Ascophyllum nodosum is an autotroph, meaning that it makes its own food by photosynthesis, like other plants and algae. The air bladders on A. nodosum serve as a flotation device, which allows sunlight to reach the plant better, aiding photosynthesis. [6] Epiphytic red algae on knotted wrack at Roscoff, France
Pelvetia canaliculata, the channelled wrack, [2] is a very common brown alga (Phaeophyceae) found on the rocks of the upper shores of Europe. It is the only species remaining in the monotypic genus Pelvetia .
Brawley's early research examined the biology of the brown algae Fucus and macroalgal reproductive ecology, [3] [4] [5] and the role of grazers in determining community structure on coral reefs. [6] In the rocky intertidal zone, Brawley has modeled fertilization and the physical transport of gametes from algae. [ 7 ]
Fucus cottonii, also known as moss wrack, is a species of brown algae that grows in low energy salt-marsh environments on Atlantic and Pacific coasts. The algae is small in comparison to other members of the Fucus genus and lacks the bladders common in other species, such as Fucus vesiculosus (bladder wrack).
Algal Research is a bimonthly peer-reviewed scientific journal covering research on emerging technologies in algae biology, biomass production, cultivation, harvesting, extraction, bioproducts, and econometrics that was established in 2012.
The brown algae, including familiar seaweeds like wrack and kelp, are major autotrophs of the intertidal and subtidal marine habitats. [31] Some of the bacterivorous stramenopiles, such as Cafeteria, are common and widespread consumers of bacteria, and thus play a major role in recycling carbon and nutrients within microbial food webs.

“I don’t think trying to live to be 800 is a good way for us to spend our research dollars right now,” says Garrison. In fact, she doesn’t even like the word longevity. It makes her cringe.
Parrish's research has linked dead birds found on the beach with changing seawater off California, [13] the presence of harmful algal blooms, [14] and marine heatwaves. [ 15 ] [ 16 ] Through the collection of data from volunteers, Parrish was able to link recent observations of the by-the-wind sailor jellyfish with seawater conditions off the ...
