Disentangling ribbon worm relationships: multi‐locus analysis supports traditional classification of the phylum Nemertea
The phylogenetic relationships of selected members of the phylum Nemertea are explored by means of six markers amplified from the genomic DNA of freshly collected specimens, acting as a scaffold to which one could pinpoint any previously published study.
Mutation and Selection Cause Codon Usage and Bias in Mitochondrial Genomes of Ribbon Worms (Nemertea)
It is proposed that codons containing A or U at third position are used preferentially in nemertean species, regardless of whether corresponding tRNAs are encoded in the mitochondrial DNA.
Statistical Parsimony Networks and Species Assemblages in Cephalotrichid Nemerteans (Nemertea)
Statistical parsimony network analysis provides a rapid and useful tool for detecting possible undescribed/cryptic species among cephalotrichid nemerteans based on COI gene and should be combined with phylogenetic analysis to get indications of false positive results.
Differences in growth, total lipid content and fatty acid composition among 60 clones of Cylindrotheca fusiformis
The results support the view that some microalgal fatty acid variation is not restricted to interspecific variation and external factors, but also varies from clone to clone within the same species.
Taxonomic Identity of a Tetrodotoxin-Accumulating Ribbon-worm Cephalothrix simula (Nemertea: Palaeonemertea): A Species Artificially Introduced from the Pacific to Europe
Analysis of COI sequence showed that the Hiroshima population can be identified as C. simula, which has been found in previous studies from Trieste, Italy, and also from both the Mediterranean and Atlantic coasts of the Iberian Peninsula, indicating an artificial introduction via ballast water, ship-fouling communities, or the commercially cultured oyster Crassostrea gigas brought from Japan to France in 1970s.
Species Diversity of Ramphogordius sanguineus/Lineus ruber-Like Nemerteans (Nemertea: Heteronemertea) and Geographic Distribution of R. sanguineus
A DNA-based species delimitation/identification by means of statistical parsimony and phylogenetic analyses shows that the analyzed specimens may contain nine species, which can be separated by large genetic gaps; heteronemerteans with an external appearance similar to R. sanguineus/Lineus ruber/L.
The mitochondrial genomes of two nemerteans, Cephalothrix sp. (Nemertea: Palaeonemertea) and Paranemertes cf. peregrina (Nemertea: Hoplonemertea)
The mitochondrial genome sequences were determined for two species of nemerteans, Cephalothrix sp. (15,800 bp sequenced, near-complete) and Paranemertes cf. peregrina (14,558 bp, complete). As seen
The impact of one-decade ecological disturbance on genetic changes: a study on the brine shrimp Artemia urmiana from Urmia Lake, Iran
It is evident that a short-term ecological disturbance has impacted the genetic diversity and structure of A. urmiana in Urmia Lake, based on one cyst collections in 1994 and 2004.
Nemertean taxonomy—Implementing changes in the higher ranks, dismissing Anopla and Enopla
The ranks Anopla and Enopla are eliminated and the following system of the Nemertea phylum is implemented and genus Hubrechtella is transferred from class Palaeonemertea to the class Pilidiophora.
