  • a Selected variables (wells and carbon sources) attain at least rank 5 at one or more observation times. A factor weight is the percentage representing a carbon source’s contribution to group differentiation, determined by PCA using five PCs. Each asterisk indicates a significant result of the univariatet test for the given variable at the given observation time (α = 0.05).
