CODE

A food-web approach to assess the effects of disturbance on ecosystem structure, function and stabilther focused on how the disturbance alters aspects of ecosystem structure (e.g. species richness and diversity, food-web connectance, and trophic structure) or ecosystem processes (e.g. nitrogen dynamics and decomposition). Remarkably, few studies have attempted to integrate structure and processes

Scientific basis for extrapolating results from soil ecotoxicity tests to field conditions and the uunder development for the soil ecosystem, refer to Van Straalen and Van Gestel (.). To derive ‘safe’ levels of chemicals in soil ecosystems, a number of extrapolation methods have been developed. These extrapolation methods all assume a certain distribution (log-logistic, log-normal or triangular) o
