Coping with Ineffective Overlap in Multilocus Phylogenetics.

ABSTRACT: Missing data is a long-standing issue in phylogenetic inference, which often results in high levels of taxonomic instability, obscuring otherwise well-supported relationships. Multiple approaches have been developed to deal with the negative effects of ineffective overlap on tree resolution, often by identifying taxa for removal. Here, we repurpose a heuristic method developed to identify unstable taxa in morphological data matrices, concatabominations, and combine it with a novel gene-tree jackknifing on matrix representation of trees to identify candidates for targeted sequencing. Using a multilocus caecilian data set, we illustrate the method's capacity to identify candidate taxa and loci for additional sequencing, compare the results with those of the mathematics-based gene sampling su
