Biogeochemical Impact Of Summertime Coastal Upwelling On The New Jersey Shelf, Scott Glenn, Robert Arnone, Trisha Bergmann, Paul W. Bissett, Michael Crowley, Jay Cullen, Joe Gryzmski, Dale Haidvogel, Josh Kohut, Mark A. Moline, Mathew Oliver, Cris Orrico, Robert Sherrell, Tony Song, Alan Weidemann, Robert Chant, Oscar Schofield

Biological Sciences

The alternative hypothesis that observed regions of recurrent hypoxia on the New Jersey inner shelf are more related to coastal upwelling than riverine inputs of nutrients was investigated through a series of multidisciplinary research programs beginning in 1993. The largest variations in ocean temperatures along the New Jersey coast, other than seasonal, are found to be caused by episodic summertime upwelling events driven by southwesterly winds associated with the atmospheric Bermuda High. Off the southern coast of New Jersey, topographic variations associated with ancient river deltas cause upwelled water to evolve into an alongshore line of recurrent upwelling centers that …

Seasonal Steroid Hormone Levels And Their Relation To Reproduction In The Western Diamond-Backed Rattlesnake, Crotalus Atrox (Serpentes: Viperidae), Emily N. Taylor, Dale F. Denardo, David H. Jennings

Biological Sciences

We report seasonal variation in steroid hormone levels in blood samples from free-ranging Western Diamond-backed Rattlesnakes (Crotalus atrox), and the relationship between these hormones and events in the reproductive cycle. At a field site in the Sonoran Desert of south-central Arizona, we collected monthly blood samples over the course of two active seasons from 17 radiotelemetered females, and over three active seasons from 103 randomly encountered males. We used radioimmunoassay to measure plasma levels of 17β-estradiol, progesterone, corticosterone, and testosterone in samples from females, and corticosterone and testosterone in samples from males. Non-reproductive females have consistently low levels …

Bioinformatic Approaches For Objective Detection Of Water Masses On Continental Shelves, Mark A. Moline, Matthew J. Oliver, Scott Glenn, Josh T. Kohut, Andrew J. Irwin, Oscar M. Schofield, Paul W. Bissett

Biological Sciences

As part of the 2001 Hyper Spectral Coupled Ocean Dynamics Experiment, sea surface temperature and ocean color satellite imagery were collected for the continental shelf of the Mid-Atlantic Bight. These images were used to develop a water mass analysis and classification scheme that objectively describes the locations of water masses and their boundary locations. This technique combines multivariate cluster analysis with a newly developed genetic expression algorithm to objectively determine the number of water types in the region on the basis of ocean color and sea surface temperature measurements. Then, through boundary analysis of the water types identified, the boundaries …

Sex–Specific Effects Of Carotenoid Intake On The Immunological Response To Allografts In Guppies (Poecilia Reticulata), Gregory F. Grether, Shinji Kasahara, Gita R. Kolluru, Edwin L. Cooper

Biological Sciences

Rarely are the evolutionary origins of mate preferences known, but, recently, the preference of female guppies (Poecilia reticulata) for males with carotenoid‐based sexual coloration has been linked to a sensory bias that may have originally evolved for detecting carotenoid‐rich fruits. If carotenoids enhance the immune systems of these fishes, as has been suggested for other species, this could explain the origin of the attraction to orange fruits as well as the maintenance of the female preference for orange males. We used the classic immunological technique of tissue grafting to assay a component of the immune response of guppies …

Individual Colour Patches As Multicomponent Signals, Gregory F. Grether, Gita R. Kolluru, Karen Nersissian

Biological Sciences

Colour patches are complex traits, the components of which may evolve independently through a variety of mechanisms. Although usually treated as simple, two-dimensional characters and classified as either structural or pigmentary, in reality colour patches are complicated, three-dimensional structures that often contain multiple pigment types and structural features. The basic dermal chromatophore unit of fishes, reptiles and amphibians consists of three contiguous cell layers. Xanthophores and erythrophores in the outermost layer contain carotenoid and pteridine pigments that absorb short-wave light; iridophores in the middle layer contain crystalline platelets that reflect light back through the xanthophores; and melanophores in the basal …

Serpentine: A Model Habitat For Botanical Research In Sri Lanka, Nishanta Rajakaruna, Alan J. M. Baker

Biological Sciences

Serpentine (ultramafic) outcrops are found in most parts of the world and for many years have attracted the attention of soil scientists and plant biologists alike due to the unusual nature of both the substrate and the life forms they harbour. In this paper, we introduce serpentine outcrops as a model habitat for botanical studies and review preliminary findings of a recently conducted soil and floristic survey of four of the five known serpentine outcrops in Sri Lanka. We hope that this paper will stimulate much-needed studies, both exploratory and experimental, and point to the immediate need for conservation of …

Epidemiology, Pathogenesis, And Prevention Of Foodbome Vibrio Parahaemolyticus Infections, P.S. Marie Yeung, Kathryn J. Boor

Biological Sciences

Since its discovery about 50 years ago, Vibrio parahaemolyticus has been implicated as a major cause of foodborne illness around the globe. V. parahaemolyticus is a natural inhabitant of marine waters. Human infections are most commonly associated with the consumption of raw, undercooked or contaminated shellfish. A few individual V. parahaemolyticus virulence factors, including the thermostable direct hemolysin (TDH) and TDH-related hemolysin (TRH), have been investigated in depth, yet a comprehensive understanding of this organism's ability to cause disease remains unclear. Since 1996, serotype 03:K6 strains have been associated with an increased incidence of gastroenteritis in India and in Southeast …

Effects Of Acid Stress On Vibrio Parahaemolyticus Survival And Cytotoxicity, P.S. Marie Yeung, Kathryn J. Boor

Biological Sciences

For several foodbome bacterial pathogens, an acid tolerance response appears to be an important strategy for counteracting acid stress imposed either during food processing or by the human host. The acid tolerance response enhances bacterial survival of lethal acid challenge following prior exposure to sublethal acidic conditions. Previous studies have revealed relationships between a foodbome pathogen's ability to survive acid challenge and its infectious dose. Vibrio parahaemolyticus is capable of causing gastroenteritis when sufficient cells of pathogenic strains are consumed. This study was designed to characterize acid sensitivities and to compare the effect of sublethal acid exposure (adaptation) on survival …

Neural Networks Satisfying Stone-Weiestrass Theorem And Approximating, Pinal Thakkar

Electronic Theses and Dissertations

Neural networks are an attempt to build computer networks called artificial neurons, which imitate the activities of the human brain. Its origin dates back to 1943 when neurophysiologist Warren Me Cello and logician Walter Pits produced the first artificial neuron. Since then there has been tremendous development of neural networks and their applications to pattern and optical character recognition, speech processing, time series prediction, image processing and scattered data approximation. Since it has been shown that neural nets can approximate all but pathological functions, Neil Cotter considered neural network architecture based on Stone-Weierstrass Theorem. Using exponential functions, polynomials, rational functions …
