Abstract Ulva, one of the first Linnaean genera, was later circumscribed to consist green seaweeds with distromatic blades, and Enteromorpha Link established for tubular forms. Although several lines evidence suggest that these generic constructs are artificial, Ulva have been maintained as separate genera. Our aims were determine phylogenetic relationships among taxa currently attributed Enteromorpha, Umbraulva Bae et I.K. Lee monotypic genus Chloropelta C.E. Tanner, make any nomenclatural...
Global climate change is having a significant effect on the distributions of wide variety species, causing both range shifts and population extinctions. To date, however, no consensus has emerged how these processes will affect range-wide genetic diversity impacted species. It been suggested that species recolonized from low-latitude refugia might harbour high levels variation in rear-edge populations, loss populations could cause disproportionately large reduction overall such taxa. In...
The assembly of the tree life has seen significant progress in recent years but algae and protists have been largely overlooked this effort. Many groups ancient roots it is unclear how much data will be required to resolve their phylogenetic relationships for incorporation life. red algae, a group primary photosynthetic eukaryotes more than billion old, provide earliest fossil evidence eukaryotic multicellularity sexual reproduction. Despite evolutionary significance, are understudied. This...
"Green tides" are vast accumulations of unattached green macroalgae associated with eutrophicated marine environments. They have major ecological and economic impacts globally, so an understanding their origin persistence is required in order to make management decisions. Blooms predominantly consist two common fouling genera the Ulvales, Ulva (distromatic sheets) Enteromorpha (monostromatic tubes). In Baltic Sea elsewhere tides increased over last few decades. On west coast Finland, summer...
Abstract Phylogeography has provided a new approach to the analysis of postglacial history wide range taxa but, date, little is known about effect glacial periods on marine biota Europe. We have utilized combination nuclear, plastid and mitochondrial genetic markers study biogeographic red seaweed Palmaria palmata in North Atlantic. Analysis nuclear rDNA operon (ITS1‐5.8S‐ITS2), 16S‐ trn I‐ A‐23S‐5S, rbc L‐ S rpl 12‐ rps 31‐ 9 regions cox 2–3 spacer revealed existence previously unidentified...
Ulva and Enteromorpha are two of the most common, ubiquitous, environmentally important genera green seaweeds. They widely regarded as easily distinguishable because their dramatically different morphologies: species flat, lettucelike blades cell layers thick, form hollow liquid- or gas-filled tubes one which may also be highly branched. We present molecular phylogenetic analyses nuclear ribosomal RNA ITS sequences from 39 samples representing 21 purported within these genera. The results...
The very common green seaweeds Enteromorpha intestinalis (L.) Nees and E. compressa are important fouling organisms have commonly been used as indicators of eutrophication, but their taxonomic status is problematic. genus presents extreme difficulties because there wide intraspecific variation in morphology, morphological differences between species small difficult to detect. In this study, molecular data were parallel with characters resolve the problems. Phylogenetic analysis sequences...
Abstract In Europe, the last 20 years have seen a spectacular increase in accidental introductions of marine species, but it has recently been suggested that both actual number invaders and their impacts seriously underestimated because prevalence sibling species habitats. The red alga Polysiphonia harveyi is regarded as an alien British Isles Atlantic having appeared various locations there during past 170 years. Similar or conspecific populations are known from North America Japan. To...
Maerl is a type of rhodolith, found in ecologically important beds high conservation value; major objective to establish growth rates. shows internal banding controversial periodicity that may contain high-resolution record palaeoceanographic-palaeoclimatic data. To investigate rates and periodicity, we used the vital stain Alizarin Red combination with scanning electron microscopy (SEM). Three maerl species, Phymatolithon calcareum, Lithothamnion corallioides L. glaciale, were collected...
Abstract The spread of nonindigenous species into new habitats is having a drastic effect on natural ecosystems and represents an increasing threat to global biodiversity. In the marine environment, where data movement invasive scarce, alien seaweeds particular problem. We have employed combination plastid microsatellite markers DNA sequence from three regions genome trace history green alga Codium fragile ssp. tomentosoides . Extremely low levels genetic variation were detected, with only...
Abstract The rhodophyte seaweed Asparagopsis armata Harvey is distributed in the northern and southern temperate zones, its congener taxiformis (Delile) Trevisan abounds throughout tropics subtropics. Here, we determine intraspecific phylogeographic patterns to compare potential causes of disjunctions distributions both species. We obtained specimens their ranges inferred phylogenies from hypervariable domains D1‐D3 nuclear rDNA LSU, plastid spacer between large small subunits RuBisCo...
ABSTRACT With the advent of ‘ancient DNA’ studies on preserved material extant and extinct species, museums herbaria now represent an important although still underutilized resource in molecular ecology. The ability to obtain sequence data from archived specimens can reveal recent history cryptic species introductions. We have analysed herbarium samples highly invasive green alga Codium fragile , many over 100 years old, identify accessions strain known as C. ssp. tomentosoides which be...
With over a thousand species, the Rhodomelaceae is most species-rich family of red algae. While its genera have been assigned to 14 tribes, high-level classification has never evaluated with molecular phylogeny. Here, we reassess by integrating genome-scale phylogenetic analysis observations morphological characters clades. In order resolve relationships among main lineages constructed phylogeny 55 chloroplast genomes (52 newly determined). The majority branches were resolved full bootstrap...
