The release of pollutants to natural ecosystems is currently one of the major threats to biodiversity. Economic progress should consider the long-term costs arising from deterioration of ecosystems and the goods and services they provide for human welfare. The traditional way of assessing the impact of pollutants on living systems has focused on evaluating direct effects on test organisms. Nevertheless, organisms are embedded in a network of interactions that serves as routes of propagation of pollutant effects. The impacts of pollutants are transmitted horizontally, through a myriad of ecological interactions, and vertically through parental effects. These considerations drove us to study the direct and indirect effects of pollutants on organisms, populations and communities. We include pollutants as components of ecological systems and study the complex interaction among them and the biological structures. Our research in ecotoxicology uses experimental as well as mathematical modeling tools, at the levels of individuals, populations and communities.


Some topics under development include:


  • Indirect vs. direct effects of pollutants on interacting populations

  • Theoretical community ecotoxicology
  • Transgenerational transfer of pollutant effects

  • Interaction between phenotypic plasticity and tolerance to pollutants
  • Effect of pollutants under variable environments
