to observe the whales. Islands Sandy barrier islands Isla Magdalena and Isla Santa Margarita separate the bay from the Pacific Ocean. Magdalena, mostly to the north and facing northwest, is a long, slender, segmented island that parallels the coast a few miles north. There is a small settlement, Puerto Magdalena mostly active during whale wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Edible Seaweed
Edible seaweed, or sea vegetables, are seaweeds that can be eaten and used for culinary purposes. They typically contain high amounts of fiber. They may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae. Seaweeds are also harvested or cultivated for the extraction of polysaccharides such as alginate, agar and carrageenan, gelatinous substances collectively known as hydrocolloids or phycocolloids. Hydrocolloids have attained commercial significance, especially in food production as food additives. The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids. Most edible seaweeds are marine algae whereas most freshwater algae are toxic. Some marine algae contain acids that irritate the digestion canal, while others can have a laxative and electrolyte-balancing effect. Most marine macroalgae are nontoxic in normal quantities, but members of the genus ''Lyngbya'' ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Invertebrate
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Alginic Acid
Alginic acid, also called algin, is a naturally occurring, edible polysaccharide found in brown algae. It is hydrophilic and forms a viscous gum when hydrated. With metals such as sodium and calcium, its salts are known as alginates. Its colour ranges from white to yellowish-brown. It is sold in filamentous, granular, or powdered forms. It is a significant component of the biofilms produced by the bacterium ''Pseudomonas aeruginosa'', a major pathogen found in the lungs of some people who have cystic fibrosis. The biofilm and ''P. aeruginosa'' have a high resistance to antibiotics, but susceptible to inhibition by macrophages. Structure Alginic acid is a linear copolymer with homopolymeric blocks of (1→4)-linked β-D- mannuronate (M) and α-L- guluronate (G) residues, respectively, covalently linked together in different sequences or blocks. The monomers may appear in homopolymeric blocks of consecutive G-residues (G-blocks), consecutive M-residues (M-blocks) or alterna ...
