Correlations of fecundity-related measurements to biomass estimations of fitness in literature review. Results depict whether a fecundity measurement was positively, negatively, or insignificantly/equivocally correlated to biomass measurements in 71 total studies that estimated fitness with some type of plant size or performance metric. Fecundity included seed-, fruit-, and flower-related measurements. Height of the bars refers to the number of studies, with percentages (out of 71) included at the top of the bars. Twenty-one studies that estimated plant fitness through plant size or performance did not include any additional fecundity-related measurements (30%).
