We developed an index of biotic integrity based on bird communities in the central Appalachians. As one component of the U.S. Environmental Protection Agency, Environmental Monitoring and Assessment Program's (EPA-EMAP) Mid-Atlantic Highlands Assessment (MAHA), the index is intended to indicate landscape-scale stressors to upland environments in the central(More)
Glycerol as a by-product of biodiesel production is an attractive precursor for producing d-glyceric acid. Here, we demonstrate the successful production of d-glyceric acid based on glycerol via glyceraldehyde in a two-step enzyme reaction with the FAD-dependent alditol oxidase from Streptomyces coelicolor A3(2). The hydrogen peroxide generated in the(More)
1 Abstract A fundamental premise of landscape ecology is that finer-scaled local ecological integrity is directly influenced by larger-scaled land use patterns. Therefore, characterizing landscape patterns that are mapped from satellite imagery may provide valuable covariate information about average integrity " on the ground ". This conjecture was(More)
BACKGROUND Since volatile and rising cost factors such as energy, raw materials and market competitiveness have a significant impact on the economic efficiency of biotechnological bulk productions, industrial processes need to be steadily improved and optimized. Thereby the current production hosts can undergo various limitations. To overcome those(More)
