 \details{
 Operates on nested list-columns of data. The function back-transforms the response variables from the link to the response scale for each dataset in the ManyEcoEvo dataset. The back-transformed data is stored in a list-column called \code{back_transformed_data}. It is useful for when wanting to conduct a meta-analysis on the response scale, e.g. for the \emph{Eucalyptus} count data.
