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 ...
Comparison of quantification methods to measure fire-derived (black/elemental) carbon in soils and sediments using reference materials from soil, water, sediment and the atmosphere
(2007)
Black carbon (BC), the product of incomplete combustion of fossil fuels and biomass (called elemental carbon (EC) in atmospheric sciences), was quantified in 12 different materials by 17 laboratories from different ...
Ecological effects of rising sea level on shorezone
(East Carolina University, 2009)
This study examines the ecological effects of sea-level rise on shorezone in the Neuse River estuary and western Pamlico Sound, NC. Shorezone is defined here in an ecohydrological context as the area of wetland that extends ...
Oceanic loading of wildfire-derived organic compounds from a small mountainous river
(2008)
Small mountainous rivers (SMRs) export substantial amounts of sediment into the world's oceans. The concomitant yield of organic carbon (OC) associated with this class of rivers has also been shown to be significant and ...
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. ...
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)
The moderating effects of religiosity on the relationship between stressful life events and delinquent behavior
(East Carolina University, 2008)
Previous research has shown that many forms of strain are positively related to delinquency. Evidence also suggests that religiosity buffers the effects of strain on offending, but this issue requires further research. ...
Concerted gene recruitment in early plant evolution
(East Carolina University, 2008-07)
Background: Horizontal gene transfer occurs frequently in prokaryotes and unicellular eukaryotes. Anciently acquired genes, if retained among descendants, might significantly affect the long-term evolution of the recipient ...
