"Recently, two studies have elucidated the relationships between Sunda Island tigers. Xue et al. (2015) showed that balica, sondaica and sumatrae share the same genetic clade but found slight differences (similar to the differences between virgata and altaica) between the islands. A comprehensive study by Wilting et al. (2015) showed that there is no geographical structure amongst these island populations and that they even share haplotypes, and concluded that Sunda Island tigers should be considered consubspecific. Furthermore, Wilting et al. (2015) failed to find support from multiple lines of evidence for mainland subspecies (morphological, molecular and ecological data), but did support the differentiation of Sunda Island tigers."

Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
