The Growth, Yield, And Financial Performance Of Isolated Eastern White Pine (Pinus Strobus L.) Reserve Trees, Christopher E. Zellers

Electronic Theses and Dissertations

The ability of eastern white pine (Pinus strobus L.) to persist as emergent trees makes this species well suited to silvicultural systems in which they are retained as isolated reserves after a regeneration harvest. While such systems are implemented throughout the Acadian spruce-fir region of Maine, little is known about the growth response and financial performance of eastern white pine following complete release from competition. In this study, 77 trees from 8 sites throughout the Acadian spruce-fir region were sampled tree and crown measurements, and increment cores were extracted at breast height, as well as from the top of …

Intent To Continue Growing Switchgrass As A Dedicated Energy Crop: A Case Study Of Switchgrass Producers In East Tennessee, Jessica Elise Fox

Masters Theses

Efforts to reduce the United States’ dependence on foreign petroleum encourage the production of fuels from bioenergy crops. Recent energy mandates have therefore “opened doors” for alternative feedstock sources for ethanol production. Switchgrass is a candidate feedstock. Under the University of Tennessee’s Biofuels Initiative, the University of Tennessee, partnering with DuPont-Danisco Cellulosic Ethanol LLC, contracted for the production of switchgrass with local farmers to guarantee biomass feedstock supply for an ethanol conversion research facility. This study used methods borrowed from the social psychology literature in combination with economic theory to analyze factors influencing switchgrass farmers’ intentions to continue growing switchgrass …

Overall familiarity with ethanol as an alternative fuel is high; however, individual segments vary on beliefs …

The Assumption Of Non-Coerciveness And The Total Food Market, Harwood Schaffer

Doctoral Dissertations

For the last 46 years, the countries of the world have tried to reduce the number of chronically hungry people. Despite all the efforts, the numbers have barely budged from the over 850 million people who were chronically hungry in 1974 until the 2007-2009 food price crisis, when the numbers increased to over 1.02 billion. The blame for this situation has variously been put on bad governance, the lack of adequate market reforms, the market reforms that were imposed on developing nations, and globalization. Food, like other products in this globalized world, is allocated using the market system. One likely …

Evaluating Native Wheatgrasses For Restoration Of Sagebrush Steppes, Jayanti Ray Mukherjee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pseudoroegneria spicata and Elymus wawawaiensis are two native perennial bunchgrasses of North America's Intermountain West. Frequent drought, past overgrazing practices, subsequent weed invasions, and increased wildfire frequency have combined to severely degrade natural landscapes in the region, leading to a decline in the abundance of native vegetation. Being formerly widespread throughout the region, P. spicata is a favorite for restoration purposes in the Intermountain West. Elymus wawawaiensis, which occupies a more restricted distribution in the Intermountain West, is often used as a restoration surrogate for P. spicata. However, since most restoration sites are outside the native range of …

The Consequences Of Increasing Ocean Acidification On Local And Global Fishing Industries, Alyson N. Stark

CMC Senior Theses

As human activities continue to generate accelerating levels of carbon dioxide emissions, the world’s oceanic resources are threatened by variability in seawater chemistry, known as ocean acidification. Recent increases in atmospheric carbon dioxide have resulted in decreased carbonate ion concentrations and ocean pH levels, leading to increasingly acidic waters. The exact consequences of these chemical changes on ecosystems and individual species are difficult to predict; however, research has shown that economically valuable calcifying species will experience reduced reproductive fitness and population declines. Ocean acidification, therefore, poses an immediate risk to both fish stocks and fishery industries. From a local perspective, …
