Predator Out of Place : The Differential Impacts of Native and Non-native Crayfish on Bufo Tadpoles
(East Carolina University, 2010)
Predators have been shown to alter important fitness components (larval period, mass at metamorphosis, and overall survivorship) of larval anurans. Uncommonly studied predators of tadpoles include crayfish. Both native and ...
Drosophila Psf2 Has a Role In Chromosome Condensation
(East Carolina University, 2012)
The condensation state of chromosomes is a critical parameter in multiple processes within the cell. Failures in the maintenance of appropriate condensation states may lead to genomic instability, mis-expression of genes, ...
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 ...
Inbreeding Depression and Mixed Mating in Leptosiphon jepsonii: A Comparison of Three Populations
(East Carolina University, 2006-08)
Background and Aims: Inbreeding depression is thought to play a central role in the evolution and maintenance of cross-fertilization. Theory indicates that inbreeding depression can be purged with self-fertilization, ...
RDX Induces Aberrant Expression of MicroRNAs in Mouse Brain and Liver
(East Carolina University, 2009-02)
Background: Although microRNAs (miRNAs) have been found to play an important role in many biological and metabolic processes, their functions in animal response to environmental toxicant exposure are largely unknown. ...
Alteration of In Vivo Cellulose Ribbon Assembly by Carboxymethylcellulose and Other Polysaccharides
(East Carolina University, 1982)
In vivo cellulose ribbon assembly by the Gram-negative bacterium Acetobacter xylinum can be altered by incubation in carboxymethylcellulose (CMC), a negatively charged water-soluble cellulose derivative, and also by ...
Posttranslational modifications in the CP43 subunit of photosystem II
(East Carolina University, 2002-11-12)
Photosystem II (PSII) catalyzes the light-driven oxidation of water and the reduction of plastoquinone; the oxidation of water occurs at a cluster of four manganese. The PSII CP43 subunit functions in light ...
RDX and miRNA Expression: Zhang and Pan Respond
(East Carolina University, 2009-03)
Proserpinaca: Photoperiodic and Chemical Differentiation of Leaf Development and Flowering
(East Carolina University, 1967-05)
Proserpiniaca palustris L. produced juvenile leaves on 8-hour photoperiods, adult leaves on 12-hour photoperiods, and adult leaves and flowers on 14-hotur photoperiods. Treatment of pliants growing on 8- and 14-houir ...
The effects of environmental nickel toxicity upon survival, growth, reproduction, fecundity, and lifespan of nematodes Caenorhabditis elegans, Pristionchus pacificus, and Caenorhabditis briggsae
(East Carolina University, 2012)
Nickel (II) is a common component of many natural products and man-made devices. Due to its frequent use in everyday life, relatively large amounts of nickel are being released into the environment. Nickel, however, is a ...
