Temp has drastically higher adaptive plasticity than Salt (padj = 0.041) and the difference when compared with Cad is marginally non-significant (padj = 0.065). The “” indicates that the plasticity within the adaptive direction is significant from 0 according to a one-sample t test. (B) Typical |log2FC| for genes anticipated to evolve decreased plasticity in heterogeneous regimes. The variation among regimes isn’t important (p = 0.18), even though the model attributes 30 from the variance to differences amongst regimes (C) Average adaptive distance F for genes expected to boost plasticity. There’s important variation in F across regimes in both diets (cadmium: F = 44.9, df = 3, p = 8.6e-07, 96 from the total variance is attributable to regime effects; salt: F = six.three, df = three, p = 0.008, 72 on the total variance is attributable to regime effects). Inside the cadmium diet regime, F for Salt is significantly higher than for Cad (padj = 1e-06), Temp (padj = 5.8e-06) and Spatial (padj = 1.5e-05). In the salt diet program, F for Cad is drastically larger than for the Salt (padj = 0.009). (D) Average adaptive distance F. for genes expected to reduce plasticity. There’s significant variation in average adaptive distance (F) among regimes in both diets (cadmium: F = 49.three, df = 3, p = five.08e-07, 90 with the total variance is attributable to regime effects; salt: F = 9.8, df = 3, p = 0.0015, 81 of the total variance is attributable to regime effects). Within the cadmium diet, F for Salt is substantially higher than Cad (padj = 1.1e-06), Temp (padj = 1.1e 06) and Spatial (padj = two.8e-05). Inside the salt diet program, F for Cad is drastically higher than for Salt (padj = 0.003), Temp (padj = 0.027) and Spatial (padj = 0.002). doi:10.1371/journal.pgen.1006336.gwhere Od,i may be the expression for the sample representing the “Optimal” state for diet d (i.e., AC in cadmium diet program or AS in salt diet plan) and Nd,i may be the expression for the sample representing the “Non-adapted” state for diet program d (i.e., AS in cadmium diet program or AC in salt diet regime).

We 1st think about the set of 109 genes that we identified as possible targets to evolve improved (adaptive) plasticity. For every single population, we calculated the typical Fd over all the genes of interest for each diet separately. As expected for the constant regimes (Cad and Salt), F values are close to 0 (optimal expression) in their respective adapted diets but the F are far above 0 in the option diets (Fig 4C). Both Temp and Spatial regimes have F values almost as low as the constant regime in its adapted diet plan, particularly in cadmium, offering evidence that heterogeneous populations are also reasonably adapted to each diets for this set of genes.
