Behavioural antioxidant strategies to cope with high temperatures: a study in a tropical butterfly

Exposure to high temperatures can disrupt the balance between the production of reactive oxygen species (ROS) and antioxidant defences. Animals may be able to correct such an imbalance physiologically by up-regulating endogenous antioxidant defences. They may also respond behaviourally by increasing the intake of dietary antioxidants (e.g. polyphenols) and/or by reducing physical activity (thereby decreasing ROS production). The use of a given...
