Parameters of CS contributions to UE for birds and butterflies combined (summed total, not weighted total) and compared for birds and butterflies.

These are presented as the number of studies tagged in each category, followed by its proportional representation in the literature as a rounded percentage of either the total number of UE studies (rows 1, 7–8) or the total number of CS studies (rows 2–6). The tags applied for the rows marked with asterisks were not mutually exclusive; hence the percentages do not necessarily tally to 100.
