Final Activity Report Summary - NEPHILID SPIDERS (Nephilid spider phylogenetics as a test for antagonistic coevolution of sexes)
In our research programme, funded by the Marie Curie International Reintegration Grant we focused on nephilid spiders, which we propose as models for evolutionary studies. We presented, tested and found significant support for the hypothesis of sexually antagonistic coevolution of genital and sexual behavioural traits in nephilids through a multifaceted research comprising morphological, ethological and molecular phylogenetic research, and ethological experimentation.
By demonstrating i) coevolution of male and female sexual traits (both morphological and behavioural), and ii) antagonism between the sexes, we provide the evidence for sexually antagonistic coevolution in nephilid spiders although other mechanisms (e.g. cryptic female choice) cannot be excluded. By focusing on phylogenetic pattern, our data are important in establishing new directions of sexual selection and evolutionary research.
The objectives of the project have been met, both scientifically and in terms of a highly successful reintegration of the fellow into European science.
