This metadata record presents geochemical analytical data determined during laboratory experiments and a field pilot test collected during 2008-2010 to evaluate degradation of the cyclic nitramine explosive, hexahydro-1,3,4-trinitro-1,3,5-triazine (RDX), and perchlorate in a fractured rock aquifer. These experiments were conducted as part of a study to evaluate the feasibility of enhanced bioremediation for treatment of groundwater contaminants at White Sands Missile Range HTA site, New Mexico. Experiments included two anaerobic microcosm experiments, a culture enrichment test, and field injection test with the dechlorinating culture WBC-2. Data includes concentrations of nitrate, ammonium, perchlorate, RDX, and...
By influencing nutrient mineralization in the soil, decomposers may affect the performance of plants and their associated herbivores. The strength of above–belowground linkages may therefore depend on the availability of nutrients in ecosystems. We investigated the dependency of decomposer- and leaf-herbivore-mediated changes in plant performance on soil nutrient availability in microcosm systems. In separate treatments, Poa annua was used as host plant for the herbivore and was grown in combination with different herb species: Plantago lanceolata, Trifolium repens, and Sanguisorba minor. At three different levels of nutrient availability, the impact of Collembola (Folsomia candida) and aphids (Rhopalosiphum padi),...
