Table 1.

Parameters estimated from the relationship between skull lengths and molar dimensions, and between trophic level and skull length. Each covariate corresponds to a mean measurement per species i. For multi-level regression formulae, parameter estimates vary by subfamily j, for either Glossophaginae or Lonchophyllinae. HPD, highest posterior density interval; GLS, greatest length of skull; M2L, tooth length; M2W, tooth width (both of complete second upper molar).
