Estimating the timing of early eukaryotic diversification with multigene molecular clocks (2011, background): “Greater data availability also yields more accurate estimates of divergence times because more nodes are available for calibration (29).”
Tree of life for the genera of Chinese vascular plants (2016, background): “In particular, because the tree has sufficiently dense taxonomic sampling, we expect that ecologists can use the tree to study the origin and evolution of Chinese flora, the geographic patterns and conservation of biodiversity, and the structure and dynamics of community (Heath et al., 2008; Lu et a”
Phylogenetic Analysis of the Plastid Inverted Repeat for 244 Species: Insights into Deeper-Level Angiosperm Relationships from a Long, Slowly Evolving Sequence Region (2011, background): “The potential problems and pitfalls of low taxon density for topology estimation and support values are well known (Soltis and Soltis 2004; Leebens-Mack et al. 2005; Heath et al. 2008).”
Improving ITS sequence data for identification of plant pathogenic fungi (2014, background): “Such enhanced taxon sampling carries many advantages (Heath et al. 2008).”
Phylogenetic analysis of 83 plastid genes further resolves the early diversification of eudicots (2010, methodology): “Age estimates for individual clades in a molecular dating analysis can be strongly affected by the number of independent fossil constraints employed, as well as theirproper assignment tonodes in the tree beinganalyzed,which in turn depends heavily on taxon sampling (11, 35, 38, 39).”
Taxonomy and DNA phylogeny of Diatrypaceae associated with Vitis vinifera and other woody plants in Australia (2011, background): “Increased sampling of taxa (within a monophyletic group) has been widely accepted as a means to increase the average accuracy of phylogenies (Rannala et al. 1998; Pollock et al. 2002; Zwickl and Hillis 2002; Heath et al. 2008).”
Phylogeny of the ankylosaurian dinosaurs (Ornithischia: Thyreophora) (2012, background): “a priori taxon exclusion due to the fragmentary nature of fossil specimens, thus controlling for the effects of taxon sampling (Heath et al. 2008).”
Bayesian estimation of fossil phylogenies and the evolution of early to middle Paleozoic crinoids (Echinodermata) (2017, background): “The matrix was constructed in an attempt to maximize sampling across the broad spectrum of taxonomic, morphologic, and preservation gradients while keeping rigorous analysis tractable (Wagner, 2000c; Carlson and Fitzgerald, 2007; Heath et al., 2008).”
Reconstructing the deep-branching relationships of the papilionoid legumes (2013, positive): “Also, a comprehensive taxon sampling potentially improves phylogenetic accuracy because of the increased probability of subdividing long branches (e.g., Graybeal, 1998; Pollock et al., 2002; Zwickl and Hillis, 2002; Heath et al., 2008).”
The revised classification of eukaryotes (2012, background): “Broader taxonomic sampling is likely the most important factor in alleviating these kinds of systematic biases (Heath et al. 2008; Hedtke et al. 2006; Zwickl and Hillis 2002), although adding more taxa may also introduce additional missing sequence data (Wiens 2006).”
Angiosperm phylogeny inferred from sequences of four mitochondrial genes (2010, background): “…the reported high BS values, as this type of analysis tends to produce high support values for whatever relationships the particular taxon sampling scheme leads to, probably because of character over-sampling and taxon under-sampling (Delsuc et al., 2005; Hedtke et al., 2006; Heath et al., 2008).”
