Understanding the nature, timing and geographic context of historical events and population processes that shaped the spatial distribution of genetic diversity is critical for addressing questions relating to speciation, selection, and applied conservation management. Cladistic analysis of gene trees has been central to phylogeography, but when coupled with approaches that make use of different...

Genomic retrotransposons are major genomic components in most eukaryotic organisms. Their abundance in the genome is generally correlated with genome size. These elements spread throughout the genome by a process termed retro-transposition consisting of transcription, reverse transcription and reinsertion of the copied element into a new genomic location. The target sites are relatively unspeci...

This thesis is about phylogenetic trees mathematical graph structures which represent the pattern of evolution. More speci cally, it is concerned primarily with cladograms, the simplest type of phylogenetic tree, and the information they provide about the branching pattern of evolution. Although theoretical in orientation a real dataset is analysed in some detail and a user-friendly program pro...

The use of distance data in phylogenetic inference retains adherents in molecular systematics, despite the well-established cladistic critique of distances. Molecular distance matrices have been supposed to measure evolutionary divergence; however, trees based upon analyses of such matrices are generally uninterpretable as doing so-under realistic conditions (Farris, 1981, 1985, 1986). In addit...

An overview of the controversial proposal for the major eukaryote taxon "Excavata" is presented. Excavata is predicted to include at least ten distinct groups: jakobids, Malawimonas, Trimastix, Carpediemonas, retortamonads, diplomonads, Heterolobosea, oxymonads, parabasalids and Euglenozoa. These "excavates" have broadly similar flagellar apparatus organizations, for which a "universal" termino...

The taxonomic placement of an enigmatic species of wasp known from two specimens in Late Cretaceous New Jersey amber is investigated through cladistic analyses of 90 morphological characters for 33 terminals ranging across non-Aculeata, non-Chrysidoidea, most subfamilies of Chrysidoidea and all genera of Plumariidae (the family to which the fossils were initially assigned), based on use of exem...
