Taxon Cycles in Neotropical Mangroves

open access: yesPlants, 2023
The concept of the taxon cycle involves successive range expansions and contractions over time, through which a species can indefinitely maintain its core distribution. Otherwise, it becomes extinct.

Taxon Influence Index: Assessing Taxon-Induced Incongruities in Phylogenetic Inference [PDF]

open access: yesSystematic Biology, 2012
Understanding the evolutionary history of species is at the core of molecular evolution and is done using several inference methods. The critical issue is to quantify the uncertainty of the inference. The posterior probabilities in Bayesian phylogenetic inference and the bootstrap values in frequentist approaches measure the variability of the ...
