  • Spearman's ρ = 0.514, P = 0.029. Kendall's τ a = 0.346, Kendall's τ b = 0.397, Kendall's score = 53, P = 0.037.

  • a μm reported in synonymous substitutions per site per billion years, from Mower et al. (2007).

  • b Independent transfers reported as the number of inferred phylogenetically independent losses of essential mitochondrial ribosomal protein and sdh genes, from Adams et al. (2002).
