Environmental variation associated with genetic variation in all loci of A) Crepidula fornicata and B) C. plana. Bar plot denotes variance explained in redundancy analysis (RDA). Confounded percentage denotes variation that could not be separated between temperature models (summer temperature in C. fornicata and fall temperature in C. plana) and geographic models (latitude). C) Average summer water temperatures were a significant driver of variation for C. fornicata and were correlated with genetic variation of outlier loci using the first MDS axis from Fig. 3. D) Average fall water temperatures were a significant driver for C. plana genetic variation within outlier loci using the first MDS axis from Fig. 3
