Abstract

Subantarctic and Antarctic regions remain little
explored with regards to their seaweed diversity. This
study is based upon collections in the early 1970s and
2007–2013. It is supported by sequencing COI (mitochondrial
cytochrome oxidase I) and reports new records for
four species of brown algae (Hincksia granulosa, Hincksia
sandriana, Myriotrichia clavaeformis, Syringoderma australe),
four red algae (Erythrotrichia carnea, Paraglossum
salicifolium, Phycodrys antarctica, Plumariopsis eatonii),
one green alga (Chaetomorpha aerea) and of the oomycete
Anisolpidium ectocarpii. A further four brown algae
are reported at genus level and discussed (Cladostephus
sp., Colpomenia sp., Dictyota sp., Punctaria sp.). Observations
of the biology of three brown algal taxa (Cladothele
decaisnei, Geminocarpus geminatus, Halopteris obovata)
from the region are also reported here.
