Phylogenetics and Systematics of the Millipede genus Brachycybe Wood, 1864 (Platydesmida: Andrognathidae)
(East Carolina University, 2010)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, ... -
Phylogeny and Classification of the Trapdoor Spider Genus : An Integrative Approach to Evaluating Taxonomic Hypotheses
(2010)Background Revised by Bond and Platnick in 2007, the trapdoor spider genus Myrmekiaphila comprises 11 species. Species delimitation and placement within one of three species groups was based on modifications of the male ... -
Physiological and Phylogenetic Studies of the Biogeography of Alkaliphilic Heterotrophic Bacteria from Serpentinizing Habitats
(East Carolina University, 2014)Serpentinization occurs when ultramafic rocks containing the mineral olivine react with water to produce highly reducing conditions, which are commonly coincident with high concentrations of hydrogen. Hydrogen provides ... -
Physiological Studies of Alkaliphilic Anaerobic Organotrophs in a Serpentinizing Subsurface Habitat
(East Carolina University, 2014)Microbial habitats in serpentinizing ultramafic rocks represent one of the largest, yet least understood portions of the biosphere, with potentially major consequences for global biogeochemical cycles. Serpentinization is ... -
Pleistocene glacial refugia across the Appalachian Mountains and coastal plain in the millipede genus Narceus: Evidence from population genetic, phylogeographic, and paleoclimatic data
(East Carolina University, 2009-01-30)Background: Species that are widespread throughout historically glaciated and currently nonglaciated areas provide excellent opportunities to investigate the role of Pleistocene climatic change on the distribution of North ... -
Poison frog warning signals: From the rainforest to the genome and back again
(East Carolina University, 2018-06-18)Signal communication is pervasive in nature and is used to convey information to both conspecifics and heterospecifics. Aposematic species use warning signals (e.g. bright coloration) to alert predators to the presence of ...
