List of brown seaweeds of the Cape Peninsula and False Bay
Regional biodiversity species list From Wikipedia, the free encyclopedia
This is a list of brown seaweeds recorded from the oceans bordering The Cape Peninsula in South Africa from Melkbosstrand on the West Coast to Cape Hangklip on the South Coast.
This list comprises locally used common names, scientific names with author citation and recorded ranges. Ranges specified may not be the entire known range for the species, but should include the known range within the waters surrounding the Republic of South Africa.
Map of the Cape Peninsula and False Bay coastline showing some of the landmarks referred to in species range statements. Melkbosstrand is a few kilometers north of the displayed area on the west coast. Cape Hangklip is shown on the map to the south east.Marine ecoregions of the South African exclusive economic zoneMap of the Southern African coastline showing some of the landmarks referred to in species range statements.
The marine ecology is unusually varied for an area of this size, as a result of the meeting of two major oceanic water masses near Cape Point, and the park extends into two coastal marine bioregions. The ecology of the west or "Atlantic Seaboard" side of the Cape Peninsula is noticeably different in character and biodiversity to that of the east, or "False Bay" side. Both sides are classified as temperate waters, but there is a significant difference in average temperature, with the Atlantic side being noticeably colder on average.[1]
List ordering and taxonomy complies where possible with the current usage in Algaebase, and may differ from the cited source, as listed citations are primarily for range or existence of records for the region.
Sub-taxa within any given taxon are arranged alphabetically as a general rule.
Details of each species may be available through the relevant internal links. Synonyms may be listed where useful.
