Species delimitation and phylogeny of a New Zealand plant species radiation (2009)
Meudt, Heidi M, Lockhart, Peter J, Bryant, David
Abstract Background Delimiting species boundaries and reconstructing the evolutionary relationships of late Tertiary and Quaternary species radiations is difficult. One recent approach emphasizes the...
Using supernetworks to distinguish hybridization from lineage-sorting (2008)
Holland, Barbara R, Benthin, Steffi, Lockhart, Peter J, Moulton, Vincent, Huber, Katharina T
Abstract Background A simple and widely used approach for detecting hybridization in phylogenies is to reconstruct gene trees from independent gene loci, and to look for gene tree incongruence....
Kneip, Christoph, Voβ, Christine, Lockhart, Peter J, Maier, Uwe G
Abstract Background Bacteria occur in facultative association and intracellular symbiosis with a diversity of eukaryotic hosts. Recently, we have helped to characterise an intracellular nitrogen...

Gruenheit, Nicole, Lockhart, Peter J., Steel, Mike, Martin, William
The covarion (COV)-like properties of sequences are poorly described and their impact on phylogenetic analyses poorly understood. We demonstrate using simulations that, under an evolutionary model...

Abstract.—Phylogenetic inference is well known to be problematic if both long and short branches occur together in the underlying tree. With biological data, correcting for this problem may require...

A phylogenetic analysis of Nothofagus species provides evidence for their transoceanic dispersal during the Tertiary, and helps resolve the debate about the origins of plant biodiversity in the...

Nothofagus (southern beech), with an 80-million-year-old fossil record, has become iconic as a plant genus whose ancient Gondwanan relationships reach back into the Cretaceous era. Closely associated...

Biogeographic Interpretation of Splits Graphs: Least Squares Optimization of Branch Lengths (2005)
Winkworth, Richard C., Bryant, David, Lockhart, Peter J., Havell, David, Moulton, Vincent
Although most often used to represent phylogenetic uncertainty, network methods are also potentially useful for describing the phylogenetic complexity expected to characterize recent species...

A genome phylogeny for mitochondria among α-proteobacteria and a predominantly eubacterial ancestry of yeast nuclear genes
Using Consensus Networks to Visualize Contradictory Evidence for Species Phylogeny (2004)
Holland, Barbara R., Huber, Katharina T., Moulton, Vincent, Lockhart, Peter J.
Building species phylogenies from genome data requires the evaluation of phylogenetic evidence from independent gene loci. We propose an approach to do this using consensus networks. We compare gene...
