Phylogenetic relationships and limb loss in sub-Saharan African scincine lizards (Squamata: Scincidae).
TLDR
Reconstructions of ancestral states for limb and digital characters show limited support for the reversal or gain of both digits and limbs, but conservative interpretation of the results suggest that limb loss is common, occurring multiple times throughout evolutionary history, and is most likely not reversible.

A molecular phylogeny of fleas (Insecta: Siphonaptera): origins and host associations
TLDR
This analysis supports Tungidae as the most basal flea lineage, sister group to the remainder of the extant fleas, and the first formal analysis of flea relationships based on a molecular matrix of four loci for 128 flea taxa from around the world. Expand
Comparing alignment methods for inferring the history of the new world lizard genus Mabuya (Squamata: Scincidae).
TLDR
This paper uses a diverse sampling of gene regions from lizards of the genus Mabuya to compare the impact of new maximum likelihood alignment algorithms with more widely used methods, and shows that the consistent use of model-based methods in both alignment and tree reconstruction leads to trees with more optimal likelihood scores.

Biogeographic regionalization of Australia: assigning conservation priorities based on endemic freshwater crayfish phylogenetics
TLDR
Using a phylogeny of 35 representative crayfish based on 16 S rDNA sequence data, both methods agreed that the north-west coast of Tasmania and the south-eastern portion of the continent were of highest priority for conserving the greatest amount of diversity. Expand
Molecular phylogenetics of Malagasy skinks (Squamata: Scincidae)
TLDR
A phylogeny of Malagasy “scincine” lizards is presented, based on quantitative phylogenetic analysis of data from seven molecular markers, which confirms the paraphyly of "Amphiglossus”, and supports Madascincus as a valid genus. Expand
A revision of the East African species of Melanoseps Boulenger (Sauria: Scincidae: Feylininae)
TLDR
Sequence data analysed from three mitochondrial genes strongly supports the monophyly of the East African Melanoseps relative to M. occidentalis and appears polyphyletic and requires further genetic investigation. Expand
Is Wing Recurrence really impossible?: a reply to Trueman et al.
By using multiple molecular markers and employing several methods of tree reconstruction and character optimization, we demonstrated that the ancestral phasmid is reconstructed unambiguously asExpand
Phylogenetic Systematics and Evolution within the Family Scincidae
TLDR
This dissertation is to use multiple mitochonidrial and nuclear DNA markers in connection with current cladistic methods to address evolutionary questions at many levels within Scincidae to show that Direct Optimization consistently finds more optimal tree topologies regardless of the optimality criterion used.
