Striped Bass Egg Abundance Viability in Scotland Neck, Roanoke River, North Carolina, for 1991
(East Carolina University, 1992-10)From 15 April to 14 June 1991, annual production and viability estimates of striped bass, Morone saxarilis, eggs spawned in the Roanoke River, North Carolina, were determined by sampling downstream of the spawning grounds ... -
Determining the Relationship Between Water Quality and Ulcerative Mycosis in Atlantic Menhaden
(East Carolina University, 1993-03)The objectives of this study were to investigate the possible causes of ulcerative mycosis (UM) in the Albemarle-Pamlico Estuary. Ulcerative mycosis is the commonest disease affecting the finfish populations of the ... -
Abundance and Viability of Striped Bass Eggs Spawned in the Roanoke River, North Carolina in 1991
(East Carolina University, 1993-05)Striped bass spawning activity in the Roanoke River, North Carolina, was documented in 1991 by sampling for eggs at Barnhill’s Landing (River Mile 117), which is just downstream of the spawning grounds between the towns ... -
Enzymatic determination of itoic acid, a Bacillus subtilis siderophore, and 2,3-dihydroxybenzoic acid.
(East Carolina University, 1993-07)A specific enzymatic method to determine the amounts of itoic acid, a Bacillus subtilis siderophore, and 2,3-dihydroxybenzoic acid (2,3-DHBA) was devised. A sample was incubated first with hippurate hydrolase andthenwith ... -
Benthic Biocriteria Assessment of the Lower Roanoke River, North Carolina: A Final Report to Weyerhaeuser Paper Company
(East Carolina University, 1993-10)Recent changes in environmental monitoring procedures of industrial activities suggest that future environmental assessments will be made using biocriteria methodology. Benthic macroinvertebrates have been the most often ... -
Roanoke River Water Flow Committee Report for 1991-1993
(East Carolina University, 1993-11)A Committee of representatives from State and Federal agencies and State universities was formed in 1988 to gather information on natural resources of the lower Roanoke River watershed in North Carolina and to recommend a ... -
Skimmer Trawl Modifications to Reduce Bycatch in the Inshore Brown and Pink Shrimp Fishery in North Carolina
(East Carolina University, 1995-06)A study was conducted during May-June 1995 comparing catch composition of a standard high profile skimmer trawl net (12 fi) and a low profile skimmer trawl net (3 fi) in the North and Newport Rivers, North Carolina. Each ... -
Striped Bass Egg Abundance and Viability in the Roanoke River, North Carolina, and Young-of-Year Survivorship, for 1993
(East Carolina University, 1995-10)Striped bass spawning activity in the Roanoke River, North Carolina, was documented in 1993 by sampling for eggs at Barnhill's Landing (River Mile 117), which is just downstream of the spawning grounds between the towns ... -
Method of treating anxiety-related disorders with 2-aminocycloaliphatic amide compounds
(1995-12-12)A method for combatting anxiety in a subject in need of such treatment is provided. The method comprises administering to the subject a 2-aminocycloaliphatic amide kappa opioid agonist in an effective anxiety-combatting amount. -
Life History Aspects of the Hickory Shad (Alosa Mediocris) in the Albemarle Sound/ Roanoke River Watershed, North Carolina
(East Carolina University, 1998-01)The hickory shad (Alosa mediocris), which supports commercial and recreational fisheries in the Roanoke River and Albemarle Sound, North Carolina, is an anadromous species closely related to the American shad (A. sapidissima). ... -
Identification and mapping of two divergent, unlinked major histocompatibility complex class II B genes in Xiphophorus fishes.
(East Carolina University, 1998-08)We have isolated two major histocompatibility complex (MHC) class II B genes from the inbred fish strain Xiphophorus maculatus Jp 163 A. We mapped one of these genes, designated here as DXB, to linkage group III, linked ... -
Characterization of critical spawning habitats of weakfish, spotted seatrout and red drum in Pamlico Sound using hydrophone surveys
(1999)Final report for "Characterization of critical spawning habitats of weakfish, spotted seatrout and red drum in Pamlico Sound using hydrophone surveys." -
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 ... -
Comparison of the exoS Gene and Protein Expression in Soil and Clinical Isolates of Pseudomonas aeruginosa
(East Carolina University, 2001-04)Exoenzyme S (ExoS) is translocated into eukaryotic cells by the type III secretory process and has been hypothesized to function in conjunction with other virulence factors in the pathogenesis of Pseudomonas aeruginosa. ... -
Ancient Genome Duplications Did Not Structure the Human Hox-Bearing Chromosomes
(East Carolina University, 2001-05)The fact that there are four homeobox (Hox) clusters in most vertebrates but only one in invertebrates is often cited as evidence for the hypothesis that two rounds of genome duplication by polyploidization occurred early ... -
The evolution of coloration and toxicity in the poison frog family (Dendrobatidae)
(East Carolina University, 2001-05-22)The poison frogs (family Dendrobatidae) are terrestrial anuran amphibians displaying a wide range of coloration and toxicity. These frogs generally have been considered to be aposematic, but relatively little ... -
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 ... -
Molecular phylogenetic evidence for a mimetic radiation in Peruvian poison frogs supports a Müllerian mimicry hypothesis.
(East Carolina University, 2001-12-07)Examples of Müllerian mimicry, in which resemblance between unpalatable species confers mutual benefit, are rare in vertebrates. Strong comparative evidence for mimicry is found when the colour and pattern of a single ... -
Evolution of the RNA polymerase II C-terminal domain
(East Carolina University, 2002-04-30)In recent years a great deal of biochemical and genetic research has focused on the C-terminal domain (CTD) of the largest subunit (RPB1) of DNA-dependent RNA polymerase II. This strongly conserved domain of tandemly ... -
