Two Year Response Of A Woody Biofuel Plantation To Intensive Management On A Reclaimed Surface Mine In Eastern Kentucky, Joshua Scott Brinks
Two Year Response Of A Woody Biofuel Plantation To Intensive Management On A Reclaimed Surface Mine In Eastern Kentucky, Joshua Scott Brinks
University of Kentucky Master's Theses
The establishment of intensively managed woody energy crops on reclaimed surface mine lands provides an opportunity to diversify domestic biomass sources, while increasing the productivity and economic value of underutilized land. Our objective is to test the effect of fertilization and irrigation on the growth, survival, biomass accumulation, biomass allocation, leaf area, and nutrient dynamics of American sycamore (Platanus occidentalis L.) and black locust (Robinia pseudoacacia L.) planted on a reclaimed surface mine. In 2008, replicated plantings of sycamore and black locust were established on the Big Elk mine in eastern Kentucky. Treatments tested include annual granular fertilizer …
Exotic Invasive Plants In Kentucky, Yu Liang
Exotic Invasive Plants In Kentucky, Yu Liang
University of Kentucky Master's Theses
Invasion of exotic species is a significant problem in natural ecosystems, reaching epidemic proportions and resulting in significant economic losses. However, insufficient knowledge of explicit spatial distribution of invasive species hinders our ability to prevent and/or mitigate future invasion. In this study, we demonstrate the use of existing voluntary data to survey invasive plant species in Kentucky. We also reconstructed the historical distribution of 16 exotic invasive plants typical to Kentucky using herbarium records. We found that Kentucky is facing a large threat from exotic invasive plants as they are reported throughout most counties. The distribution maps for four of …
Genetic Diversity, Structure, And Recolonization Patterns Of Kentucky Black Bears, John Tyler Hast
Genetic Diversity, Structure, And Recolonization Patterns Of Kentucky Black Bears, John Tyler Hast
University of Kentucky Master's Theses
After nearly a century of absence, the black bear (Ursus americanus) reappeared in Kentucky during the late 20th century and has since increased in number. Recolonization of bears in the southeastern portion of the state was thought to have been caused by emigration of bears from adjacent states into the Commonwealth, while in the south-central area, bears originated, or natural recolonization may have been supplemented by the translocation of 14 individuals into the Big South Fork National River Recreation Area. To investigate the recolonization patterns of bears in Kentucky, I used 20 microsatellite loci to determine the genetic …
