[1] Macrocystis pyrifera, commonly known as giant kelp or giant bladder kelp, is a species of kelp (large brown algae), and one of four species in the genus Macrocystis. Giant kelp, Macrocystis pyrifera, increases faunal diversity through physical engineering. Macrocystis pyrifera (Linnaeus) C.Agardh, 1820, World Register of Marine Species (WoRMS) (englisch), Sie können nur Bilder im JPEG-Format hochladen, Sie müssen die Urheberrechte an dem Foto besitzen. Instead, it is a brown alga and is part of the large kingdom of life known as the Protista. Commonly known as giant kelps, Macrocystis species can form massive kelp forests and provide important habitats for numerous fish and marine invertebrates. Algae species are divided into different groups based on their characteristics. [2] In den Riesentang-Wäldern vor der Küste Kaliforniens sind die Sporophyten langlebig und bilden unter der Wasseroberfläche ausgedehnte, den Untergrund beschattende "Kronendächer" aus. The photobiological traits (e.g. [3], Er wächst in Küstennähe unterhalb der Niedrigwasserlinie, meist in 6–20 Meter Wassertiefe, in sehr klarem Wasser selten bis 80 Meter Wassertiefe.

The giant kelp, Macrocystis pyrifera, is the largest marine alga in the world and supports one of the most productive ecosystems on earth.While the processes governing its growth have been well studied, the processes that drive the loss of foliar biomass are poorly understood. 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. Table 29.1 gives some sequential parameters (determined by high field NMR spectroscopy) for samples of these alginates. [2] Auch als Futter für Seeschnecken-(Abalone)-Kulturen wird der Riesentang genutzt.[3]. Macrocystis pyrifera, with many common names including Giant kelp, kelp, giant bladder kelp, Pacific kelp and brown kelp is actually a species of kelp (large brown algae), and one of four species in the genus Macrocystis.
