"If I had to die - I have had a wonderful life" (Matteo Griggio)
Sadly, Matteo left this life unexpectedly and suddenly on 14 May 2020. Our obituary.
- Multiple signals and Ornament-armament model
- Male mate choice and female quality
- Female condition and variation in female choice of mates
- Preening behaviour and plumage colours
My research has focused primarily on the use of visual signals (plumage colours) in birds communication (both intrasexual and intersexual selection). Based on recent studies a new hypothesis has been developed to explain the evolution of female ornaments independent of male showiness. In this case female ornamentation could be influenced by sexual selection through direct male choice or female-female competition even apart from the classical case of sex-role reversed species. Moreover, female phenotypes may influence the final result of the mate choice because the direct costs and benefits of mating with certain males vary among females. Condition-dependent variation in mate choice may have important evolutionary implications, not only within the same population, but also among populations. There are relatively few experiments, however, of how condition and/or genotype influences female mate choice decisions. Using different study species I'm investigating these two areas of sexual selection.
