Effects of gonadal steroids on the expression of courtship display structures and behavior in African mormyrid fish.
One can mimic natural processes of maturation in these fish through sex steroid manipulation, and study the mechanisms that direct structural and behavioral transformations. We are interested in the plasticity of sexual differentiation (sexual dimorphisms) of primary and secondary sexual characters. To this end we expose newly hatched larvae, later juvenile and adult stages to androgen, and also to endocrine disrupting agents. We investigate the expression of gonads, electric organ, electric organ discharge, the anal fin and its support structures, as well as a male-specific fin reflex involved in courtship behavior.
Role of electric organ discharges and their integration with sight and lateral line in African mormyrid fish.
Specific topics: a) maze learning and spatial memory in Gnathonemus petersii and Mormyrus rume; b) impact of stress on memory; c) relationship between memory and the ‘memory molecule’, PKMzeta (with Dr. P. Serrano, Hunter College).
