So individuals of the same species will have differences to other individuals of the same species due to what habitat they grow in. [19] Many species have different morphologies for different wave disturbance regimes [18] but giant kelp Macrocystis integrifolia has been found to have plasticity allowing for 4 distinct types of blade morphology ...
In ideal conditions, giant kelp (Macrocystis spp.) can grow as much as 30–60 cm vertically per day. Some species, such as Nereocystis , are annuals , while others such as Eisenia are perennials , living for more than 20 years. [ 19 ]
[23] [24]: 8 They can grow at a rate of 60 cm (2 ft) a day to reach over 45 m (150 ft) long in one growing season. [8] [25] [26] Juvenile giant kelp grow directly upon their parent female gametophyte. 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 ...
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 ...
It can reach 60 m (200 ft) in length and grow as rapidly as 50 cm (20 in) a day. [51] According to one study, covering 9% of the world's oceans with kelp forests could produce "sufficient biomethane to replace all of today's needs in fossil fuel energy, while removing 53 billion tons of CO 2 per year from the atmosphere, restoring pre ...
