Using information theory to detect rogue taxa and improve consensus trees (2021)
Journal Article
Smith, M. R. (2022). Using information theory to detect rogue taxa and improve consensus trees. Systematic Biology, 71(5), 1088-1094. https://doi.org/10.1093/sysbio/syab099

“Rogue” taxa of uncertain affinity can confound attempts to summarize the results of phylogenetic analyses. Rogues reduce resolution and support values in consensus trees, potentially obscuring strong evidence for relationships between other taxa. In...
