and range from San mateo County in the north to Santa barbara County in the South sea otters live offshore in forests of kelp--huge yellow-brown rubbery seaweed reaching from the sea floor to the surface like tall trees.
In coastal North america sea otters help maintain healthy kelp forests which benefits other marine species dependent on this habitat.
which in unchecked hordes will chew through the holdfasts of the kelp leaving vast barrens in place of the vibrant forests.
whose presence has outsized an effect on its kelp forest habitat. Without sea otters the undersea sea urchins they prey on would devour the kelp forests resulting in dense areas called sea urchin barrens that have lower biodiversity due to the loss of kelp that provide 3-dimensional habitat
and a food source for many species. Researchers found that when sea otters arrive in an area from
As a result the kelp forest begins to grow back changing the structure of kelp forest communities.
Many fish marine mammals and birds are also found in kelp forest communities including rockfish seals sea lions whales gulls terns snowy egrets as well as some shore birds.
because healthy kelp forests can grow rapidly and store large amounts of carbon. Dr. Martone's analyses of the effects of sea otters on kelp forest ecosystems can help shape predictions of how climate change
and trophic cascades in concert with other drivers affect coastal ecosystems. The ecological impacts of a changing climate are evident from terrestrial polar regions to tropical marine environments.

or human being says lead author Jianwu (Jim) Tang an assistant scientist in the MBL Ecosystem Center.
But Tang and colleagues found both energy production (photosynthesis) and energy consumption (respiration) decrease with age resulting in an overall decrease in growth rates.
Our finding also suggests the forest carbon sink may decrease in the U s. because of the slowdown in forest growth Tang says.
'which is going to turn every part of the alga into something useful. Algae are known for their ability to convert CO2
This particular alga is able to produce up to 80%of its mass as fuel but is currently too expensive to cultivate for fuel alone.
The Dunaliella alga has been chosen because it produces a wide range of compounds appropriate for the'biorefinery'concept
***Seaweed could be next new biofuelnew research to turn seaweed into liquid biofuel aims to overcome two main barriers to the plant becoming a major source of renewable energy.
and preserve seaweed for year-round use. Ensilage--a method traditionally used by farmers to turn grass into hay for winter animal feed--has potential to stop the seaweed rotting.
The research backed by £1. 6m from the Engineering and Physical sciences Research Council will also explore the conversion of wet seaweed to gas which can in turn be converted to liquid fuel.
There is a global race on to develop the technologies to make seaweed a viable source of green power.
Professor Harvey explains The alga is simply freeze-dried and put in a capsule. So when someone takes it as a vitamin supplement they are also consuming chemicals
