Molecular estimation of eulipotyphlan divergence times and the evolution of “Insectivora”
Molecular Phylogenetics and Evolution, 2003"Insectivores" are one of the key groups in understanding mammalian origins. For years, systematics of "Lipotyphla" taxa remained extremely unstable and challenged. Today, with the application of molecular techniques, "Lipotyphla" appears to be a paraphyletic assemblage that encompasses hedgehogs, shrews, and moles (i.e., Eulipotyphla-a member of ...

Gene arrangement, phylogeny and divergence time estimation of mitogenomes in Thrips
Molecular Biology Reports, 2022The metazoan mitogenomes usually display conserved gene arrangement while thrips are known for their extensive gene rearrangement, and duplication of the control region.We sequenced complete mitogenomes of eight species of thrips to determine the gene arrangement, phylogeny and divergence time estimation.

Bayesian relaxed clock estimation of divergence times in foraminifera
Molecular Phylogenetics and Evolution, 2011Accurate and precise estimation of divergence times during the Neo-Proterozoic is necessary to understand the speciation dynamic of early Eukaryotes. However such deep divergences are difficult to date, as the molecular clock is seriously violated. Recent improvements in Bayesian molecular dating techniques allow the relaxation of the molecular clock ...

Estimation of the time of concentration for diverging surfaces
Hydrological Sciences Journal, 1988A solution is obtained for estimating the time of concentration for a diverging watershed. A comparison of concentration times for diverging and plane surfaces is made to examine the influence of the degree of divergence for a diverging watershed on the time of concentration.

Interval estimates of language divergence times
Journal of Applied Probability, 1970It is often convenient to construct a branching diagram to represent the relationships between languages belonging to the same language family (for example, between Romance languages such as Rumanian, Italian, French and Spanish). It is desirable that the diagram should illustrate both the closeness of the relationships (that is, which pairs of ...

Estimating divergence times among subfamilies in Nymphalidae
Science Bulletin, 2008The mitochondrial cytochrome oxidase subunit I (COI) gene and the nuclear elongation factor 1α (EF-1α) gene were sequenced from 13 species of Nymphalidae. Phylogenetic trees of Nymphalidae, which is the largest family in butterflies, were constructed based on the sequences determined from 13 species sequenced in our laboratory and an additional 43 ...

Divergence-time estimation in Indo-European
DiachronicaAbstract Divergence-time estimation is one of the most important endeavors in historical linguistics. Its importance is matched only by its difficulty. As Bayesian methods of divergence-time estimation have become more common over the past two decades, a number of critical issues have come to the ...

Molecular clock and estimation of species divergence times
2006Abstract This chapter focuses on statistical methods for testing the clock hypothesis, and on likelihood and Bayesian methods for dating species divergence events under global and local clock models. In such an analysis, fossils are used to calibrate the clock, that is, to translate sequence distances into absolute geological times and ...
