The course will provide an updated review and synthesis of the current state of ecotoxicology of chemical contaminants and and ecological risk assessment in amphibians and reptiles. It will also give an overview on different methodologies used to collect animals in the field, to culture them in the laboratory, and to generate ecotoxicological data. All the information will be complemented with the presentation of national and international case studies. Leer más.
