A mitogenomic phylogeny of chitons (Mollusca: Polyplacophora)

open access: yesBMC Evolutionary Biology, 2020
Background Polyplacophora, or chitons, have long fascinated malacologists for their distinct and rather conserved morphology and lifestyle compared to other mollusk classes.

New insights into the phylogeny and relationships within the worldwide genus Riccardia (Aneuraceae, Marchantiophytina)

open access: yesEuropean Journal of Taxonomy, 2017
With 280 accepted species, the genus Riccardia S.F.Gray (Aneuraceae) is one of the most speciose genera of simple thalloid liverworts. The current classification of this genus is based on morphological and limited-sampling molecular studies.

Molecular phylogeny of kinorhynchs

open access: yesMolecular Phylogenetics and Evolution, 2013
We reconstructed kinorhynch phylogeny using maximum-likelihood and Bayesian analyses of nuclear 18S and 28S rRNA gene sequences from 30 species in 13 genera (18S) and 23 species in 12 genera (28S), representing eight families and both orders (Cyclorhagida and Homalorhagida) currently recognized in the phylum. We analyzed the two genes individually (18S

Crinoid phylogeny: a preliminary analysis (Echinodermata: Crinoidea) [PDF]

open access: yes, 2004
We describe the first molecular and morphological analysis of extant crinoid high-level inter-relationships. Nuclear and mitochondrial gene sequences and a cladistically coded matrix of 30 morphological characters are presented, and analysed by ...

Time-calibrated molecular phylogeny of pteropods.

open access: yesPLoS ONE, 2017
Pteropods are a widespread group of holoplanktonic gastropod molluscs and are uniquely suitable for study of long-term evolutionary processes in the open ocean because they are the only living metazoan plankton with a good fossil record.

Integration of Bayesian molecular clock methods and fossil-based soft bounds reveals early Cenozoic origin of African lacertid lizards [PDF]

open access: yes, 2009
Background Although current molecular clock methods offer greater flexibility in modelling historical evolutionary events, calibration of the clock with dates from the fossil record is still problematic for many groups.

Monophyly of brachiopods and phoronids: reconciliation of molecular evidence with Linnaean classification (the subphylum Phoroniformea nov.) [PDF]

open access: yes, 2000
Molecular phylogenetic analyses of aligned 18S rDNA gene sequences from articulate and inarticulate brachiopods representing all major extant lineages, an enhanced set of phoronids and several unrelated protostome taxa, confirm previous indications that ...

Phylogenetic review of the millipede genus Cherokia Chamberlin, 1949 (Polydesmida, Xystodesmidae) [PDF]

open access: yesZooKeys, 2022
The millipede genus Cherokia Chamberlin, 1949 is a monospecific taxon, with the type species Cherokia georgiana (Bollman, 1889). The last revision of the genus was made by Hoffman (1960) where he established three subspecies.

Dasylirion systematics: taxonomy and molecular phylogeny

open access: yesBotan‪ical Sciences, 1995
The results of a systematics study in which Dasylirion was fully monographed are reported. Sixteen species, including four new ones, were recognized. Data from chloroplast DNA restriction site analysis suggest that the species of Dasylirion in southern ...
