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 ...
It can cause vomiting and diarrhea. [61] The so-called "stinging seaweed" Microcoleus lyngbyaceus is a filamentous cyanobacteria which contains toxins including lyngbyatoxin-a and debromoaplysiatoxin. Direct skin contact can cause seaweed dermatitis characterized by painful, burning lesions that last for days. [1] [62]
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 ]
The closest relatives to animals are the choanoflagellates (~360 species), free-living flagellates that feed through a collar of microvilli surrounding a larger cilium and often form colonies. [115] The Ichthyosporea (>40 species), otherwise known as mesomycetozoans, are a group of fungus-like pathogenic holozoans specialized in infecting fish ...
Its fast growth and size provide an important habitat not only for the fish and invertebrates that reside in kelp forests, but also for species that use kelp forests as foraging grounds. [15] In bull kelp forests, kelp crabs are important grazers that control the ecosystem by feeding on large canopy kelps such as Nereocystis .
Abiotic components include physical conditions and non-living resources that affect living organisms in terms of growth, maintenance, and reproduction. Resources are distinguished as substances or objects in the environment required by one organism and consumed or otherwise made unavailable for use by other organisms.
Plus, some tips for cooking kelp. A nutrition pro highlights kelp's dietary health benefits, including essential nutrients and a potential metabolism boost. Plus, some tips for cooking kelp.
The fly oviposits in dead kelp that washes up on beaches. [8] This is the only place it lays eggs, and it can do so on many species of kelp and seaweed, [9] including species of Laminaria and Fucus. [10] A female fly lays up to five clutches of 80 eggs each. [11] The larvae feed upon the bacteria coating the dead kelp. [9] The life cycle is ...
