Box 6125, Morgantown, WV, USA Analysis description: If TerrGas or TerrRunoff was statistically significant for adult females, the restriction sites driving the overall differential methylation were used to correlate the total amount of methylation across restriction sites to Barium (Ba) and Stontium (Sr) heavy concentrations bioaccumulated in waterthrush feathers. Otherwise, all restriction sites were used. The test was limited to waterthrush sampled in 2013 that had both blood samples and Ba and Sr feather data from Latta et al. (2015). A Box-Cox transformation was performed on Ba and Sr data (in ppm) to approach normality using R package car (Fox et al. 2015). We used the transformed Ba and Sr data to conduct a Pearson correlation of the total amount of methylation across restriction sites to Ba and Sr concentrations using R package psych (Revelle 2017) in R (R Core Team 2014). See research article for additional information regarding methdology, terms, and data significance. Data description: Adult females with Strontium (Sr) and Barium (Ba) data from 2013 have Box-Cox transformed ppm values displayed as used in the Pearson correlations. Columns A and B have heavy metal values used in analysis. Column C indicates the number of methylated restriction sites across all restriction sites (n=100). Four adult female recaptures had Ba and Sr data described. Research article relationship: Data referenced in Table 3 and displayed in Fig. 1.
