Genetic diversity: relationship between (A) clonal diversity and proportion of samples with 3× alleles within a meadow relative to salinity, (B) clonal diversity in embryos and percentage of outcrossed families by meadow and (C) variance in outcrossing rates (tm) among P. australis ‘families’ by seagrass meadow. The box corresponds to the lower and upper quartiles (25 and 75th percentiles), internal horizontal bars indicate the median and vertical whiskers extend to the lowest and highest values no further than 1.5 interquartile range. Points outlying this are represented as dots. Abbreviations for range edge meadows in Shark Bay are Guischenault (GU), Red Hill Bay (HP), Denham (DE), Useless Loop (UL), Fowlers Camp (FC) and Perth metropolitan waters are Stark Bay (RST) and Parker Point (RPP) on Rottnest Island, Carnac Island (CI), Walking Beach, Garden Island (WB), Point Peron (PP).
