The Cape Fear shiner <i>Notropis mekistocholas</i> is a recently described cyprinid fish endemic to the Cape Fear River Basin of North Carolina. Only five declining populations of the fish remain, and therefore, it has been listed as endangered by the U.S. Government. Determining habitat requirements of the Cape Fear shiner, including physical habitat and water quality, is critical to the species survival and future restoration. This study integrated the sciences of t...

The purpose of the research was to determine if shortnose sturgeon, <i>Acipenserbrevirostrum</i>, occur within the Neuse River, North Carolina. Shortnose sturgeon historicallyoccurred in most major Atlantic Coast rivers from Saint Johns River, New Brunswick,Canada to St. Johns River, Florida. Anecdotal evidence suggests that a population ofshortnose sturgeon once occurred in the Neuse River, North Carolina, but their current statuswas unknown. In compliance with the N...

Isotopic analyses of bone phosphate oxygen from a modern alligator, ostrich, and elephant have provided a means for examining diagenesis and thermoregulatory strategy within the dinosaur Acrocanthosaurus atokensis. The Acrocanthosaurus specimen is assumed to retain an original isotopic signature, based on a lack of linear correlation between �_18Ophosphate and structural �_18Ocarbonate, equal standard deviations between �_18Ophosphate values for spongy and compact bone, and a significant differe...

American Oystercatchers are listed as a Species of High Concern by the U. S. Shorebird Conservation Plan, in part because of threats during the breeding season. Oystercatchers nest on the sandy beaches of the East Coast of the United States and their nesting habitat is under increasing threat from human development and human disturbance. In this study, I analyzed 8 seasons of reproductive success data for American Oystercatchers in North Carolina. I identified the primary causes of nest failure ...

Unmanned aerial vehicles (UAVs) have become increasingly popular for many applications, including search and rescue, surveillance, and electronic warfare, but almost all UAVs are controlled remotely by humans. Methods of control must be developed before UAVs can become truly autonomous. While the field of evolutionary robotics (ER) has made strides in using evolutionary computation (EC) to develop controllers for wheeled mobile robots, little attention has been paid to applying EC to UAV control...

Chlorinated aliphatic hydrocarbons (CAH) are among the most common and difficult to treat contaminants in soil and groundwater. The available information suggests that edible oil permeable reactive barriers (PRBs) can be a very cost effective approach for plume control because of their low capital and O&M costs. However important issues need to be addressed to assure its efficiency.This work will address permeability losses and oil retention along with oil distribution in the subsurface ...

ABSTRACTHydrophobic organic pollutants (HOPs) are in general characterized by high toxicity, long environmental half-life and high bio-accumulation factors. Due to their hydrophobicity, HOPs tend to sorb onto particulates in natural aquatic environment and their degradation pathways and rates are altered with the change of the reaction media and the settlement of these particles. The influence of the dissolved organic matters (DOMs), termed as the third phase, on the sorption partition coefficie...

In general the acoustic wave is used as a detecting tool in the ocean, its application placing a sound source into ocean, then the sound may impinge involves the target by wave propagation in the ocean. Due to the reflection and scattering effect of target, part of acoustic energy will be received by transducer through the path of reflection. The goal of target identification can be achieved by signal processing finally. If a submarine wish to avoid the detection by sonar system , it should atte...

ABSTRACTHydrophobic organic pollutants (HOPs) are in general characterized by high toxicity, long environmental half-life and high bio-accumulation factors. Due to their hydrophobicity, HOPs tend to sorb onto particles in environment. The influence of the dissolved organic matters (DOMs) on the sorption partition coefficient is observed because of their interactions with HOPs. This binding between DOM and HOPs increases apparent solubility and mobility of the HOPs in natural aquatic system. On t...
