The Marine Macroalgae of Cabo Verde Archipelago: an Updated Checklist
Arquipelago - Life and Marine Sciences ISSN: 0873-4704 The marine macroalgae of Cabo Verde archipelago: an updated checklist DANIELA GABRIEL AND SUZANNE FREDERICQ Gabriel, D. and S. Fredericq 2019. The marine macroalgae of Cabo Verde archipelago: an updated checklist. Arquipelago. Life and Marine Sciences 36: 39 - 60. An updated list of the names of the marine macroalgae of Cabo Verde, an archipelago of ten volcanic islands in the central Atlantic Ocean, is presented based on existing reports, and includes the addition of 36 species. The checklist comprises a total of 372 species names, of which 68 are brown algae (Ochrophyta), 238 are red algae (Rhodophyta) and 66 green algae (Chlorophyta). New distribution records reveal the existence of 10 putative endemic species for Cabo Verde islands, nine species that are geographically restricted to the Macaronesia, five species that are restricted to Cabo Verde islands and the nearby Tropical Western African coast, and five species known to occur only in the Maraconesian Islands and Tropical West Africa. Two species, previously considered invalid names, are here validly published as Colaconema naumannii comb. nov. and Sebdenia canariensis sp. nov. Key words: Cabo Verde islands, Macaronesia, Marine flora, Seaweeds, Tropical West Africa. Daniela Gabriel1 (e-mail: [email protected]) and S.

These included discarded fluorescent tubes, incandescent light bulbs, capped liquor bottles, and ball-shaped fishing-net floats. Field collections and unialgal cultures of the alga revealed that it consisted of two morphological phases: a young loosely aggregated turf and a mature consolidated mucilaginous crust. The turf phase consisted of a basal layer of globose cells that produced erect, rarely branched, uniseriate to multiseriate filaments up to 500 µm long with closely spaced cells lacking pit-plugs. These filaments expanded in size from their bases to their tips and released single cells as spores. At maturity, a second phase of growth occurred that produced a consolidated crust, up to 370 µm thick. It consisted of a basal layer of small, tightly appressed ellipsoidal-to-elongate cells that generated a mucilaginous perithallial matrix containing a second type of filament with irregularly spaced cells often undergoing binary division. -

A Metabarcoding Framework for Facilitated Survey of Endolithic Phototrophs with Tufa Thomas Sauvage1*, William E
Sauvage et al. BMC Ecol (2016) 16:8 DOI 10.1186/s12898-016-0068-x BMC Ecology RESEARCH ARTICLE Open Access A metabarcoding framework for facilitated survey of endolithic phototrophs with tufA Thomas Sauvage1*, William E. Schmidt1, Shoichiro Suda2 and Suzanne Fredericq1 Abstract Background: In spite of their ecological importance as primary producers and microbioeroders of marine calcium carbonate (CaCO3) substrata, endolithic phototrophs spanning both prokaryotic (the cyanobacteria) and eukaryotic algae lack established molecular resources for their facilitated survey with high throughput sequencing. Here, the development of a metabarcoding framework for the elongation factor EF-Ttu (tufA) was tested on four Illumina- sequenced marine CaCO3 microfloras for the characterization of their endolithic phototrophs, especially the abundant bioeroding Ostreobium spp. (Ulvophyceae). The framework consists of novel tufA degenerate primers and a compre- hensive database enabling Operational Taxonomic Unit (OTU) identification at multiple taxonomic ranks with percent identity thresholds determined herein. Results: The newly established tufA database comprises 4057 non-redundant sequences (from 1339 eukaryotic and prokaryotic phototrophs, and 2718 prokaryotic heterotrophs) including 27 classes in 10 phyla of phototrophic diver- sity summarized from data mining on GenBank®, our barcoding of >150 clones produced from coral reef microfloras, and >300 eukaryotic phototrophs (>230 Ulvophyceae including >100 ‘Ostreobium’ spp., and >70 Florideophyceae, Phaeophyceae and miscellaneous taxa). Illumina metabarcoding with the newly designed primers resulted in 802 robust OTUs including 618 phototrophs and 184 heterotrophs (77 and 23 % of OTUs, respectively). Phototrophic OTUs belonged to 14 classes of phototrophs found in seven phyla, and represented ~98 % of all reads. The phylogenetic profiles of coral reef microfloras showed few OTUs in large abundance (proportion of reads) for the Chlorophyta (Ulvo- phyceae, i.e. -

The families Rhodomelaceae and Corallinaceae contain the largest number of species (6 and 5, respectively). Descriptions include morphometric and biological data and are accompanied by photographs and line drawings for each species. Geographic distribution of these algae in the State of Veracruz, park and the Gulf of Mexico are also provided. Polysiphonia pseudovillum is a new record for the Gulf of Mexico, while Colaconema hallandicum and Ceratodictyon planicaule are new records for the park. Nine species have been found as epiphytes mainly on green and red algae. Tetrasporangia were the dominant reproductive structures found in the studied species during both rainy and dry seasons. Vegetative and reproductive thalli of 10 species from the NPSAV were usually smaller compared to those of the same species found in the Caribbean. -
