Fucus is a genus of brown algae found in the intertidal zones of rocky seashores almost throughout the world.

Most of the organisms called ‘seaweeds’ are brown algae, although some are red algae and a few are green algae. Like most (but not all) brown algae, Fucus is a large, multicellular organism that well-adapted to life in intertidal and shallow coastal waters, most commonly in …

Fucus are perennial algae, some of which have a life span of up to four years. They feature bladderlike floats (pneumatocysts), disk-shaped holdfasts for clinging to rocks, and mucilage-covered blades that resist desiccation and temperature changes.

Fucus can be described as a genus of brown algae which are mostly seen throughout the world in the intertidal zones of the rocky seashores. Fucus is a large multicellular organism that is most common in relatively cool waters, intertidal and shallow waters, and is well-adapted in life.

2021年10月13日 · Most of the organisms called 'seaweeds' are brown algae, although some are red algae anda few are green algae. Like most (but not all) brown algae, Fucus is a large, multicellular organism that well-adapted to life in intertidal and shallow coastal waters, most commonly in relatively cool waters.

Brown algae are brown due to the large amounts of carotenoids they produce, primarily one called fucoxanthin. These organisms are exclusively multicellular and can get so large that they require special conductive cells to transport photosynthates …

Genus Fucus of Fucaceae: This is a common marine alga containing a number of species that are widely distributed in the sea coasts of temperate and Arctic regions. Most species are found attached to rocks between low and high tide marks and are commonly known as rock- weeds.

2023年3月31日 · In the Pacific Northwest and Alaska (particularly on sheltered shorelines), Fucus is often the dominant species of algae, forming a broad, distinctive band in the mid-intertidal. Synonyms. Fucus gardneri. Similar species. Can be confused with the other common rockweeds: Hesperophycus californicus, Pelvetiopsis limitata, and Silvetia compressa.

Fucus is northern-hemisphere genus of macroscopic marine seaweeds called wracks. It includes a relatively small number of species. Fucus vesiculosus is perhaps the best-known species (below), is known to have a number of useful compounds. The plants consist of a flattened, dichotomously-branched thallus which has a small stipe and a holdfast.

Fucus spp. have high photosynthetic rates, surpassing phytoplankton species on a per-unit, bottom-area basis, and provide settlement substratum, food and shelter for a large number of microbial, algal and animal species (e.g. Kautsky et al., 1992; Middelboe et …
