Rodrigues1 criticizes our demonstration2 of low congruence in the global distributions of rare and threatened vertebrates on the grounds that we excluded locations where species counts were zero from our analyses. In practice, this makes no substantive difference to our conclusions. Some sample locations are not inhabited by any organisms of interest: such locations can inflate measures of covariation and association because their values for parameters of interest (in this case, zero counts of species) are identical. This bias has long been known (as ‘the double-zero problem’3); many ecological techniques and studies exclude double-zero data for this reason.
