Seasonal home range dynamics and sex differences in habitat use in a threatened, coastal marsh bird
(2016-12-22)A comprehensive understanding of spatiotemporal ecology is needed to develop conservation strategies for declining species. The king rail (Rallus elegans) is a secretive marsh bird whose range historically extended across ... -
A second locality for the Namib darkling beetle Onymacris brainei (Tenebrionidae, Coleoptera) and first report on its molecular phylogenetic placement
(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 ... -

(2017)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 ... -
Selection of Reliable Reference Genes in for Analysis of Nanotoxicity
(2012)Despite rapid development and application of a wide range of manufactured metal oxide nanoparticles (NPs), the understanding of potential risks of using NPs is less completed, especially at the molecular level. The nematode ... -
SEQUENCING AND COMPARATIVE ANALYSIS OF THE MITOCHONDRIAL CYTOCHROME B GENE IN THE MARION UPLANDS FLORIDA SAND SKINK (PLESTIODON REYNOLDSI)
(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 ... -
Sexual Dimorphism and Trophic Trait Evolution in the Carolina Bay Fundulus Complex
(East Carolina University, 2017-01-05)Convergent evolution in similar environments is widely held to provide some of the strongest evidence for natural selection's role in evolution, and convergent or parallel evolution of reproductive isolation, best studied ... -
Simultaneous Positive and Purifying Selection on Overlapping Reading Frames of the tat and vpr Genes of Simian Immunodeficiency Virus
(East Carolina University, 2001-09)Tat-specific cytotoxic T cells have previously been shown to exert positive Darwinian selection favoring amino acid replacements of an epitope of simian immunodeficiency virus (SIV). The region of the tat gene encoding ...
