Algae
- Kelp are actually large brown algae that live in cool, relatively shallow waters close to the shore. They grow in dense groupings much like a forest on land. These underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

Are marine protists unicellular or multicellular?
Marine protists are defined by their habitat as protists that live in marine environments, that is, in the saltwater of seas or oceans or the brackish water of coastal estuaries. Life originated as marine single-celled prokaryotes (bacteria and archaea) and later evolved into more complex eukaryotes. Eukaryotes are the more developed life forms ...

The bacterial communities associated with seaweeds have been shown to be structured over a range of spatial scales, including microns , centimetres , tens , thousands and tens of thousands of kilometres . In the most geographically extensive study to date, Bonthold et al. (2020) explicitly examined the relative importance of different spatial scal...
Despite high between-host variation, consistencies were observed across all the spatial scales of our study. At a coarser taxonomic resolution, out of the 52 classes we observed, the vast majority of sample abundance was constrained to Alphaproteobacteria, Gammaproteobacteria, Planctomycetes and Bacteroidia. Whilst we do not have appropriate enviro...
The “core community” concept aims to identify stable, functionally important taxa rather than transient or opportunistic components of the community . In this study, both kelp hosts possessed a small core community that was similar in size and composition. The ASVs that were present in > 80% of samples made up 25.4% (L. hyperborea – 11 ASVs) and 32...
We observed no difference in community structure between associated bacterial communities of L. hyperborea and S. latissima, with these two hosts sharing 40% of observed ASVs. This is similar to the 37% of bacterial taxa shared between eight sympatric kelp hosts in British Columbia . Moreover, many of the most diverse families observed in our study...
Giant kelp (Macrocystis pyrifera), which is found along the shorelines of the Pacific Coast, is one of the most impressive brown algal protists. It can grow up to two feet in one day, and as long ...

Marine microorganisms are defined by their habitat as microorganisms living in a marine environment, that is, in the saltwater of a sea or ocean or the brackish water of a coastal estuary. A microorganism (or microbe) is any microscopic living organism or virus, which is invisibly small to the unaided human eye without magnification ...
Aug 25, 2023 · Kelps (brown algae) are the only multicellular protists. Protist (biology definition): Any of a group of eukaryotic organisms belonging to the Kingdom Protista. Protists include: (1) protozoa, the animal-like protists, (2) algae, the plant-like protists, and (3) slime molds and water molds, the fungus-like protists.
Sep 4, 2019 · Densely packed and able to reach heights of over 90 feet, kelp forests provide food, shelter, and protection to many marine organisms. But while their importance in our oceans is well documented, they might still be hiding their best kept secret: microbes.
