Symposium: Stress, condition and ornamentation

Over the past two decades, the hypothesis that ornamental traits signal the condition of animals has become a prominent paradigm in behavioral and evolutionary biology. At its inception, the concept of condition-dependent signaling was developed with little consideration of the cellular and biochemical mechanisms that might underlie condition. Over this same two-decade period, the study of stress and the mechanisms by which animals cope with stress became a major topic of research among physiological ecologists. In just the past few years, there has been a surge of interest in integrating the insights from physiological studies of stress response, particularly related to endocrine control, immune systems, and oxidative state, with evolutionary investigations of animal ornamentation.

Condition-dependent ornamental signaling is among the hottest topics in both evolutionary and physiological ecology. The unification of cellular and biochemical mechanisms with studies of mate choice and social interactions within the broader investigation of ornamental traits is a very exciting development with particular relevance to the SICB. In this symposium we bring together some of the world's leading experts on the mechanisms that link condition, stress, and ornaments (and armaments).

Sponsors: SICB Divisions: Animal Behavior, Comparative Endocrinology, Ecology & Evolution, and Comparative Physiology & Biochemistry.
