We developed a new method to predict ecological vulnerability in wildlife using autecological information. The method was tested for six chemicals: copper, zinc, cadmium, DDT, chlorpyrifos, and ivermectin. Vulnerability to essential metals copper and zinc was correlated with soil and sediment habitat preference. Vulnerability to bioaccumulating substances cadmium and DDT was correlated with higher positions in the food web and with lifespan. Vulnerability to chlorpyrifos and ivermectin was determined by preference for soil habitats. The ecological vulnerability analysis approach facilitates ordinal ranking of vulnerable species, with ecological relevance. It has potential for further developments in risk assessment.

SOM dynamics represent the balance between the input of plant material (residues, root-derived materials) and the output through decomposition (OM mineralization) by organisms, erosion and leaching. Approximately 20% of global CO2 emissions, one third of global CH4 emissions and two thirds of N2O emissions originate from soils. In many soils, most of the macro-aggregate structure is formed by the activities of soil invertebrates and roots, with important consequences for soil organic matter dynamics, carbon sequestration and water infiltration at several spatial and temporal scales. Current models of SOM dynamics are defined in terms of plant residues input ...

In a previous study we developed a method to predict ecological vulnerability in wildlife using autecological information. In the present study this method is further elaborated from different angles to assess ecological vulnerability in food webs and terrestrial and aquatic ecotopes in the Netherlands. The method was tested for six chemicals: copper, zinc, cadmium, DDT, chlorpyrifos, and ivermectin. Results indicate that trophic groups differ in vulnerability.
