A) Unconstrained topology, values along branches indicate bootstrap values (in percent). Only values above 50% are shown. Bar represents 0.125 substitutions per site. B) Constrained tree following topology of Arango and Wheeler (32). See text for details. 2017-10-09 09:54:22 allometry rate of diffusion metabolism pycnogonids oxygen
