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 ...
Nutrient contributions from septic systems in nutrient-sensitive watersheds: Quantifying nutrient inputs, reduction methods, and economic feasibility
(East Carolina University, 2019-04-30)
Eutrophication of surface waters is a global issue threatening aquatic ecosystems and recreational opportunities. Nutrient management strategies exist to reduce nutrient inputs from various sources; however, septic systems ...
Determining the role of the steroid hormone ecdysone in critical stages of Drosophila melanogaster early oogenesis
(East Carolina University, 2019-11-27)
Reproductive function in many organisms, including Drosophila melanogaster, is controlled by steroid hormones. The main steroid hormone in Drosophila is ecdysone, which is structurally and functionally similar to estrogen. ...
Listening to Ocean Life
(2019-05-30)
By using a remotely controlled autonomous vehicle ("Blackbeard" the Acoustic Wave Glider), the authors made recordings of sounds produced by striped cusk eels, sea robins, oyster toadfish, weakfish, red drum, spotted ...
MONITORING FISH SPAWNING LOCATIONS AND MARINE MAMMAL SOUNDS WITH PASSIVE ACOUSTIC RECORDER ON A WAVE GLIDER
(2019-07-08)
Remote observations of marine animal behavior have one distinct advantage over direct observations: the observer is not present to disturb the animals. There are no vessel noises, no diver’s bubbles, no people present that ...
Fine-mapping a novel locus on Chromosome 1 for associations with recurrent stroke
(East Carolina University, 2019-07-18)
INTRODUCTION: Stroke is a complex, multifactorial cerebrovascular disease that afflicts millions of individuals both nationally and globally. Of the annual 795,000 stroke incidents, approximately 185,000 are recurrent ...
Investigating the role of transcription factor, Trl, during germline development in the Drosophila ovary
(East Carolina University, 2019-07-22)
Oogenesis is the process by which an egg develops from undifferentiated cells in the ovary. The Drosophila melanogaster ovary is an assembly line for egg production, making it a great system to investigate initial oocyte ...
The effects of stress on avian gene expression and microbiomes
(East Carolina University, 2019-07-24)
Organisms must cope with stressors throughout their lifetime. Stressors are broad and come from both intrinsic and extrinsic sources. In this era of rapid global change, exposure to stressors will become more unpredictable ...
FUNCTIONS OF G-PROTEIN COUPLED ESTROGEN RECEPTOR (GPER) IN FEMALE ZEBRAFISH REPRODUCTION
(East Carolina University, 2019-11-27)
Abstract
Steroid hormones such as estrogen depend on receptors like Estrogen Receptor alpha (ERα) and Estrogen Receptor (ERβ) to mediate their slow “genomic” functions, and G-Protein coupled Estrogen Receptor (GPER) to ...
