Fig. 4: Genomic vulnerability is reduced for hybrid populations of rainbowfish.
From: Natural hybridization reduces vulnerability to climate change
a–b, Estimates of the allele frequency change required to keep pace with climate change for Melanotaenia eachamensis, Malanda rainbowfish, Tully rainbowfish and M. utcheensis based on the candidate adaptive SNPs for (a) late Holocene to current and (b) current to 2070 (RCP8.5). c, Required change in allele frequency as a function of M. splendida ancestry (R2 = 0.11, P < 0.04). d, Percentage of adaptive alleles (relative to 2070 RCP8.5 climate predictions) absent from pure and hybrid populations. Hollow circles indicate pure populations and crosses show hybrid populations.
