Population Dynamics And Future Viability Of The Eastern Massasauga Rattlesnake (Sistrurus Catenatus) In Southwest Michigan, Matthew John Klein
Population Dynamics And Future Viability Of The Eastern Massasauga Rattlesnake (Sistrurus Catenatus) In Southwest Michigan, Matthew John Klein
Graduate Theses, Dissertations, and Problem Reports (ETD)
Managing at-risk species or populations requires understanding the demographic and genetic drivers of long-term population trends. The eastern massasauga rattlesnake (Sistrurus catenatus) is a federally threatened species facing multiple interacting threats across its range. Habitat loss from wetland drainage and agricultural land conversion has caused range contractions and geographic isolation of populations. Because remaining populations are often small and widely separated, most are now genetically isolated, threatening their long-term viability. Reversing these declines requires understanding population dynamics, quantifying extinction risk, identifying drivers of long-term viability, and assessing the effects of inbreeding and the potential for genetic rescue to …

A Systematic Method For Measuring Gentrification Using Building Permits Data: A Washington D.C Case Study, Andey Fomil
Graduate Theses, Dissertations, and Problem Reports (ETD)
Gentrification can significantly alter the socioeconomic, demographic, and commercial aspects of a city. It is a complex process that transforms the characteristics of entire neighborhoods, modifying not only the observable physical aspects, but also the community structure. Traditional quantitative gentrification measurement approaches assess the process through analysis of Census demographic indicators coupled with field visit analysis of the physical built environment. This study proposes a new gentrification measuring approach that combines traditional Census indicators with a new indicator in the form of City Building Permits. Two GIS spatial analysis techniques are utilized to evaluate the effectiveness and accuracy of the …
Trees, Fungi, Insects: How Host Plant Genetics Builds A Community, Sandra Jeanne Simon
Trees, Fungi, Insects: How Host Plant Genetics Builds A Community, Sandra Jeanne Simon
Graduate Theses, Dissertations, and Problem Reports (ETD)
Organisms, such as fungi and insects, can cause millions of acres of agricultural and forest damage, while others provide billions of dollars in ecological services such as education, aesthetic enjoyment, pollination, and gardening. Plant breeding and biotechnology can potentially help establish a balance between the proliferation of detrimental pests and attraction of beneficial insects. Variation in plant physiological and morphological characteristics are extremely important in the ability of host tissues to support many different types of organisms. When that variation is genetically heritable in a plant population, shifts in the underlying genes can have predictable consequences in structuring entire ecosystems. …

Animal Dispersal Of American Ginseng (Panax Quinquefolius L.), Amy M. Hruska
Graduate Theses, Dissertations, and Problem Reports (ETD)
American ginseng (Panax quinquefolius L.) is a long-lived forest herb found throughout Appalachia, well-known for its reputation as a medicinal plant species. Harvest of ginseng for the international medicinal plant trade has been a significant contributor to population decline of the species. As a declining species with life-history traits similar to many other herbaceous perennials and both cultural and economic value, American ginseng has become a focal species for many demographic and conservation based studies. Seed dispersal is a critical component of ginseng demography lacking empirical evidence for potential dispersal mechanisms. To date, gravity is considered to be the primary …

It also sought to determine if any relationship existed between participants' perceptions of beliefs and their choices of teaching positions. Pre-service students in special …
Demographic Response Of American Ginseng (Panax Quinquefolius L.) To Climate Change, Sara Souther
Demographic Response Of American Ginseng (Panax Quinquefolius L.) To Climate Change, Sara Souther
Graduate Theses, Dissertations, and Problem Reports (ETD)
Ecological response to recent climate change has been documented for a multitude of species worldwide. Climate models predict further increases in temperature, as much as 8 times the degree of warming that has already occurred. Given observations of species response to contemporary climate change and the unprecedented degree of warming expected over the next century, climate change will no doubt determine future ecosystem composition and affect global species diversity. In order to prevent loss of biodiversity, it is necessary to understand and accurately project species' response to climate, and to identify species that are vulnerable to climate change driven extinctions. …

