Stress indices in different biological organization levels are analyzed as tools in ecotoxicological studies. Individual stress indices of high organization levels are proposed to obtain a confident knowledge of the damages or disadvantages caused by pollutants on individual organisms, under the assumption that any disadvantage (caused by stress agents) on individuals provide a confident evidence of a detrimental condition of the population. Particularly, relevant individual animal responses related with changes of the use of environmental resources, alterations of avoidance responses, shifts of biotic preferences, and decrease on functional capacity and performance are proposed as useful indices in ecotoxicological studies.
