Integrating Multiple Pressures at Different Spatial and Temporal Scales: A Concept for Relative Ecological Risk Assessment in the European Marine Environment

摘要: ABSTRACT A Relative Ecological Risk Assessment model is presented with an emphasis on risk calculation and characterization. Several types of impacts are incorporated including mortality, competition, disturbance effects at different spatial scales exemplifying fisheries benthic communities, marine mammals, birds. Fisheries sectors analyzed beam trawlers, demersal otter gillnet, sandeel in the German Exclusive Economic Zone North Sea. The basic ecological unit to which score applies population/stock level or distribution range a community. function comprises exposure term loss function. driven by relative term, that is, ratio between negative potential, decline positive recovery. Sensitivity analysis carried out indicate precision its capabilities distinguish high low areas impacts. Limit refe...
