Última Protozoa as test organisms in marine ecotoxicology: luxury or necessity? OMA Dive, D.; Persoone, G.. A critical examination of the utility of protozoan bioassays in marine as well as in freshwater ecotoxicology implies the answer to three basic questions: why, how and when. Arguments in favor of tests with Protozoa are: protozoans combine all biological mechanisms and functions in one single cell; the physiology and biochemistry of several species has been studied extensively; the generation time of Protozoa is very short in comparison to Metazoa; large numbers of organisms can be produced in a small volume; induction of cryptobiotic stages is possible with some species; Protozoa play a significant role in aquatic ecosystems; test methodologies with very sensitive criteria can be worked out. The two basic approaches for bioassay are <i>in... Tipo: Info:eu-repo/semantics/article Palavras-chave: Ecotoxicology; Test organisms; Protozoa.
