Native and non-native species of hard substrata in the Dutch Wadden Sea
Bij een inventarisatie van hard substraat in 83 locaties in de Nederlandse Waddenzee, in zoutgehaltes van 10-32 ppt, werden in juli/augustus 2009 in totaal 129 soorten planten en dieren waargenomen.…
Hull fouling on commercial ships as a vector of macroalgal introduction
In the light of the present results, hull fouling on standard trading commercial vessels does not seem to pose a significant risk for new macroalgal species introductions, however, a high proportion of non-cosmopolitan species found on a ship with non-toxic coating may modify this assessment.
Where is the western limit of the tropical Indian Ocean seaweed flora? An analysis of intertidal seaweed biogeography on the east coast of South Africa
New, large-scale collections have been made of marine benthic macroalgae (seaweeds) on the east coast of South Africa, and the distributions of shallow-water species were analyzed in detail by…

Red algal exotics on North Sea coasts
Many of the alien red algae in the North Sea contain anti-grazing compounds such as bromophenols, which may contribute to their invasive potential by deterring grazing sufficiently to permit establishment of an inoculum.
Seaweed species diversity in South Africa
A dataset is presented on the diversity of South African seaweed species and their distribution in contiguous 50-km coastal sections, to demonstrate current knowledge of the flora in various coastal…
Subtidal Algal Communities at Bird Island, Eastern Cape, South Africa
The subtidal algae of the eastern Cape, South Africa, are poorly known and subtidal communities in this area have not been investigated before, so there is almost no information on the which lies near Port Elizabeth, and within the south subtidal algal communities occurring off the coast of coast marine province.

Three of these red macroalgae new to Europe are likely to have been introduced after 2008, indicating some active transport pathways between the Pacific and the north-eastern Atlantic and underline the importance of consistent and continuous local expertise in early warning systems.

The marine algae of Hluleka (Transkei) and the warm temperate/sub-tropical transition on the east coast of southern Africa
The marine flora of the transition region between the warm temperate south coast and sub-tropical east coast of southern Africa is very poorly documented. The seaweeds of Hluleka Nature Reserve,…
