My main interest is the evolution of social structures, but I have (probably far too) many sidelines, such as the systematics/evolution of blennioid fishes, the zoogeography of the marine fauna of Madeira, and crustacean symbioses.

To a limited degree, I would be willing to catch and send marine animals from Madeira - but only in exchange for blennioid fishes from your area, preserved in alcohol (for a molecular genetic study) or against payment.
