Patterns of septal biomineralization in Scleractinia compared with their 28S rRNA phylogeny: a dual approach for a new taxonomic framework
TLDR
The results suggest that co‐ordinated studies creating links between biomineralization patterns and molecular phylogeny may provide an efficient working approach for a re‐examination of scleractinian classification, and that patterns of septal microstructures are involved in the evolutionary scheme proposed by Wells.
Haplowebs as a graphical tool for delimiting species: a revival of Doyle's "field for recombination" approach and its application to the coral genus Pocillopora in Clipperton
TLDR
This work proposes to use haplowebs (haplotype networks with additional connections between haplotypes found co-occurring in heterozygous individuals) to visualize and delineate single-locus FFRs (sl-FFRs), and introduces a method to quantify the reliability of putative species boundaries according to the number of independent markers that support them.
Evolutionary relationships of euthyneuran gastropods (Mollusca): a cladistic re-evaluation of morphological characters
TLDR
Morphological characters of the Euthyneura available from the literature were re-evaluated in terms of terminology and primary homology and it appeared that the data matrix was highly homoplastic, and only robust nodes were retained in a concensus tree.
Mitochondrial sequences of Seriatopora corals show little agreement with morphology and reveal the duplication of a tRNA gene near the control region
The taxonomy of corals of the genus Seriatopora has not previously been studied using molecular sequence markers. As a first step toward a re-evaluation of species boundaries in this genus,
Phase determination from direct sequencing of length‐variable DNA regions
TLDR
It is found that phase could be reconstructed from direct sequencing of mixed PCR products by combining for each individual the complementary information contained in its forward and reverse chromatograms, provided these products had different lengths.
New clades of euthyneuran gastropods (Mollusca) from 28S rRNA sequences.
TLDR
Morphological characters which support the new clades obtained here are discussed and first molecular confirmation of monophylies of Hygrophila, including Chilina, Acteonoidea, and Sacoglossa, which include both shell-bearing species and slugs are discussed.
Phylogeny of the Megascolecidae and Crassiclitellata (Annelida, Oligochaeta): combined versus partitioned analysis using nuclear (28S) and mitochondrial (12S, 16S) rDNA
TLDR
La congruence et le soutien de pouvoir combine soutiennent nos conclusions : la plupart des groupements ont ete bases sur des homoplasies, par exemple l'origine multiple des prostates racemeuses et de the meronephridie de « type Dichogastrinae ».
