Plant-Mediated Changes in Soil N-Cycling Genes during Revegetation of Copper Mine Tailings
Nitrogen limitation represents a major bottleneck during the revegetation of mine tailings. However, controls over key nitrogen-cycling genes in rhizospheric soils under differential vegetation management remain poorly understood. The abundance and transcriptional activity of nitrogen-cycling genes and the enzymatic activity of nitrogen transformation are mediated differentially during revegeta...
متن کاملIntegrated management tactics for predicting and alleviating pocket gopher (Thomomys spp.) damage to conifer reforestation plantings
Pocket gophers cause extensive damage to reforestation plantings in the western United States, and pose acute and chronic problems for forest managers. We examine the components of an integrated pest management strategy for reducing pocket gopher damage to conifers: the predictive factors for assessing the risk for damage, techniques for monitoring gopher populations and assessing efficacy of c...

متن کاملRecovery of Copper from Copper Slag and Copper Slag Flotation Tailings by Oxidative Leaching
Copper smelter slag and copper smelter slag flotation tailings were leached using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. Copper extraction from the slag was typically found to be twice as high as that from the slag flotation tailings. Hydrogen peroxide was determined to be the best lixiviant. Thus, copper and iron extractions were ...
