Our results indicate no significant differences in frequency and intensity of seed predation nor in the level of interspecific plant–plant interactions between diploid sexual and triploid asexual populations. Furthermore, there were no consistent latitudinal and/or altitudinal patterns for the assessed parameters. Contrary to our expectations, there were either positive or non-significant associations between genetic diversity and the level of seed predation. To conclude, the RQH cannot thoroughly explain the GP in H. alpinum, and other alternative scenarios should be considered and tested.
