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.
This "kelp highway hypothesis" suggested that highly productive kelp forests supported rich and diverse marine food webs in nearshore waters, including many types of fish, shellfish, birds, marine mammals, and seaweeds that were similar from Japan to California, Erlandson and his colleagues also argued that coastal kelp forests reduced wave ...
The Giant kelp marine forests of south east Australia is a community extending from the ocean floor to the ocean surface, on a rocky substrate, and has a ‘forest-like’ structure with many organisms occupying its various layers, including pelagic and demersal fishes, sea birds, turtles and marine mammals in addition to the invertebrate ...
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 ...
Harvesting of kelp as a food source and other uses may be the least concerning aspect to its depletion. In the Northwest Pacific kelp forests in waters near large population centres may be most affected by the sewer/stormwater discharge. [51] The natural phenomenon known as El Niño cycles warm, tropical water from the South Pacific to Northern ...
The team of divers was training in the giant kelp forests of eastern Santa Cruz Island in California’s Channel Islands National Park.
Frequently considered an ecosystem engineer, kelp provides a physical substrate and habitat for kelp forest communities. [50] In algae (Kingdom: Protista), the body of an individual organism is known as a thallus rather than as a plant (Kingdom: Plantae). The morphological structure of a kelp thallus is defined by three basic structural units: [49]
TIL ecologist Suzanne Simard wanted to know why the forest got sick every time the foresters k****d the birch trees, thought to harm fir trees. She discovered that birch trees actually pass ...
