Experimental tests of sex allocation theory in a simultaneous hermaphroditeanimal

Experimental investigation of factors affecting sex allocation patterns in the flatworm Macrostomum sp., a simultaneous hermaphrodite. Investigated factors are food availability, density and mating group size. Computer assisted image analysis allow to determine sex allocation noninvasively in living animals. Immunocytochemistry is used to link morphological to physiological traits.
