Abstract The green plants (Viridiplantae) are an ancient group of eukaryotes comprising two main clades: the Chlorophyta, which includes a wide diversity algae and Streptophyta, consists freshwater land plants. early-diverging lineages Viridiplantae comprise unicellular multicellularity has evolved independently in clades. Recent molecular data have revealed unrecognized lineage plants, Palmophyllales, with unique form typically found deep water. phylogenetic position this enigmatic group,...
Taxonomy of the brown algal genus Dictyota has a long and troubled history. Our inability to distinguish morphological plasticity from fixed diagnostic traits that separate various species severely confounded delineation. From continental Europe, more than 60 intraspecific taxa have been described over last two centuries. Using molecular approach, we addressed diversity in European waters made necessary taxonomic changes. A densely sampled DNA data set demonstrated presence six...
Sequencing mitochondrial and chloroplast genomes has become an integral part in understanding the genomic machinery phylogenetic histories of green algae. Previously, only three (Oltmannsiellopsis viridis, Pseudendoclonium akinetum, Bryopsis hypnoides) two (O. viridis P. akinetum) from class Ulvophyceae have been published. Here, we present first ecologically economically important marine, algal genus Ulva. The genome Ulva sp. was 99,983 bp a circular-mapping molecule that lacked inverted...
Many tropical marine cyanobacteria are prolific producers of bioactive secondary metabolites with ecological relevance and promising pharmaceutical applications. One species chemically rich, that was previously identified as Symploca hydnoides or sp. corresponds to the traditional taxonomic definition Phormidium penicillatum . In this study, we clarified taxonomy biomedically ecologically important cyanobacterium by comparing recently collected specimens original type material description P....
Abstract Seagrasses are among the most productive habitats in marine realm, performing several crucial physical and biological ecosystem services. One group of seagrasses is family Zosteraceae, which includes three to four genera >20 species inhabiting temperate waters both northern southern hemisphere. Species delineation depends on type data used, ranging from morphological molecular. The main goal this study was better understand evolution divergence within family, using a broad taxon...
Cyanobacteria comprise an extraordinarily diverse group of microorganisms and, as revealed by increasing molecular information, this biodiversity is even more extensive than previously estimated. In sense, the cyanobacterial genus Lyngbya a highly polyphyletic composed many unrelated taxa with morphological similarities. study, new Dapis was erected from Lyngbya, based on combined molecular, chemical, and approach. Herein, two species cyanobacteria are described: D. pleousa pnigousa. Our...
Abstract Aim Historical processes that shaped current diversity patterns of seaweeds remain poorly understood. Using Dictyotales, a globally distributed order brown as model, we test if historical biogeographical and diversification are comparable across clades. Dictyotales contain some 22 genera, three which, Dictyota , Lobophora Padina exceptionally diverse. Specifically, whether the evolutionary latitudinal in these clades line with tropical conservatism, out‐of‐the‐tropics or rate...
Many tropical marine macroalgae are reported from all three ocean basins, though these very wide distributions may simply be an artifact resulting inadequate taxonomy that fails to take into account cryptic diversity. Alternatively, pantropical challenge the belief of limited intrinsic dispersal capacity seaweeds and effectiveness north-south oriented continents as barriers. We aimed re-assess distribution two allegedly circumtropical brown algae, Dictyota ciliolata D. crenulata, interpret...
Coexistence in a homogeneous environment requires species to specialize distinct niches. Sympatry of cryptic is special interest both ecologists and evolutionary biologists because the mechanisms that facilitate their persistent coexistence are obscure. In this study, we report on two sympatric Dictyota species, D. dichotoma (Huds.) J. V. Lamour. newly described cymatophila sp. nov., from Canary Islands. Gene sequence data ( rbc L, psb A, nad 1, cox 3, LSU rDNA) demonstrate do not represent...
Tronholm A., Afonso-Carrillo J., Sansón M., Leliaert F., Fernández-García C., and De Clerck O. 2013. Taxonomy of the Dictyota ciliolata–crenulata complex (Dictyotales, Phaeophyceae). Phycologia 52: 171–181. DOI: 10.2216/12-005.1We reassessed taxonomy dentate species formerly attributed to D. ciliolata crenulata. Both taxa have long been assumed be broadly distributed in tropical warm-temperate seas. Recent molecular data, however, provided evidence that crenulata constituted a at least four...
Abstract Although it has been suggested that the distribution of Dictyota dichotoma is probably restricted to European Atlantic Ocean and Mediterranean Sea, its occurrence in Canary Islands (new southernmost limit) confirmed by nuclear ribosomal sequence data (LSU rDNA). Even though D. described illustrated prominently early studies brown algae, species remains difficult characterize due considerable morphological plasticity. An exhaustive analysis several quantitative characters confirms...
Caribbean coral reefs are experiencing a shift to algal dominance at the expense of stony corals. Determining factors leading phase shifts is crucial for assuring survival reefs. In this study, controlling growth abundant brown macroalgae Dictyota spp. were investigated by varying herbivory pressure (caging) and nutrients (fertilizer addition) on near St. Thomas (US Virgin Islands). Experiment 1 measured heights percent cover 3 sites (11-20 m depth) showed no response nutrient addition weak...
The control of RNA splicing is often modulated by exonic motifs near splice sites. Chief among these are enhancers (ESEs). Well-described ESEs in mammals purine rich and cause predictable skews codon amino acid usage toward ends. Looking across species, those with relatively abundant intronic sequence the more profound end exon skews, indicative exonization site recognition. To date, only intron-rich species that have been analyzed mammals, precluding any conclusions about likely ancestral...
Abstract Sargassum species play a key role in habitat formation tropical and subtropical regions; however, identification has been hampered by the phenological plasticity exhibited response to environmental conditions life history. Molecular phylogenetics challenged taxa circumscriptions proven critical delimiting this genus. Yet, Atlantic of remain poorly understood, recent studies have shown low molecular diversity between NW Atlantic. Here, we expand taxon sampling NE assess basin, based...
Environmental and human factors are inducing a drastic decline in many marine algae regions with high floristic richness as the Canary Islands. Simultaneously, undescribed algal species continue to be discovered, suggesting probable loss diversity, before being properly identified catalogued. Turf-forming Gelidiales occur littoral communities from tropical warm temperate challenging identify correctly because of their small size simple morphology. In present study, we combined morphological...
Every introduction of a non-indigenous species (NIS) in coastal environments poses threat to the native and communities, as its effects ecosystem are not readily predictable. Introduction rates have kept increasing last decades, our finding brown alga Mutimo cylindricus Canary Islands is another example this general trend. This work represents first record outside range (Japan, Korea Philippines) half century, since report 1973 Baja California, marks M. Atlantic Ocean. We analyzed morphology...
