A validated protocol to quantify severity of male urogenital feminization using the MOUSE (Mouse objective urethral severity evaluation)
(2016-06-13)Background Congenital abnormalities vary in presentation, yet studies using model organisms tend to focus on occurrence rather than severity of the defect. Scoring severity of abnormalities in model systems allows explicit ... -
VALIDATION OF CANDIDATE GENES IN RESPONSE TO VERSICAN MANIPULATION IN DEVELOPING SYNOVIAL JOINTS
(East Carolina University, 2012)Little is understood about the complex process of synovial joint formation in early limb development. It has been shown that versican is highly expressed in the extracellular matrix of these joints (Snow et al., 2005; ... -
Variation in pigmentation gene expression is associated with distinct aposematic color morphs in the poison frog Dendrobates auratus
(2019-04-18)Abstract Background Color and pattern phenotypes have clear implications for survival and reproduction in many species. However, the mechanisms that produce this coloration ... -
Vectors of transmission: An early nicotine puff triggers a long-lasting microRNA molecular “memory” in C. elegans.
(East Carolina University, 2016-06-16)The prevalence of passive and active nicotine exposure among neonates, children and adolescents remains relatively high and varies among cultures and countries. Currently, there is ample evidence that a safe nicotine dose ... -
Venomics and Systematics of Robber Flies (Diptera: Asilidae)
(East Carolina University, 2021-04-23)Robber flies or assassin flies (Diptera: Asilidae) are a diverse family of venomous predators. The evolutionary history of this venom is poorly known. We leveraged venom transcriptomes from a diversity of robber flies and ... -
Versican Expression during Synovial Joint Morphogenesis
(East Carolina University, 2007-09)The extracellular matrix (ECM) plays a critical role in governing cell behavior and phenotype during limb skeletogenesis. Chondroitin sulfate proteoglycans (Cspgs) are highly expressed in the ECM of precartilage mesenchymal ... -
Visual mate choice in poison frogs.
(East Carolina University, 1999-11-07)We investigated female mate choice on the basis of visual cues in two populations of Dendrobates pumilio, the strawberry poison frog, from the Bocas del Toro Archipelago in Panama, Central America. Mate choice experiments ... -
VOCAL COMMUNICATION AND ACOUSTIC MONITORING OF THE KING RAIL (Rallus elegans)
(East Carolina University, 2018-05-02)Rare and elusive species present a challenge for researchers, and are consequently often overlooked in evolutionary and behavioral studies. The King Rail, Rallus elegans, is a secretive marsh bird considered globally ‘Near ... -
Wetland management strategies lead to tradeoffs in ecological structure and function
(2017-12)Anthropogenic legacy effects often occur as a consequence of land use change or land management and can leave behind long-lasting changes to ecosystem structure and function. This legacy is described as a memory in the ... -
What Factors Maintain the Mixed Mating System of a Local Annual Plant, Triodanis perfoliata?
(East Carolina University, 2019-05-02)A plant capable of reproducing by cross- and self-fertilization is known to have a mixed mating system. This system is an evolutionary puzzle to many researchers because the factors maintaining both outcrossing and selfing ...
