In Alaskan kelp forest ecosystems, sea otters are the keystone species that mediates this trophic cascade. In Southern California, kelp forests persist without sea otters and the control of herbivorous urchins is instead mediated by a suite of predators including lobsters and large fishes, such as the California sheephead.
This "kelp highway hypothesis" suggested that highly productive kelp forests supported rich and diverse marine food webs in nearshore waters, including many types of fish, shellfish, birds, marine mammals, and seaweeds that were similar from Japan to California, Erlandson and his colleagues also argued that coastal kelp forests reduced wave ...
Kelp forests provide important habitats for many fish species, sea otters and sea urchins. Directly and indirectly, marine coastal ecosystems provide vast arrays of ecosystem services for humans, such as cycling nutrients and elements , and purifying water by filtering pollutants.
Kelp forests occur worldwide throughout temperate and polar coastal oceans. [10] In 2007, kelp forests were also discovered in tropical waters near Ecuador. [11] Physically formed by brown macroalgae, kelp forests provide a unique habitat for marine organisms [12] and are a source for
Nereocystis, like other large, canopy forming kelps, play a crucial role in maintaining the biologically diverse kelp forests in the temperate marine environments where they flourish. [14] Its fast growth and size provide an important habitat not only for the fish and invertebrates that reside in kelp forests, but also for species that use kelp ...
Macrocystis is a monospecific genus [3] of kelp (large brown algae) with all species now synonymous with Macrocystis pyrifera. It is commonly known as giant kelp or bladder kelp. This genus contains the largest of all the Phaeophyceae or brown algae. Macrocystis has pneumatocysts at the base of its blades.
Kelp forests are some of the most diverse and productive ecosystems and in the UK cover an area similar in size to the country’s woodlands. Skip to main content. 24/7 Help. For premium support ...
A kelp forest in San Clemente Island, California demonstrating the diversity of life that can be supported by Marine Permaculutre. Marine Permaculture is a form of mariculture that reflects the principles of permaculture by recreating seaweed forest habitat and other ecosystems in nearshore and offshore ocean environments.
