Free-floating Ulva in the southwest Netherlands: species or morphotypes? A morphological, molecular and ecological comparison
TLDR
Free-floating Ulva L. curvata could be recognized easily because of the characteristic central cavity in the holdfast of the attached plants, the arrangement of cells in rows and the single pyrenoid in each cell, and U. scandinavica usually possessed more pyrenoids. Expand
A REASSESSMENT OF PHYLOGENETIC RELATIONSHIPS WITHIN THE PHAEOPHYCEAE BASED ON RUBISCO LARGE SUBUNIT AND RIBOSOMAL DNA SEQUENCES
To better assess the current state of phaeophycean phylogeny, we compiled all currently available rbcL, 18S, and 26S rDNA sequences from the EMBL/GenBank database and added 21 new rbcL sequences ofExpand
Resolving phenotypic plasticity and species designation in the morphologically challenging Caulerpa racemosa–peltata complex (Chlorophyta, Caulerpaceae)
TLDR
The number of genetic species within the Caulerpa racemosa–peltata complex was determined through a combination of phylogenetic and species‐delimitation approaches of partial elongation factor TU and RUBISCO large subunit gene sequences and names for the lineages were confidently designated. Expand
DNA SEQUENCE DATA DEMONSTRATE THE POLYPHYLY OF THE GENUS CYSTOSEIRA AND OTHER SARGASSACEAE GENERA (PHAEOPHYCEAE) 1
TLDR
Phylogenetic relationships in the Sargassaceae were explored using three DNA markers, and the monophyly of its genera was challenged, and some evolutionary trends could be discerned from the mt23S + psbA phylogeny. Expand
Molecular phylogeny of Macaranga, Mallotus, and related genera (Euphorbiaceae s.s.): insights from plastid and nuclear DNA sequence data.
TLDR
The analyses demonstrated the monophyly of Macaranga and the paraphyly of Mallotus and revealed three highly supported main clades, suggesting migrations or dispersals from Asia to Africa and Madagascar. Expand
Multiple trans-Arctic passages in the red alga Phycodrys rubens: evidence from nuclear rDNA ITS sequences
TLDR
Rooted phylogenetic analyses of nuclear ribosomal DNA internal transcribed spacer (ITS) sequences and the plastid encoded Rubisco spacer sequences suggest that P. rubens invaded the North Atlantic from the Pacific shortly after the opening of the Bering Strait, colonizing both the western and eastern Atlantic coasts. Expand
A phylogenetic study of Boletus section Boletus in Europe
TLDR
Boletus edulis is defined as a variable species with a wide morphological, ecological and geographic range, and includes several specific and subspecific taxa described in the literature and three other European species that are well delimited species based on morphology and genetic data. Expand
Padina ditristromatica sp. nov. and Padina pavonicoides sp. nov. (Dictyotales, Phaeophyceae), two new species from the Mediterranean Sea based on morphological and molecular markers
A study of the genus Padina in the Mediterranean Sea, based on detailed morphological and molecular analyses using chloroplast rbcL and mitochondrial cox3 gene sequences, as well as RuBisCO spacerExpand
Phylogenetic relationships within the Sphacelariales (Phaeophyceae): rbcL, RUBISCO spacer and morphology
TLDR
Blackening in response to bleach and the presence of secondary segments were found to be basal synapomorphies for the Sphacelariales ; presence of propagules with a lenticular central apical cell defines the Propagulifera; and strict acroblastic branching mode and axillary zoidangia define the Stypocaulaceae. Expand
Molecular phylogeny of two unusual brown algae, Phaeostrophion irregulare and Platysiphon glacialis, proposal of the Stschapoviales ord. nov. and Platysiphonaceae fam. nov., and a re‐examination of
TLDR
It is proposed that the development of heteromorphic life histories and their success in the temperate and cold‐water regions was induced by theDevelopment of the remarkable seasonality caused by the breakup of Pangaea. Expand
