Differentiation measures are the abundance-based local differentiation measure (1−CqN) and regional differentiation measure (1−UqN) obtained from partitioning Hill numbers [36];

--- No measures for q = 1 and q = 2 because species abundances are not considered for measures based on function (F) only.
