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 ... -
“What if all those people came together?”: Fostering Children’s Self-Efficacy for Environmental Action, Interest, and Content Knowledge Through Participation in a Water Quality Citizen Science Project
(East Carolina University, 2023-04-13)Citizen science is the involvement of the public in scientific research through collaboration with scientists. These projects create ways for the public to be exposed to new information, spark new interests, and change ... -
Widespread impact of horizontal gene transfer on plant colonization of land
(2012-10)In complex multicellular eukaryotes such as animals and plants, horizontal gene transfer is commonly considered rare with very limited evolutionary significance. Here we show that horizontal gene transfer is a dynamic ...
