An assessment of the polytypic status of the Namib darkling beetles Onymacris unguicularis and Onymacris rugatipennis
Pollard, Rachel M. (2014)The southern African beetle genus Onymacris (family Tenebrionidae) comprises 14 species, six of which are polytypic. Despite longstanding research on the physiological and behavioral adaptations of these desert beetles, ... -

Digits Lost or Gained? Evidence for Pedal Evolution in the Dwarf Salamander Complex ( Plethodontidae)
Lamb, Trip; Beamer, David A. (2012)Change in digit number, particularly digit loss, has occurred repeatedly over the evolutionary history of tetrapods. Although digit loss has been documented among distantly related species of salamanders, it is relatively ... -
Footprints in the sand: independent reduction of subdigital lamellae in the Namib–Kalahari burrowing geckos
Lamb, Trip; Bauer, Aaron M. (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 ... -
Genetic variation corroborates subspecific delimitation in the Namib fog-basking beetle, (Haag) (Tenebrionidae, Coleoptera)
Lamb, Trip; Pollard, Rachel; Bond, Jason E. (2013)The fog-basking beetle, Onymacris unguicularis (Haag, 1875), is currently listed as a polytypic form comprising two subspecies. A flightless substrate specialist, the beetleis endemic to vegetationless dunes in the Namib, ... -
MITOCHONDRIAL DNA VARIATION IN THE PITCHER PLANT FLY SARCOPHAGA SARRACENIAE: EXPLORING POSSIBLE INFLUENCES OF HOST SPECIFICITY AND GEOGRAPHIC STRUCTURING
Parker, Joshua David (East Carolina University, 2019-05-03)North American pitcher plants (Sarracenia) are a recently evolved (~3 my) assemblage of 11 carnivorous species. Sarracenia pitchers also provide resources (food, shelter) for certain arthropods, including two genera of ... -
Rectifying Limitations On Species Delineation In Dusky Salamanders : Lineage Detection Using An Ecoregion-Drainage Sampling Regime
Beamer, David A. (East Carolina University, 2015)The dusky salamanders (Desmognathus) constitute a large, species-rich group, and although a considerable body of literature exists on systematic relationships and adaptive trends, these issues have heretofore been approached ... -
A second locality for the Namib darkling beetle Onymacris brainei (Tenebrionidae, Coleoptera) and first report on its molecular phylogenetic placement
Lamb, Trip; Marais, Eugene; Bond, Jason E. (2017-08-01)Onymacris brainei Penrith, 1984 – the most recent species of Onymacris to be described – is known only from its type locality in the Namib Desert, adjacent to the Cunene River in northern Namibia. No additional specimens ... -

SEQUENCING AND COMPARATIVE ANALYSIS OF THE MITOCHONDRIAL CYTOCHROME B GENE IN THE MARION UPLANDS FLORIDA SAND SKINK (PLESTIODON REYNOLDSI)
Locklear, Taylor R. (East Carolina University, 2016-04-28)The Florida sand skink (Plestiodon reynoldsi)—a small (~10 cm) lizard endemic to the peninsula—is a ‘sand-swimming’ specialist restricted to Florida scrub habitat on the state’s central highland ridges. Florida scrub has ...
