Faster growth Faster life cycle Lower population Higher population Shorter stems Lower reproduction Higher reproduction More dispersion More seeds Higher density Lower survival Thicker and stronger stems Selection for a medium height Stronger and deeper roots Change in colour Change in pollinator Change in dispersion

Lower population Higher population Taller stems
