Quantifying Nitrogen Cycling On Surface Mined Lands Using Natural Delta 15n Abundances And Fungal Relationships: An Exploratory Study, Alice Jones, Stephanie Jarvis, James Fox, Harold Rowe
Quantifying Nitrogen Cycling On Surface Mined Lands Using Natural Delta 15n Abundances And Fungal Relationships: An Exploratory Study, Alice Jones, Stephanie Jarvis, James Fox, Harold Rowe

The use of isotopes to measure the role of mycorrhizal fungi in cycling nitrogen between soil and plants is applied to a reclaimed surface mine to illustrate the impact of surface mining on soil nutrient cycling in a terrestrial ecosystem. Isotopic relationships between soil, plants, and fungi were examined for a ~10 year old pitch pine reclaimed valley fill in Breathitt County, KY and for an undisturbed mixed mesophytic forest in Letcher County, KY. A quantitative inventory of sporocarps present, their size and substrate was performed at each site. Isotopic signatures of fungal and presumed substrate samples, dominant foliage samples …
Metals Analysis As A Tool For Understanding Headwater Health And Stream Processes In The Southern Appalachian Coal Region: An Exploratory Analysis, Alice Jones, Lee Powell, James Fox
Metals Analysis As A Tool For Understanding Headwater Health And Stream Processes In The Southern Appalachian Coal Region: An Exploratory Analysis, Alice Jones, Lee Powell, James Fox

Major and trace metal analysis was applied to four coal-country headwater streams to better understand the fate of metals in headwater streams affected by mining over time and to determine headwater health. The study watersheds were located in southeastern Kentucky and consisted of an active mine site, a site mined prior to the passage of the Surface Mine Control and Reclamation Act of 1977 (SMCRA), a post-SMCRA reclaimed mine site, and an undisturbed forest control site. Dissolved water metals and suspended sediment metals were sampled at each source, middle, and outlet. Samples were analyzed on an ICP-OES, and spatial trends …

While recent research has focused on the use of carbon capture and sequestration technology feasibility, less focus has been placed upon terrestrial carbon storage affected by coal mining in the context of the clean coal debate. Recent research has shown that the initial disturbance of soil and above-ground carbon pools caused by surface coal mining methods can produce a significant carbon loss from the terrestrial ecosystem, thus increasing the coal carbon footprint of coal. However there is a lack of information regarding the uptake of CO (sub 2) on reclaimed mining sites during re-growth and re-establishment of the soil carbon …
The Microbial Pool And Soil Carbon Cycling On Reclaimed Surface Mine Sites, Alice Jones, Guy Evans, James Fox
The Microbial Pool And Soil Carbon Cycling On Reclaimed Surface Mine Sites, Alice Jones, Guy Evans, James Fox

The southern Appalachian region is an important source of coal resources. The wide scale practice of surface mining in this region leads to the landscape-scale removal of surface material and soils, a large carbon reservoir and important component of the carbon cycle. To date, few scientific studies have examined the development of the soil carbon cycle on post-reclamation mine sites in this region. In particular, development of the microbial pool and its role in carbon cycling in post-reclamation mine soils remains poorly understood. This study measured microbial biomass and soil respiration, as well as bulk soil total organic carbon, total …
