The Sørensen-type overlap quantifies the effective average proportion of a sub-systems OTUs (or lineages in the case of phylodiversities) that is shared across all subsystems. This is thus a metric that quantifies overlap from the subsystems perspective. Its corresponding dissimilarity measure (1 - CqN) quantifies the effective average proportion of nonshared OTUs or lineages in a system. CqN is integrated in the functions beta_dis() and pair_dis().

beta |
A beta diversity value based on Hill numbers. |
qvalue |
The q value used to compute the beta diversity. It needs to be a positive number, usually between 0 and 5, but most commonly 0, 1 or 2. It can be an integer or contain decimals. |
N |
An integer indicating sample size, the number of sampling units to be used to compute the similarity measure. |
