Response of soil invertebrates to disturbance across three resource regions in North Carolina.
We evaluated the potential of soil microarthropods and enchytraeid worms to be useful as bioindicators of soil condition in forest, wetland, and agricultural ecosystems over a range of ecoregions. Selected mesofauna and soil characteristics in soil and litter in relatively undisturbed and disturbed examples of each of three ecosystems within each of three land resource regions were monitored ov...
متن کاملBiosecurity on Cattle Farms: A Study in North-West England
BACKGROUND Few studies have considered in detail the range of biosecurity practices undertaken on cattle farms, particularly within the UK. In this study, 56 cattle farmers in a 100 km² area of north-west England were questioned regarding their on-farm biosecurity practices, including those relating to animal movements, equipment sharing and companies and contractors visiting the farms. METHO...

Wyant, J.G., Alig, R.J. and Bechtold, W.A., 1991. Physiographic position, disturbance and species composition in North Carolina coastal plain forests. For. Ecol. Manage., 41: 1-19. Relations among physiographic heterogeneity, disturbance and temporal change in forest composition were analyzed on 765 forest stands in the southern coastal plain of North Carolina. Physiographic position strongly r...
متن کاملEvaluating Bioretention Hydrology and Nutrient Removal at Three Field Sites in North Carolina
Three bioretention field sites in North Carolina were examined for pollutant removal abilities and hydrologic performance. The cells varied by fill media type or drainage configuration. The field studies confirmed high annual total nitrogen mass removal rates at two conventionally drained bioretention cells 40% reduction each . Nitrate-nitrogen mass removal rates varied between 75 and 13%, and ...
