Research interests:

My research interests encompass a broad range of aspects relating to amphibian ecophysiology and -toxicology including:

  1. the evaluation of environmental stressors which affect vital rates (growth, development, metabolism, survival),
  2. mechanisms that allow animals to cope with novel environments (phenotypic plasticity and flexibility),
  3. the coupling of species life history, endocrinology, and physiology,
  4. the endocrine disruptive effect of pollutants, and
  5. the development and application of conservation actions.
