Figure 3.
Partitioning of variation of water vapour conductance (GH2O) among avian orders. Dots (one per species) (n = 364) show the distribution of log(GH2O) as a function of (a) adult body mass (g) and (b) residual water vapour conductance (RGH2O) as a function of temperature seasonality. The minimum convex hull is plotted for all species within a subset of avian orders. Silhouette illustrations came from PhyloPic (http://phylopic.org), contributed by various authors under public domain license. (Online version in colour.)
