Arthropod Phylogenetics in Light of Three Novel Millipede (Myriapoda: Diplopoda) Mitochondrial Genomes with Comments on the Appropriateness of Mitochondrial Genome Sequence Data for Inferring Deep Level Relationships
(2013)Background Arthropods are the most diverse group of eukaryotic organisms, but their phylogenetic relationships are poorly understood. Herein, we describe three mitochondrial genomes representing orders of millipedes for ... -
Evolution of Plant Nucleotide-Sugar Interconversion Enzymes
(2011)Nucleotide-diphospho-sugars (NDP-sugars) are the building blocks of diverse polysaccharides and glycoconjugates in all organisms. In plants, 11 families of NDP-sugar interconversion enzymes (NSEs) have been identified, ... -
Footprints in the sand: independent reduction of subdigital lamellae in the Namib–Kalahari burrowing geckos
(East Carolina University, 2006-04-07)Many desert organisms exhibit convergence, and certain physical factors such as windblown sands have generated remarkably similar ecomorphs across divergent lineages. The burrowing geckos Colopus, Chondrodactylus and ... -
HIGHER-LEVEL SYSTEMATICS OF THE MILLIPEDES (ARTHROPODA: MYRIAPODA: DIPLOPODA) EVALUATED USING TRANSCRIPTOMIC DATA, MITOCHONDRIAL GENOMICS, AND CLASSIFICATION ANALYSES
(East Carolina University, 2012)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 ... -
Lateral Gene Transfer between Bacteria and Trichoderma reesei
(East Carolina University, 2012)Lateral gene transfer (LGT) has played an important role in shaping the `tree of life'. It has promoted evolution by generating gene redundancies, which allow for more freedom in terms of allowed mutations in a genome, ... -
Millipede Taxonomy after 250 Years: Classification and Taxonomic Practices in a Mega-Diverse yet Understudied Arthropod Group
(2012)Background The arthropod class Diplopoda is a mega-diverse group comprising >12,000 described millipede species. The history of taxonomic research within the group is tumultuous and, consequently, has yielded a questionable ... -
PARSING POLYPHYLETIC PUERARIA : DELIMITING DISTINCT EVOLUTIONARY LINEAGES THROUGH PHYLOGENY
(East Carolina University, 2013)A taxon is defined as polyphyletic when it does not include the last common ancestor of all true members of the taxon, resulting in a number of subgroups not united by a common ancestor. Previous work has suggested Pueraria ...
