The marine algae genus Monostroma (Thuret) consists of some of the common intertidal green seaweeds in the world. However, reports on its interbreeding potential between geographical radiations or its phylogeography are nonexistent. Here, we show that warmwater Monostroma in SW Japan, previously thought to be composed of two morphological species, viz., Monostroma latissimum and Monostroma nitidum, is indeed a single biological species, as revealed by mating tests. Using morphometry and DNA… 
Sympatric speciation in structureless environments
TLDR
An individual-based population model with variable foraging strategies is used to study the evolution of mating behavior among foraging strategy types and demonstrates that sympatric speciation may be more likely than previously thought to occur in mobile, sexually-reproducing organisms.
Phylogenetics: Tracing the Evolutionary Legacy of Organisms, Metastatic Clones, Bioactive Compounds and Languages
TLDR
An invited editorial contributed to the Journal of Phylogenetics and Evolutionary Biology a big picture of this ever evolving field is expounded with a personal perspective summarizing contribution to this interdisciplinary field from the author's group.
Time Calibration of Linguistic Phylograms: A Molecular Clock for Historical Linguistics
TLDR
Proposed in this invited editorial is the direct extension of the molecular clock hypothesis and time-calibration techniques of molecular phylogenetics to the field of phylolinguistics and a call to make use of Maximum Parsimony-based approaches for the ancient character-state reconstruction, for reconstructing long-lost languages.

MOLECULAR DELINEATION OF SPECIES AND SYNGENS IN VOLVOCACEAN GREEN ALGAE (CHLOROPHYTA) 1
TLDR
Two species of the colonial green flagellate family Volvocaceae are worldwide in distribution yet exhibit contrasting species structure, and it is inferred that either P. morum is a more ancient species than G. pectorale or that P.morum has a less stable genome, which may reflect climatological changes of the past.
BIOGEOGRAPHY OF CLADOPHOROPSIS MEMBRANACEA (CHLOROPHYTA) BASED ON COMPARISONS OF NUCLEAR rDNA ITS SEQUENCES 1
TLDR
The results demonstrate the usefulness of ITS sequences at the sub‐specific level in C. membranacea and support for the hypothesis that dispersal has occurred between the Caribbean and the tropical eastern Atlantic.
EVOLUTION OF MACROCYSTIS SPP. (PHAEOPHYCEAE) AS DETERMINED BY ITS1 AND ITS2 SEQUENCES1,
TLDR
Macrocystis may be a monospecific genus (M. pyrifera), and a northern‐hemisphere‐to‐southern-hemisphere pattern of dispersal was inferred, because northern•hemisphere individuals were more diverse and displayed paraphyletic clades, whereas southern‐hem hemisphere individuals were less diverse and formed a monophyleticClade.
Seasonality and thallus ontogeny of edible seaweed Monostroma latissimum (Kützing) Wittrock (Chlorophyta, Monostromataceae) from Tosa Bay, Kochi, Japan
TLDR
Seasonal fluctuations in thallus length were found to be distinctive to the habitat where the strain grows and re-occur annually and it is likely that salinity influences the maturation of microscopic sporophytes or the growth and survival of germlings in M. latissimum.
SOLVING TAXONOMIC AND NOMENCLATURAL PROBLEMS IN PACIFIC GIGARTINACEAE (RHODOPHYTA) USING DNA FROM TYPE MATERIAL
Molecular data obtained by a procedure for extracting PCR‐amplifiable nuclear and chloroplast DNA from old and formalin‐fixed red algal herbarium specimens were used to elucidate problems in the
DNA SEQUENCE VARIATION IN THE RIBOSOMAL INTERNAL TRANSCRIBED SPACER REGION OF FRESHWATER CLADOPHORA SPECIES (CHLOROPHYTA) 1
TLDR
Nucleotide sequences of the internal transcribed spacer (ITS) region of the nuclear ribosomal cistron of freshwater Cladophora species from a wide range of habitats and geographic locations are determined.
PHYLOGENETIC POSITION OF BOLBOCOLEON PILIFERUM (ULVOPHYCEAE, CHLOROPHYTA): EVIDENCE FROM REPRODUCTION, ZOOSPORE AND GAMETE ULTRASTRUCTURE, AND SMALL SUBUNIT RRNA GENE SEQUENCES 1
TLDR
Molecular phylogenetic analyses placed B. piliferum within the Ulvophyceae, at the base of a clade that contains representatives of the families Ulvaceae, Ulvellaceae, and Kornmanniaceae, which support an earlier hypothesis that B. Piliferum constitutes a distinct lineage.
MOLECULAR AND MORPHOLOGICAL ANALYSIS OF ENTEROMORPHA INTESTINALIS AND E. COMPRESSA (CHLOROPHYTA) IN THE BRITISH ISLES
The very common green seaweeds Enteromorpha intestinalis (L.) Nees and E. compressa (L.) Nees are important fouling organisms and have commonly been used as indicators of eutrophication, but their
Linnaeus was right all along: Ulva and Enteromorpha are not distinct genera
TLDR
Preliminary results provide strong evidence that Ulva, Enteromorpha and Chloropelta are not distinct evolutionary entities and should not be recognized as separate genera.
