In numerous animal species two or more distinct alternative morphologies can be distinguished between members of the same sex. Such Alternative Reproductive Phenotypes (ARPs) may each come with its own costs and benefits.

My research focusses on the bulb mite Rhizoglyphus robini, here males either develop into a ‘fighter’, which typically competes aggressively with rivals for females, or a ‘scrambler’ which tends to avoid conflict and tries to circumvent rivals. What processes determines the development of either ARP and what costs and benefits come with each ARP are largely unknown. By combining experimental work and mathematical modelling I aim to broaden our knowledge and understanding of ARPs.
