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 ]
Kelp forests are also some of the world's largest carbon sinks, and the Great Southern Reef therefore acts as a buffer against climate change. [7] Unfortunately, an estimated 95% of the giant kelp forests off the coast of Tasmania have died off over the past few decades due higher water temperatures and the long-spined sea urchin. [6] [8]
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 productive ecosystems in the world - they are home to a great diversity of species. Many groups, like those at the Seattle Aquarium , are studying the health, habitat, and population trends in order to understand why certain kelp (like bull kelp ) thrives in some areas and not others.
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.
Dymaxion world map with the 15 largest lakes roughly to scale. This is a pair of lists of terrestrial lakes with a surface area of more than approximately 3,000 square kilometres (1,200 sq mi), ranked by area, [1] [2] [3] excluding reservoirs and lagoons.
A welding hammer strapped to her wrist, Joy Hollenback slipped on blue fins and swam into the churning, chilly Pacific surf one fall morning to do her part to save Northern California's vanishing ...
It usually stays near kelp forests, drop-offs, or rocky bottoms and sand or mudflats. [8] Juvenile giant sea bass can be found at depths around 69 feet (21 m), with adults of the species found at depths below 66 feet (20 m). [9] Juveniles of the species are brightly colored in red or orange, however they become gray or brown as they mature. [10]
