Fishers’ Perceptions of Ciguatoxin Fish Poisoning and Modeling Biomagnification of Ciguatoxin in the Trophic Dynamics of Caribbean Coral Reef Ecosystems
(East Carolina University, 2021-01-15)Ciguatoxin fish poisoning (CFP) is caused by the consumption of tropical and subtropical fishes and other marine species with high levels of ciguatoxin (CTX) in their tissues. CTX is a polycyclic neurotoxin produced by ... -
Fishing For The Evolutionary Bases Of Female Ornamentation
(East Carolina University, 2015)Sexual dimorphism, or phenotypic differentiation of the sexes, is widespread amongst animals. It is understood mainly in the context of sexual selection, i.e. selection on mating success, with such selection typically ... -
Folic acid elicits diverse effects over all major life stages and body systems
(East Carolina University, 2018-04-25)Over several decades, the vitamin supplement folic acid has been praised for its ability to reduce neural tube defects in the developing embryo. Many studies show that folic acid plays a vital role in the reduction of ... -
Food and feeding habits of the spiny dogfish Squalus acanthias overwintering off the coast of North Carolina and the effects on the marine community
(East Carolina University, 2012)Spiny dogfish (Squalus acanthias) are small, highly migratory sharks that occur in large numbers in North Carolina nearshore waters between November and March. This species has long been considered a pest by commercial ... -
Food and Feeding of Young Striped Bass in Roanoke River and Western Albemarle Sound, North Carolina, 1984-1991
(East Carolina University, 1992-07) -
Food and Feeding of Young Striped Bass in the Lower Roanoke River and Western Albemarle Sound, North Carolina, 1990-1991
(East Carolina University, 1992-07)This study was conducted during the springs of 1990 and 1991 to provide information on possible causes of the decline in the Roanoke/Albemarle striped bass stock. Striped bass in this system migrate approximately 130 miles ... -
Footprints in the sand: independent reduction of subdigital lamellae in the Namib–Kalahari burrowing geckos
(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 ... -
A Functional Analysis of microRNAs in Nicotiana tabacum
(East Carolina University, 2012)MicroRNAs (miRNAs) are a newly discovered class of endogenous post-transcriptional gene regulators that are typically 20-22 nucleotides in length that do not code for proteins. MiRNAs regulate gene expression by either ... -
Functional Unit of the RNA Polymerase II C-Terminal Domain Lies within Heptapeptide PairsÂ
(East Carolina University, 2004-06)Unlike all other RNA polymerases, the largest subunit (RPB1) of eukaryotic DNA-dependent RNA polymerase II (RNAP II) has a C-terminal domain (CTD) comprising tandemly repeated heptapeptides with the consensus sequence ... -
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 ... -
The Fur-like regulator Mur controls the expression of the gene encoding the manganese transporter MntH in Brucella abortus 2308 in response to manganese availability
(East Carolina University, 2011)Brucella abortus is a Gram-negative, [alpha]-proteobacterium that causes bovine brucellosis, a prevalent zoonotic disease in many areas of the world. Brucella abortus is an intracellular pathogen that survives and ...
