Fig. 3From: Evolutionary transitions in body plan and reproductive mode alter maintenance metabolism in squamatesDirected acyclic graphs representing nine candidate models compared to disentangle the relationships between five traits through phylogenetic confirmatory path analyses and multi-model inference. M = body mass; SMR = standard metabolic rate; G = animal clade (lizards versus snakes); R = reproductive mode (oviparity versus viviparity); 1/kT = 1/temperatureBack to article page
