Sequence-based species delimitation for the DNA taxonomy of undescribed insects.
Cataloging the very large number of undescribed species of insects could be greatly accelerated by automated DNA based approaches, but procedures for large-scale species discovery from sequence data…
Revisiting the insect mitochondrial molecular clock: the mid-Aegean trench calibration.
A well-established biogeographic barrier is used, the mid-Aegean trench separating the western and eastern Aegean archipelago, to estimate substitution rates in tenebrionid beetles, and a divergence rate of 3.54% My(-1) for the cox1 gene was obtained under the preferred partitioning scheme and substitution model selected using Bayes factors.
Accelerated species inventory on Madagascar using coalescent-based models of species delineation.
A modified GMYC model is developed that allows for a variable transition from coalescent to speciation among lineages and provides a method of species discovery and biodiversity assessment using single-locus data from mixed or environmental samples while building a globally available taxonomic database for future identifications.
A Comprehensive Phylogeny of Beetles Reveals the Evolutionary Origins of a Superradiation
The phylogeny of Coleoptera found that the success of beetles is explained neither by exceptional net diversification rates nor by a predominant role of herbivory and the Cretaceous rise of angiosperms, suggesting that beetle species richness is due to high survival of lineages and sustained diversification in a variety of niches.
A comprehensive phylogenetic analysis of termites (Isoptera) illuminates key aspects of their evolutionary biology.
Detecting the Geographical Pattern of Speciation from Species‐Level Phylogenies
It is found that relatively recent speciation events are characterized by greater asymmetry in range size between sister clades than expected under the null models, providing potential support for the peripatric model of speciation.
A plea for DNA taxonomy
Sequence alignment of 18S ribosomal RNA and the basal relationships of Adephagan beetles: evidence for monophyly of aquatic families and the placement of Trachypachidae.
The analysis weakly supports monophyly of Adephaga, with Polyphaga usually as its sister, and the two small suborders Myxophaga and Archostemata basal to them, and a parametric bootstrapping test significantly rejects an hypothesis of nonmonophyly.
A molecular phylogenetic analysis of the Scarabaeinae (dung beetles).
The Effect of Geographical Scale of Sampling on DNA Barcoding
A CO1 data set of aquatic predaceous diving beetles of the tribe Agabini is presented and it is shown that even if samples are collected to maximize the geographical coverage, up to 70 individuals are required to sample 95% of intraspecific variation, showing that the geographical scale of sampling has a critical impact on the global application of DNA barcoding.
