1. Spruill, Chad Lee. Phylogenetics and Systematics of the Millipede genus Brachycybe Wood 1864 (Platydesmida: Andrognathidae).

Degree: 2010, East Carolina University

The genus Brachycybe Wood 1864 (Platydesmida: Andrognathidae) belongs to an ancient millipede lineage that has persisted since the Miocene. The group displays a Holarctic distribution with species in the eastern Nearctic western Nearctic and eastern Palaearctic. Like many millipede groups its taxonomy to date has been based solely on morphology which may under represent species richness by ignoring cryptic species. Here we present the first phylogenetic analyses for Brachycybe based on molecular data obtained from the mitochondrial genes cytochrome c oxidase 1 and cytochrome b. Standard phylogenetic methods were used to reconstruct the evolutionary relationships of the group. Using the internal phylogenetic framework we evaluated geographic associations among clades; species boundaries were evaluated using the cohesion species concept. The application of molecular phylogenetics phylogeographic methods and the cohesion species concept to the genus Brachycybe is used to evaluate its species diversity. The mitochondrial genome of Brachycybe lecontii Wood 1864 (Platydesmida: Andrognathidae) is also presented here along with the phylogeny of Myriapoda produced using the amino acid sequences from the entire mitochondrial genome. The complete mitochondrial genome sequence of Brachycybe lecontii comprises 15 465 base pairs and includes 13 protein-encoding genes 21 tRNA genes two rRNA genes and two large non coding regions that are approximately 436 and 464 bp in length. The genome is uncharacteristic of typical Diplopods and varies dramatically from other sequenced members of the Arthropoda. The unique gene synteny is novel among others because of the rearrangement of two protein coding genes (nad1 and nad5) along with their retained transcriptional polarity. The phylogeny produced from these data recover the monophyly of the Myriapoda classes. However support values within the Diplopoda are low possibly due to the inclusion of atp8 in the analysis. This will have important implications for taxonomic research because it will expand the growing bank of complete millipede mitochondrial genomes allow more robust phylogenetic analyses and aid in the development of more genetic markers and consequently larger nucleotide datasets. ; Biology, Molecular biology, Systematic biology Advisors/Committee Members: Jason E.

2. Brewer, Michael Scott. HIGHER-LEVEL SYSTEMATICS OF THE MILLIPEDES (ARTHROPODA: MYRIAPODA: DIPLOPODA) EVALUATED USING TRANSCRIPTOMIC DATA MITOCHONDRIAL GENOMICS AND CLASSIFICATION ANALYSES.

Degree: 2012, East Carolina University

Knowledge of deep level phylogenetic relationships within and between many animal groups is currently lacking. Past attempts to reconstruct these ancient evolutionary relationships once relied chiefly on morphological characters and consequently suffered from deficiencies inherent to these data (homoplasy few diagnostic characters etc.). Advances in molecular biology over the last 20 years (namely PCR and high-throughput sequencing) have provided a whole other facet of potential characters via a vast array of loci both nuclear and mitochondrial which represent unlinked regions spanning entire genomes. The class Diplopoda (the millipedes) is a diverse group 12 000 described species which has suffered a long and convoluted taxonomic and systematic history. Containing many overinflated groups (numerous monotypic taxa) while other groups are vastly understudied the current scheme of classification does not reflect the evolutionary history of the group but instead exists primarily for identification purposes. A classification constructed in such a manner can be characterized as an "unnatural classification". This work represents an attempt to: 1) ascertain the uniformity of millipede taxa at the ordinal level by evaluating species diversity contained in higher taxa (orders families genera); 2) achieve a robust and empirically derived estimate of millipede global diversity; 3) reconstruct the higher level relationships among all major millipede taxa using genomic scale molecular data; 4) map the ancestral states of key millipede characteristics; and 5) date the divergences of major diplopod lineages. Full mitochondrial genomes and transcriptomic data obtained via second-generation sequencing for exemplar taxa representing the ordinal taxa were used to reconstruct the relationships between the higher millipede taxa. Our work uncovered interesting and potentially alarming trends in millipede taxonomy. Additionally we demonstrated the utility or lack thereof of using mitochondrial sequence data to reconstruct deep evolutionary relationships. Transcriptomic data analyses yielded well- supported trees containing relationships that have not been suggested previously. The transcriptome-based phylogeny was used to reconstruct the evolutionary changes of key millipede characteristics and consequently to assess their utility in delineating millipede taxa. This information provides a basis for future work within the Diplopoda including but not limited to: character evolution biogeography divergence time estimations and comparative genomics. ; Systematic biology, Entomology, Genetics, Diplopoda, Genomics, Mitochondria, Next-generation sequencing, Phylogenetics, Transcriptome Advisors/Committee Members: Jason E.
