Kina populations throughout New Zealand have dramatically grown due to the effects of overfishing and climate change, resulting in over-grazing that significantly damages kelp forest ecosystems. Kina are now being actively removed from many ecosystems for marine conservation efforts.
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. They sequester carbon as a cushion against climate change.
A potential threat that may arise is loss of habitat due to climate change and its resulting consequences such as ocean acidification and pollution, as well as destruction and/or massive die-offs of kelp forests. This poses a threat because this species depends on dense canopies of kelp for protection from predators and for reproduction.
Sep. 22—Maine is one of the first states to consider the carbon storage potential of seaweed in its carbon budget, a biennial accounting of the balance between locally produced greenhouse gas ...
Just one example is the giant bull kelp Nereocystis luetkeana, which have evolved to change blade shape in order to increase drag in water and interception of light when exposed to certain environments. Bull kelp are not unique in this adaptation; many kelp species have evolved a genetic plasticity for blade shapes for different water flow ...
Researchers are also helping the animals build starter dams, also known as beaver dam analogs, to ensure the process works. "It's amazing all the steps that we have to do to help out something ...
Watch the video below to see the unlikely friendship develop at the animal sanctuary! According to the sanctuary, Marble offered William "the gentle nurturing" he was craving.
Seaweed farming is a carbon negative crop, with a high potential for climate change mitigation. [27] [28] The IPCC Special Report on the Ocean and Cryosphere in a Changing Climate recommends "further research attention" as a mitigation tactic. [29] World Wildlife Fund, Oceans 2050, and The Nature Conservancy publicly support expanded seaweed ...
