Shifts in reproductive strategies in the evolutionary trajectory of plant lineages

Understanding the maintenance and shift in reproductive strategies is a fundamental question in evolutionary research.Although many efforts have been made to compare different reproductive strategies,the association between reproductive strategies and lineage divergence is largely unknown.To explore the impact of different reproductive strategies on lineage divergence,we investigated the evolution of clonality in Saxifraga sect.Irregulares+Heterisia.By integrating several lines of evidence,we found that the loss of clonality in Irregulares+Heterisia was associated with a progressive increase in diversification rate and intraspecific morphological diversity but with a reduction in species distribution range.Our findings provide insights into the ecological and evolutionary effects of different reproductive strategies,suggesting the necessity of integrating clonality into ecological and evolutional research.
