In Alaskan kelp forest ecosystems, sea otters are the keystone species that mediates this trophic cascade. In Southern California, kelp forests persist without sea otters and the control of herbivorous urchins is instead mediated by a suite of predators including lobsters and large fishes, such as the California sheephead.
“The bull kelp forest that runs along the Oregon coast is a stunningly beautiful and vitally important ecosystem,” says Alanna, who studied biology with a focus on marine science at Oregon ...
Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf and lion, are also apex predators. The role that a keystone species plays in its ecosystem is analogous to the role of a keystone in an arch. While the keystone is under the least pressure of any of the ...
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.
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 ...
Beavers are the prototypical ecosystem engineer because of the effects their dams have on channel flow, geomorphology, and ecology. Kelp are autogenic ecosystem engineers, by building the necessary structure for kelp forests. An ecosystem engineer is any species that creates, significantly modifies, maintains or destroys a habitat.
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]
Giant kelp grows in dense stands known as kelp forests, which are home to many marine animals that depend on the algae for food or shelter. The primary commercial product obtained from giant kelp is alginate , but humans also harvest this species on a limited basis for use directly as food.
