Camaenid land snails on Barrow Island: distributions, molecular phylogenetics and taxonomic revision
The metric called phylogenetic diversity (PD) has been employed over the last 30 years to add an evolutionary dimension exploration of biodiversity. However, application PD was until recently limited by both technology and methodology. Newly available distributional data from global museum databasing efforts, rapidly increasing coverage DNA sequence improvements computer hardware software have ...
Caenorhabditis elegans is widely known as a model organism for cell, molecular, developmental and neural biology, but it is also being used for evolutionary studies. A recent meeting of researchers in Portugal covered topics as diverse as phylogenetics, genetic mapping of quantitative and qualitative intraspecific variation, evolutionary developmental biology and population genetics. Here, we s...
We present an alternative method for calculating likelihoods in molecular phylogenetics. Our method is based on partial likelihood tensors, which are generalizations of partial likelihood vectors, as used in Felsenstein's approach. Exploiting a lexicographic sorting and partial likelihood tensors, it is possible to obtain significant computational savings. We show this on a range of simulated d...
