Microevolutionary processes in natural populations of the waterstrider Aquarius remigis
… body size is determined by the net effect of selection acting throughout the life history of the organism. Body size is correlated between the sexes, and sexual size dimorphism (SSD) provides natural experiments in the evolution of traits constrained by genetic correlations. In this thesis I …
