Ephemeroptera Culturing Methods: Development Of Culturing And Rearing Methodology And High Sulfate Simulated Mine Effluent Toxicity Test Using Field Collected Water, Daniel Edward Brady
Ephemeroptera Culturing Methods: Development Of Culturing And Rearing Methodology And High Sulfate Simulated Mine Effluent Toxicity Test Using Field Collected Water, Daniel Edward Brady
Theses, Dissertations and Capstones
Ephemeroptera taxa are not frequently used in toxicity testing; however, some mayfly taxa may be more sensitive to aquatic pollutants than standard test organisms used to determine anthropogenic effects on aquatic ecosystems. Additionally, some standard test organisms are not native to the Appalachian region and may not be truly reflective of the effects on native organisms. With mayflies not being the typical test organism, there is not a great deal of literature on culturing methods for this organism. For a standard acute toxicity test, there must be 80% survival within the control organisms for the test to be considered viable. …
Using Molecular Diet Analysis To Inform Invasive Species Management: A Case Study Of Introduced Rats Consuming Endemic New Zealand Frogs, Bastian Egeter, Cailín Roe, Sara Peixoto, Pamela Puppo, Luke J. Easton, Joana Pinto, Phillip J. Bishop, Bruce C. Robertson

The decline of amphibians has been of international concern for more than two decades, and the global spread of introduced fauna is a major factor in this decline. Conservation management decisions to implement control of introduced fauna are often based on diet studies. One of the most common metrics to report in diet studies is Frequency of Occurrence (FO), but this can be difficult to interpret, as it does not include a temporal perspective. Here, we examine the potential for FO data derived from molecular diet analysis to inform invasive species management, using invasive ship rats (Rattus rattus) …
Consumption Of High Ω-3 Fatty Acid Diet Suppressed Prostate Tumorigenesis In C3(1) Tag Mice, Juliana A. Akinsete, Gabriela Ion, Theodore R. Witte, W. Elaine Hardman
Consumption Of High Ω-3 Fatty Acid Diet Suppressed Prostate Tumorigenesis In C3(1) Tag Mice, Juliana A. Akinsete, Gabriela Ion, Theodore R. Witte, W. Elaine Hardman
Biochemistry and Microbiology
Prostate cancer incidence and mortality are high in the Western world and high ω-6/ω-3 PUFA in the Western diet may be a contributing factor. We investigated whether changing from a diet that approximates ω-6 fat content of the Western diet to a high ω-3 fat diet at adulthood might reduce prostate cancer risk. Female SV 129 mice that had consumed a high ω-6 diet containing corn oil for 2 weeks were bred with homozygous C3(1)Tag transgenic male mice. All male offspring were weaned to the corn oil diet (CO) until postpuberty when half of the male offspring were transferred to …
Maternal Consumption Of Canola Oil Suppressed Mammary Gland Tumorigenesis In C3(1) Tag Mice Offspring, Gabriela Ion, Juliana A. Akinsete, W. Elaine Hardman
Maternal Consumption Of Canola Oil Suppressed Mammary Gland Tumorigenesis In C3(1) Tag Mice Offspring, Gabriela Ion, Juliana A. Akinsete, W. Elaine Hardman
Biochemistry and Microbiology
Background: Maternal consumption of a diet high in omega 6 polyunsaturated fats (n-6 PUFA) has been shown to increase risk whereas a diet high in omega 3 polyunsaturated fats (n-3 PUFA) from fish oil has been shown to decrease risk for mammary gland cancer in female offspring of rats. The aim of this study was to determine whether increasing n-3 PUFA and reducing n-6 PUFA by using canola oil instead of corn oil in the maternal diet might reduce the risk for breast cancer in female offspring.
Methods: Female SV 129 mice were divided into two groups and placed on …
The Importance Of Fallback Foods In Primate Ecology And Evolution, Paul J. Constantino, Barth W. Wright
The Importance Of Fallback Foods In Primate Ecology And Evolution, Paul J. Constantino, Barth W. Wright
Biological Sciences Faculty Research
The role of fallback foods in shaping primate ranging, socioecology, and morphology has recently become a topic of particular interest to biological anthropologists. Although the use of fallback resources has been noted in the ecological and primatological literature for a number of decades, few attempts have been made to define fallback foods or to explore the utility of this concept for primate evolutionary biologists and ecologists. As a preface to this special issue of the American Journal of Physical Anthropology devoted to the topic of fallback foods in primate ecology and evolution, we discuss the development and use of the …
Ecology And Morphological Comparison Between Rough Greensnakes (Opheodrys A. Aestivus) And Eastern Smooth Greensnakes (Opheodrys V. Vernalis) In West Virginia, Timothy Earl Baldwin
Ecology And Morphological Comparison Between Rough Greensnakes (Opheodrys A. Aestivus) And Eastern Smooth Greensnakes (Opheodrys V. Vernalis) In West Virginia, Timothy Earl Baldwin
Theses, Dissertations and Capstones
Since 1971, documented Rough Greensnake (Opheodrys aestivus) occurrences in West Virginia have declined from approximately 100 to less than 20 occurrences in the last 10 years. In contrast to the decline of Rough Greensnakes in WV, Smooth Greensnake (O. vernalis) populations appear to be stable over the same period of time. Historic sites from the West Virginia Biological Survey were cross referenced with habitat descriptions in published literature to establish research locations. One hundred nineteen Rough and Smooth Greensnakes were measured for snout-vent length and total body length, and of these, 78 were measured in detail for external head morphology …
