The general theme of my PhD project is on evolutionary ecology of phenotypic syndromes (integrated patterns of behavioural, physiological and performance traits) in damselflies. The PhD project will concentrate on two questions: (1) Do larval phenotypic syndromes bridge metamorphosis and shape dispersal and mating success? (2) Do population characteristics (#natal habitat effects#) shape phenotypic syndromes and the resulting population differentiation in patterns of dispersal and sexual selection (#geographic selection mosaics#)? Special attention will be given to the comparison of new versus old populations which likely differ in traits related to dispersal. Practical work will be a combination of (1) monitoring natural field populations, and (2) common garden experiments in semi-natural populations (mesocosms / insectaries) and in the laboratory.
