The ever-larger data matrices resulting from continuing improvements in DNA sequencing techniques require faster and more efficient methods of phylogenetic analysis. Here we explore a promising new ...

Null community is a spatio-temporal abstraction of an initial regional species pool from which local species pools and actual community assemblages are organized. Any process that causes joint ...

The rapid accumulation of genome sequence data has made phylogenetics an indispensable tool to various branches of biology. However, it has also posed considerable statistical and computational ...
