Abstract

 During visits to several localities on the South Shetland Islands and the Antarctic Peninsula in summer 1994 we made collections of marine benthic algae. Among the algae we collected were three new records for Antarctica [Petalonia fascia (OF Müller) Kuntze; Enteromorpha intestinalis (L.) Nees; Rhodymenia subantarctica Ricker] and seven other species [Scytosiphon simplicissimus (Clemente) Cremades; Chordaria linearis (Hooker et Harvey) Cotton; Halopteris obovata (Hooker et Harvey) Sauvageau; Acrosiphonia arcta (Dillwyn) J. Agardh; Enteromorpha compressa (L.) Nees; Bangia atropurpurea (Roth) C. Agardh; Porphyra plocamiestris Ricker] that had been reported on only one or two previous occasions (or, in one case, three). The ten species detailed in this paper fall into two groups: four species previously known from sub-Antarctic islands and/or locations in southern South America, and six species having a wider distribution in temperate regions. We discuss the possibility that the less accessible subtidal habitats of some species may have prevented earlier discovery. Other species may be comparatively recent adventives, most likely introduced with shipping. In view of possible global climate changes, species of this latter group are regarded as suitable organisms for monitoring changes of water temperature.
