Differentiation Of Gene Expression In Behaviorally Isolated Black And Brown Morphs Of Drosophila elegans
(Biology, 2007-09-17)
Pre-zygotic isolation has been recognized as the primary form of incipient speciation, with behavioral isolation as one of its most significant manifestations. In spite of intensive research on behavioral isolation, its ...
Feasibility For Utilization Of A Freshwater Pulmonate Snail, Physa acuta, As A Model Organism For Environmental Toxicity Testing, With Special Reference To Cadmium Ion Toxicity
(Biology, 2007-08-23)
The benefits of developing the pond snail, Physa acuta, as a model species for testing acute and chronic toxicity of aquatic pollutants include its wide North American distribution, ease of field collection and laboratory ...
Anti-viral Capacity Of Quillaja Saponaria Molina Extract Against Vaccinia And Herpes simplex Virus-1
(Biology, 2007-08-23)
It is well known that Quillaja saponins have the ability to elicit a strong immune response when used as an adjuvant in an ISCOM matrix. However, to date, the antiviral capability of Quillaja saponins has not been documented. ...
Population Genetics, Systematics, Biogeography, And Evolution Of The Southeastern Central Texas Eurycea Clade blepsimolge (Plethodontidae)
(Biology, 2007-08-23)
The central Texas Eurycea are a diverse group of perennibranchiate salamanders which inhabit the Edwards Plateau. Although several studies have addressed the systematics and taxonomy of this group, little is known about ...
Use Of Reovirus Monoreassortants To Define Lysis Of Transfomed Cells
(Biology, 2007-08-23)
Reovirus is known to selectively destroy transformed cells while establishing a persistent infection in normal cells. For this study the transformed cell lines used were L929, WI-38 VA13 2RA, T1, N1, and MYC-3. Additionally, ...
Comparing The Melanin-concentrating Hormone -1 Receptor Expression In The Brains Of Mice And Rats
(Biology, 2007-09-17)
The melanin-concentrating hormone (MCH) family of neuropeptides is believed to be important in controlling certain feeding behaviors. Recently, the distribution of melanin-concentrating-1 receptor (MCH-1R) in rat brains ...
Population Genetics Of Phanaeus vindex And P. difformis And Congruence With Morphology Across A Geographic Zone Of Species Overlap
(Biology, 2007-08-23)
Amplified Fragment Length Polymorphisms (AFLPs) reveal that the rainbow scarabs Phanaeus vindex (MacLeay) and Phanaeus difformis (LeConte) are distinct evolutionary units which occur in sympatry at the Fort Worth Nature ...
Comparison Of The Ingestion And Digestion Rates Of Ochromonas danica Grazing On Pseudomonas fluorescens Of Varying Food Quality
(Biology, 2007-08-23)
Flagellate prey selection appears to depend on morphological characteristics of prey such as cell size and motility, as well as on physiochemical characteristics such as digestibility and cell surface characteristics. ...
Efficacy Of Selected Natural And Synthetic Novel Organic Compounds In Prevention Of Zebra Mussel (Dreissena Polymorpha) Macrofouling By Byssal Attachment Inhibition
(Biology, 2007-10-08)
The invasive, freshwater, bivalve, Dreissena polymorpha (zebra mussel) was introduced to North America in the Great lakes in 1986 and has since spread throughout the waterway of the eastern and central United States and ...
Proximate And Ultimate Mechanisms Associated With Female Secondary Coloration In The Mexican Boulder Spiny Lizard, (Sceloporus pyrocephalus)
(Biology, 2007-08-23)
Secondary sexual coloration is thought to be the result of runaway selection for signals that honestly communicate relative fitness. Much theoretical work suggests sexual selection has driven conspicuous secondary traits ...