Genetic Characterization, Ginsenoside Analysis And Micropropagation Of American Ginseng (Panax Quinquefolius L.), Samuel G. Obae
Graduate Theses, Dissertations, and Problem Reports (ETD)
American ginseng (Panax quinquefolius L.), is an economically important medicinal plant native to eastern deciduous forests of North America. Like many other medicinal plants worldwide, P. quinquefolius is mainly collected from the wild. And because of its growing demand, abundance of wild populations is threatened with over harvesting. In West Virginia, P. quinquefolius is available both in cultivation and in the wild. Even though P. quinquefolius occurs in all 55 counties in West Virginia, patterns of its harvesting and cultivation vary across the state. As described in chapter 2, the genetic diversity and population structure of P. quinquefolius under two …

A Panax-Centric View Of Invasive Species And A Case Study On The Effects Of Garlic Mustard (Alliaria Petiolata), Kerry Lynn Wixted
Graduate Theses, Dissertations, and Problem Reports (ETD)
American ginseng (Panax quinquefolius L.) is a long-lived, valuable herb found throughout the eastern United States. Habitat degradation, harvest pressures, overbrowsing by deer and reduced genetic diversity are believed to be the primary causes of decline for this rare species; however the widespread threat of invasive species has yet to be investigated. Therefore, my research focused on examining the level of exposure of individuals and populations of ginseng to invasive plant species as well as partitioning the effects of a particular invasive, garlic mustard (Alliaria petiolata ), into those owing to competition and allelopathy. For my first study, I used …
Genetic And Evolutionary Consequences Of Harvest In American Ginseng, Panax Quinquefolius L. (Araliaceae), Emily H. Mooney
Genetic And Evolutionary Consequences Of Harvest In American Ginseng, Panax Quinquefolius L. (Araliaceae), Emily H. Mooney
Graduate Theses, Dissertations, and Problem Reports (ETD)
American ginseng (Panax quinquefolius L.) is a wild-harvested perennial plant of the eastern deciduous forest. Harvest supplies world markets with roots used in Asian medicine, but this practice is fatal to plants. The objective of this research was to investigate the genetic and evolutionary consequences of harvest. As seen in animal species, harvest may alter size selection by preferentially removing large individuals. Chapter 2 describes my study of harvest's effects on size selection. From the simulated harvests, I observed that large-sized plants lose their fitness advantages in harvested populations. Harvest pressure could ultimately lead to population divergence if selected traits …

An Ecological Study Of Panax Quinquefolius In Central Appalachia: Seedling Growth, Harvest Impacts And Geographic Variation In Demography, Martha E. Van Der Voort
Graduate Theses, Dissertations, and Problem Reports (ETD)
American ginseng (Panax quinquefolius L.) is a long-lived, slow-maturing understory perennial herb found in eastern North American forests. The economic value of P. quinquefolius on the world market has remained strong for nearly 300 years. It has high economic and social value in the central Appalachians as well. Persistent harvest of ginseng combined with habitat loss has reduced populations in the wild, threatening the future of the species and its continued harvest. American ginseng was placed on the CITES Appendix II list in 1973 due to population declines. These concerns led to a series of studies investigating the population dynamics …
Pharmaceutical Performance Testing Of Commercially Available Calcium Supplements, Jianqing Liu
Pharmaceutical Performance Testing Of Commercially Available Calcium Supplements, Jianqing Liu
Graduate Theses, Dissertations, and Problem Reports (ETD)
In our research, the quality of a number of calcium supplements was evaluated by their physical properties, disintegration and dissolution profiles. Physical tests and disintegration did show a pH sensitivity. Disintegration confirmed the good uniformity of the products. In the USP required dissolution test, most of the products did not achieve acceptable drug release in the specified time period. While formulation factors and the salt form of calcium supplements can to some extent affect their dissolution pattern, it was ultimately considered that the failure may be related to the poor solubility of the calcium salts.;Based on the results and the …
Effects Of Herbivory By White -Tailed Deer (Odocoileus Virginianus Zimm.) On The Population Ecology And Conservation Biology Of American Ginseng (Panax Quinquefolius L.), Mary Ann Furedi
Graduate Theses, Dissertations, and Problem Reports (ETD)
American ginseng (Panax quinquefolius L.) is a long-lived understory herb considered rare within its range. Harvesting pressures and habitat degradation/destruction are thought to be the primary causes of population decline although others factors such as browsing by white-tailed deer (Odocoileus virginianus Zimm.) have not yet been explored. To understand the effects of deer browsing on natural ginseng populations, my research focused on four specific objectives. First, I investigated how plant characteristics and microsite conditions influence the susceptibility to being browsed. I found that apparency plays a role in influencing browse selection, such that large, reproductive plants in visible and accessible …
