A Rhapsody of new Red Algal Records in Thailand
Draisma, Stefano; Muangmai, Narongrit; Gabriel, DanielaABSTRACT: Recent explorations in Thai waters have resulted in the discovery of red algae that represents new records for the Thai seaweed flora, including species putatively new to science. Preliminary identifications are primarily based on newly generated DNA-sequence data (COI, rbcL, rDNA LSU, UPA) that were compared to genetic sequences in public databases and unpublished datasets. New genus records for Thai...
What lies beneath - Southeast Asia’s hidden seaweed diversity
Draisma, Stefano; Gabriel, Daniela; Liu, Shao Lun; Lim, Phaik EemABSTRACT: Southcast Asia is a marine biodiversity hotspot. Assessmentes of marine flora diversity in the region are traditionaly based on the morphological species concept. However, several molecular studies have revealed that there is more species diversity in scaweeds than the naked eye can see.
Genetic diversity of Gibsmithia hawaiiensis complex (Dumontiaceae, Rhodophyta)
Gabriel, Daniela; Draisma, Stefano; Schmidt, William E.; Schils, Tom; Sauvage, Thomas; Maridakis, Clio; Gurgel, Carlos Frederico Deluqui; Lim, Phaik EemABSTRACT: The genus Gibsmithia was erected to accommodate a species with the peculiar combination of gelatinous lobes rising from cartilaginous stalks. Based on G. hawaiiensis from Hawaii, it remained monotypic for over 20 years, when three additional species were described from Australia. G. hawaiensis is unique for its furry appearance due to cortical filaments beyond the surface. Gibsmithia have been reporte...
Genetic diversity of Gibsmithia hawaiiensis complex (Dumontiaceae, Rhodophyta):...
Gabriel, Daniela; Draisma, Stefano; Sauvage, Thomas; Schmidt, William; Fredericq, SuzanneABSTRACT: The genus Gibsmithia was erected on the basis of G. hawaiiensis Doty 1963 from the Hawaiian archipelago to accommodate a species of red algae in the Dumontiaceae consisting of clusters of gelatinous lobes growing from a cartilaginous stalk. Three additional species were subsequently described from Australia, i.e. G. dotyi Kraft & R.W. Ricker 1984, G. larkumii Kraft 1986 and G. womersleyi Kraft & Ricke...
Taxonomic studies in the Schizymeniaceae (Nemastomatales, Rhodophyta): on the i...
Gabriel, Daniela; Schils, Tom; Parente, Manuela I.; Draisma, Stefano; Neto, Ana I.; Fredericq, SuzanneComparative rbcL sequence analysis indicates that the species going under the name Schizymenia dubyi in the Azores should be referred to as S. apoda. Sequences of Schizymenia specimens from China and Namibia were also identified as S. apoda, of which the type locality is the Cape Province in South Africa. Schizymenia dubyi, described from Atlantic France, is clearly a distinct species that we here report for Ja...
Life history and morphological studies of Punctaria tenuissima (Chordariaceae, ...
Parente, Manuela I.; Fletcher, Robert L.; Neto, Ana I.; Tittley, Ian; Sousa, Ana F.; Draisma, Stefano; Gabriel, DanielaPunctaria tenuissima (Chordariaceae, Phaeophyceae) is reported for the first time from the Azores. Erect thalli were collected on the Island of Sa˜o Miguel; they were up to 3 cm long, flattened and often twisted. The plurilocular sporangia were formed from surface cells that were quadrate or rectangular in surface view. Unilocular sporangia were not observed in the field. In culture, the plurispores of P. tenui...
