Bisphenol A: vom Saal and Hughes Respond
(East Carolina University, 2006-01)
Convergent evolution of bright coloration and toxicity in frogs
(East Carolina University, 2003-10-28)
An Extensive New Literature Concerning Low-Dose Effects of Bisphenol A Shows the Need for a New Risk Assessment
(East Carolina University, 2005-08)
Bisphenol A (BPA) is the monomer used to manufacture polycarbonate plastic, the resin lining of cans, and other products, with global capacity in excess of 6.4 billion lb/year. Because the ester bonds in these BPA-based ...
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 ...
Tactical reproductive parasitism via larval cannibalism in Peruvian poison frogs
(East Carolina University, 2009-04-23)
We report an unusual example of reproductive parasitism in amphibians. Dendrobates variabi- lis, an Amazonian poison frog, oviposits at the surface of the water in small pools in plants and deposits tadpoles within the ...
Identification of the Cu(II) Coordinating Residues in the Prion Protein by Metal-Catalyzed Oxidation Mass Spectrometry: Evidence for Multiple Isomers at Low Cu(II) Loadings
(East Carolina University, 2008-09-02)
While the Cu(II) binding sites of the prion protein have been well studied under Cu-saturation conditions, the identity of the residues involved in coordinating Cu(II) at low stoichiometries and the order in which the ...
Controls on Septic System Wastewater Treatment and Shallow Groundwater Quality in Coastal North Carolina
(East Carolina University, 2009)
Excess nitrogen and bacteria concentrations in coastal waters of North Carolina have led to eutrophic conditions, fish kills, and the closure of shellfish waters. Regulatory efforts by the state to reduce nitrogen and ...
