Fig. 1.

Scaling of water loss to gas exchange—O₂ for animals and CO₂ for plants (n = 202). Solid lines represent lines from a fitted linear model that allowed interactions between group (plants, mammals, etc.) and log₁₀(gas uptake rate). The labeled points are outliers that were not included in the formal modeling. They are Blatella germanica (German cockroach; 1), Bolborhynchus lineola (lineolated parakeet; 2), Falco mexicanus (prairie falcon; 3), Tursiops truncatus (bottlenose dolphin; 4), and Delphinapterus leucas (beluga whale; 5).
