Figure 1: Phylogenetic tree of 140 taxa present within the database.
From: A comprehensive database of thermal developmental plasticity in reptiles

Tree was derived from TimeTree.org 21. Each of the four major orders are represented in the database (‘blue’ – Crocodilia; ‘red’ – Tuatara; ‘yellow’ – Squamates; and ‘green’ – Testudines). Bars above taxa indicate the number of studies (scaled by a factor of 10) for each species. Note that 15 taxa were excluded because of ambiguity surrounding their taxonomic position.
