In development since 1996, AlgaeBase (http//www.algaebase.org) is an on-line database providing free access to authoritative taxonomic, distributional and nomenclatural information of more than 135,000 names species infraspecific taxa algae set in the context a taxonomic hierarchy. The project was initially funded by Higher Education Authority, Department Science (Ireland) European Union (the SeaweedAfrica Project), recently industry sponsor Ireland (Ocean Harvest Technology) various...
Maerl beds are sensitive biogenic habitats built by an accumulation of loose-lying, non-geniculate coralline algae. While these considered hot-spots marine biodiversity, the number and distribution maerl-forming species is uncertain because homoplasy plasticity morphological characters common. As a result, discrimination based on features notoriously challenging, making algae ideal candidates for DNA barcoding study. Here, mitochondrial (COI-5P barcode fragment) plastidial (psbA gene)...
Abstract Methylene Blue adsorption on Sargassum muticum , an invasive macroalga in Europe, has been investigated using visible absorption spectroscopy. Different pre‐treatments, protonation and chemical cross‐linking with CaCl 2 or H CO, have tested order to improve the stability as well capacity of algal biomass. The equilibrium binding described terms Langmuir Freundlich isotherms depending pre‐treatment; from maximum values, estimation specific surface area was made. Moreover, it found...
Abstract The northern Portuguese coast is a biogeographic transition zone where many macroalgal species have their distribution limits; it thus particularly interesting region for investigating shifts. An updated and complete list of this not available in spite its baseline importance comparative studies with past present data. Based on new records, literature references, herbarium data, we provide an checklist the benthic marine algae coast. This includes 346 species: 26 Cyanobacteria, 200...
Glacial vicariance is regarded as one of the most prevalent drivers phylogeographic structure and speciation among high-latitude organisms, but direct links between ice advances range fragmentation have been more difficult to establish in marine than terrestrial systems. Here we investigate evolution largely disjunct (and potentially reproductively isolated) lineages within amphi-boreal kelp Saccharina latissima s. l. Using molecular data (COI, microsatellites) confirm that S. comprises also...
Grateloupia filicina (C. Agardh) Lamouroux, originally described from the Mediterranean Sea, has long been considered a textbook example of marine red alga with cosmopolitan distribution. An rbc L‐based molecular phylogeny, encompassing samples covering entire geographic distribution species, revealed plethora “cryptic” whereby presence genuine G. is limited to basin. The phylogeny strong biogeographic imprint, specimens temperate regions resolved in clades composed species inhabiting same...
For the first time, a comprehensive assessment of Mesophyllum species diversity and their distribution in Atlantic Europe Mediterranean Sea is presented based on molecular (COI-5P, psbA) morphological data. The ranges were redefined for four collected this study: M. alternans, expansum, macroblastum sphaericum. sphaericum, which was previously known only from single maerl bed Galicia (NW Spain), reported Sea. range expansum (Mediterranean Macaronesia) extended to Iberian Peninsula....
Two non-geniculate coralline red algae (Lithothamnion corallioides and Phymatolithon calcareum) are partially protected under the assumption that they main components of maerl beds in Atlantic Europe. However, what we know about composition relies mainly on morphology-based identifications notoriously difficult due to a lack diagnostic features, convergence, widespread phenotypic plasticity. Now, this state affairs can be improved with new alternatives that, unlike morphology, allow...
We present an annotated checklist of the benthic marine and brackish algae Galician coasts (Spain) based on literature records new collections.This includes 618 species: 118 Cyanophyta, 296 Rhodophyta, 127 Ochrophyta, 77 Chlorophyta.The number specific, infraspecific taxa, stages is 643: 121 309 135 79 Chlorophyta.Hyella caespitosa var.nitida, Calothrix fasciculata, Gracilariopsis longissima, Compsonema minutum, Sphacelaria tribuloides are for Galicia, there also some provincial records.We...
Phymatolithon lusitanicum is a new maerl species described based on an integrative systematic approach including molecular (COI-5P, psbA) and morphological data obtained from recent collections, as well comparison of type material the morphologically ecologically alike NE Atlantic P. lamii laevigatum. Molecular analyses laevigatum were congruent in delimiting independent lineage these crustose species. The three shared common external morphology multiporate asexual conceptacles, but has been...
Abstract. The analysis of biological and ecological traits has a long history in evolutionary research. However, trait data are often scattered standardised terminology that transcends taxonomic biogeographical context generally missing. As part the development global database marine species, we collated information for European seaweeds structured within framework World Register Marine Species (WoRMS). We collected 45 175 records 21 biologically ecologically relevant seaweeds. This resulted...
Effective monitoring of non-indigenous seaweeds and combatting their effects relies on a solid confirmation the status respective species. We critically analysed presumed seaweed species reported from Mediterranean Sea, Northeast Atlantic Ocean Macaronesia, resulting in list 140 whose nature is undisputed. For an additional 87 it unclear if they are native or (cryptogenic species) identity requires (data deficient species). discuss factors underlying both taxonomic biogeographic...
Abstract We studied the conservation status of a maërl bed off Benencia Island (NW Spain) over 2-year period using SCUBA and dredging. The bed, which includes beach, extended from intertidal to subtidal zones (18 m), occupied an area 215 ha. It was composed pure unattached coralline algal deposit occasionally mixed with broken shells. estimated for highest cover (76–100%) greater than reported in previous research. living layer reached 15 cm depth living/dead ratio high (80–100% cover)....
Mesophyllum sphaericum sp. nov. is described based on spherical maërl individuals (up to 10 cm) collected in a shallow subtidal bed Galicia (NW Spain). The thalli of these specimens are radially organized, composed arching tiers compact medullary filaments. Epithallial cells have flattened rounded outermost walls, and they occur single layer. Subepithallial initials as long as, or longer than the daughter that subtend them. Cell fusions abundant. Multiporate asexual conceptacles protruding,...
Fertile gametangial plants of Phymatolithon calcareum, which are seldom reported in the Atlantic European coasts, were collected as encrusting, epilithic a subtidal maerl bed Brittany (France). Based on their morphological features, identified P. calcareum. This identification was further confirmed by DNA barcodes using reference COI-5P sequences obtained from neotype together with recent collections beds. The reproductive structures empty but they regarded mature female conceptacles....
A study of three shallow Atlantic maërl beds (3–6 m depth) in NW Spain (Galicia) sampled every 1.5 months for a year. At each site, temporal variation the associated flora and two parameters, temperature photosynthetic photon flux density (PPFD), were recorded situ means calculated period. The range mean periodic temperatures was 11.9–17.5°C, increasing late spring–summer decreasing to <12°C winter. Mean PPFD 24–160 µmol photons m−2 s−1; maximum spring (up 571 s−1). correlated with seasonal...
