macrocystis pyrifera การใช้

• On 21 April the giant kelp " Macrocystis pyrifera " was found off Campbell's Island for the spring months.
• One species, " Macrocystis pyrifera ", under this genus, has the fastest linear growth of any organism on earth.
• Recent genetic research increasingly favors the grouping of all " Macrocystis " species into one : " Macrocystis pyrifera ."
• It is a herbivore and constructs a tubular nest-like home on a blade of the sporophyte of the giant kelp " Macrocystis pyrifera ".
• Kashtayit SMCA prohibits take of living marine resources except : recreational take of finfish, invertebrates except rock scallops and mussels, and giant kelp ( Macrocystis pyrifera ) by hand harvest is allowed.
• In contrast, the giant kelp " Macrocystis pyrifera " bears many blades along its stipe, with a pneumatocyst at the base of each blade where it attaches to the main stipe.
• Commercial varieties of alginate are extracted from seaweed, including the giant kelp " Macrocystis pyrifera ", " Ascophyllum nodosum ", and various types of " Laminaria ".
• Whereas sticklebacks use this secretion to bind plant matter together to create a nest, the tube-snout simply attaches its eggs to a substrate . " Aulorhynchus " attaches its eggs to kelp, notably " Macrocystis pyrifera ".
• The stipe may be relatively flexible and elastic in species like " Macrocystis pyrifera " that grow in strong currents, or may be more rigid in species like " Postelsia palmaeformis " that are exposed to the atmosphere at low tide.
• Brown seaweeds are usually large, and range from the giant kelp " Macrocystis pyrifera " that is often 20 m long, to thick, leather-like seaweeds from 2-4 m long, to smaller species 30 60 cm long.
• Giant kelp, " Macrocystis pyrifera ", has been utilized for many years as a food source; it contains many compounds such as iodine, potassium, other minerals vitamins and carbohydrates and thus has also been used as a dietary supplement.
• The forests of " Macrocystis pyrifera " form a protective canopy, fostering the ideal temperature for various species that are temperature sensitive, such as " C . sitchensis ", and the growth of macroalgae and coralline algae needed for their survival.
• For example, in California, " Macrocystis pyrifera " forests, the nudibranch " Melibe leonina ", and skeleton shrimp " Caprella californica " are closely associated with surface canopies; the kelp perch " Brachyistius frenatus ", rockfish " Sebastes " spp ., and many other fishes are found within the stipitate understory; brittle stars and turban snails " Tegula " spp . are closely associated with the kelp holdfast, while various herbivores, such as sea urchins and abalone, live under the prostrate canopy; many seastars, hydroids, and benthic fishes live among the benthic assemblages; solitary corals, various gastropods, and echinoderms live over the encrusting coralline algae.
