Despite its appearance, kelp is not a plant but a stramenopile (a group containing many protists). [4] Kelp grows in "underwater forests" (kelp forests) in shallow oceans. Kelps were previously thought to have appeared in the Miocene, 5 to 23 million years ago based on fossils from California. [5]
To establish itself, a young kelp produces one or two primary blades, and begins a rudimentary holdfast, which serves to anchor the plant to the rocky bottom. As the kelp grows, additional blades develop from the growing tip, while the holdfast enlarges and may entirely cover the rock to which it is attached. [citation needed]
An alternative offset would be to cultivate kelp forests. Kelp can grow at 2 feet per day, 30 times faster than terrestrial plants. Planting kelp across 10% of the oceans (4.5 x the area of Australia) could provide the same offset. Additionally, the kelp would support a fish harvest of 2 megatons per year and reduce ocean acidification. Large ...
Smaller areas of anchored kelp are called kelp beds. They are recognized as one of the most productive and dynamic ecosystems on Earth. [ 1 ] [ 2 ] Although algal kelp forest combined with coral reefs only cover 0.1% of Earth's total surface, they account for 0.9% of global primary productivity . [ 3 ]
Nereocystis (Greek, 'mermaid's bladder') is a monotypic genus of subtidal kelp containing the species Nereocystis luetkeana. [1] Some English names include edible kelp, bull kelp, bullwhip kelp, ribbon kelp, bladder wrack, and variations of these names. [2]
Pleurophycus gardneri is a habitat to many species of amphipod, and most commonly supports species specific to stipe burrowing. [2] Amphipods decrease the lifespan of this kelp due to damages caused by burrowing; any breaks in the plants' holdfast up to its stipe will kill the plant, hence its heightened mortality rate due to stipe burrowing amphipods.
Although archaeological evidence of seaweed is hard to find because of its easy decomposition, some plant remains of wakame seaweed are found in some ruins of the Jōmon Period [12] which leads to the supposition that kombu was also eaten at that time. As to surviving documents, the letters 軍布 (in Sino-Japanese reading 軍 is gun/kun; 布 ...
Wakame (Undaria pinnatifida) is a species of kelp native to cold, temperate coasts of the northwest Pacific Ocean. As an edible seaweed, it has a subtly sweet, but distinctive and strong flavour and satiny texture.
