Common garden
A common garden experiment was initiated in which pollination and herbivory were manipulated to examine phenotypic selection on nine plant attractive and defence-related traits in F. vesca . Four blocks were established containing 81 clonally-replicated plant genotypes each (listed in Table S1). We employed a split-plot design in which two pollination treatments (control versus hand pollination) were applied within blocks, and two herbivory treatments (addition versus removal) were applied across blocks, to afford a total of four unique treatment combinations. Details of the common garden establishment, and sourcing and propagation of plant genotypes from wild Swedish populations, are provided in Appendix 1.
