Cross-Tolerance towards Environmental Stress: Molecular Mechanisms and Ecological Case Studies
By Lars Tomanek and Hans Pörtner
The topics presented in this symposium range from tolerance towards drought, cold and heat stress in insects to the effects of global warming in marine invertebrates. The studies attempt to provide insights into how exposure to one stress changes the response or the tolerance to another stress. The speakers provide various new methodological approaches of investigating multiple stresses and present recent progress that has been made applying systems biology techniques. In the symposium we are also presenting case studies in which the effect of multiple stresses has been studied in the field. We hope that this symposium brings a new focus on the study of stress physiology in organisms.
