Relaxed phylogenetics and dating with confidence 2016

A single endemic and three exotic species of the termite genus Coptotermes (Isoptera, Rhinotermitidae) in the New World. M., Seifert, B., Stauffer, C., Christian, E., and Crozier, R. Our approach also provides a means for measuring the clocklikeness of datasets and comparing this measure between different genes and phylogenies.We find no significant rate autocorrelation among branches in three large datasets, suggesting that autocorrelated models are not necessarily suitable for these data. Further examination of cuticular hydrocarbons of worker termites of Australian Coptotermes (Isoptera : Rhinotermitidae) reveals greater taxonomic complexity within species. A mitochondrial genome phylogeny of termites (Blattodea : Termitoidae): robust support for interfamilial relationships and molecular synapomorphies define major clades. | Chouvenc, T., Li, H.-F., Austin, J., Bordereau, C., Bourguignon, T., Cameron, S. Despite their dominance in phylogenetic inference, it is evident that both are biologically unrealistic and that the real evolutionary process lies between these two extremes.Fortunately, intermediate models employing relaxed molecular clocks have been described.

The benchmarks for determining the mutation rate are often fossil or archaeological dates.

Revisiting Coptotermes (Isoptera : Rhinotermitidae): a global taxonomic road map for species validity and distribution of an economically important subterranean termite genus.

Endemic to South America, octodontid rodents are remarkable by being the only mammal taxa where allotetraploidy has been documented.

The taxon’s extensive morpho-physiological radiation associated to niche shifts has allowed testing phylogeographic hypotheses.
