[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 occur worldwide throughout temperate and polar coastal oceans. [1] In 2007, kelp forests were also discovered in tropical waters near Ecuador. [4]
A top-down cascade is a trophic cascade where the top consumer/predator controls the primary consumer population. In turn, the primary producer population thrives. The removal of the top predator can alter the food web dynamics. In this case, the primary consumers would overpopulate and exploit the primary producers. Eventually there would not ...
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 ...

“Kelp forms whole forests that are supporting so many other species and so it just has this cascading effect on the near-shore ecosystem when you lose your kelp,” Elsmore said. “You’re ...
Secondary consumers such as the Kelp Bass may soon follow. [16] A similar chain reaction can occur if industrial waste or sewage runs off into the ocean and poisons the kelp. [17] Kelp forests along the west coast are also threatened by invasive species such as Strongylocentrotus purpuratus (Purple Sea Urchins).
Kelp farming has the potential to fortify the planet against a changing climate and also creates a regenerative industry led by Native peoples and communities. Reclaiming Native Knowledges Through ...
More than 100,000 mobile invertebrates per square meter are found on kelp stipes and holdfasts in well-developed kelp forests. [30] While larger invertebrates and in particular sea urchins ( Strongylocentrotus droebachiensis ) are important secondary consumers controlling large barren ground areas on the Norwegian coast, they are scarce inside ...
