Preliminary DNA Barcode Report on the Marine Red Algae (Rhodophyta) from the British Overseas Territory of Tristan da Cunha
ABSTRACT The current manuscript is the first in a series intended to publish accumulating DNA barcode data to make them accessible to the scientific community. Focused on 135 specimens of red algae from the remote islands of Tristan da Cunha, part of the British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, the 47 (possibly 48; see notes with Lophurella sp. 1Tris) genetic groups uncovered during this project are compared to the only detailed floristic work for this region completed by Baardseth in 1941. A number of taxonomic anomalies are reported with indications for eventual solutions that await study of the type material of the associated morphospecies. Species previously assigned by Baardseth to the genus Epymenia Kützing are formally transferred to Rhodymenia Greville as R. elongata (Baardseth), comb. nov., (including E. marginifera Baardseth) and R. flabellata (Baardseth), comb. nov. A number of range extensions are reported including species such as Ceramium secundatum (Lyngbye) C.Agardh, Colaconema caespitosum (J.Agardh) Jackelman, Stegenga & J.J.Bolton, Helminthocladia calvadosii (J.V.Lamour. ex Duby) Setch. and Porphyra mumfordii S.C.Lindstrom & K.M.Cole, which have likely been distributed by human activities. We also note that the sporophyte of the supposedly narrowly distributed Schimmelmannia elegans has been collected from both British Columbia, Canada, and Queensland, Australia, consistent with other observations that sporophytes of red algal species with alternations of heteromorphic generations are commonly more broadly distributed than the gametophytic stage. This species, although originally described by Baardseth from these mid Atlantic islands, may also be introduced.
期刊介绍:
Cryptogamie is a fast-track and peer-reviewed journal of international scope publishing in English only. It accepts original papers and review articles on the taxonomy, biology and ecology of all cryptogams. An issue of Cryptogamie may be devoted to a single topic, under the responsibility of guest editor(s). All articles published in Cryptogamie are compliant with the different nomenclatural codes. A copyright assignment will be signed by the authors before publication.
Cryptogamie, Algologie accepts articles on systematics as well as ecology and evolution of any kind of algae (including Cyanobacteria).
