Different generalized linear models (GLMs) showing the relationship between the genome-wide rate of recombination (log-transformed), the expected heterozygosity (H_e) at SSRs and the life-form of 81 higher plant species.

^a In these two models, all trees (conifers and angiosperms) were considered as a single life-form, which was fixed as baseline for the contrasts.

^b In this model, the conifer and angiosperm trees were considered as separate "life-forms". The angiosperm trees were fixed as baseline for the contrasts.
