"An example of the limitations of #interspecific patterns in #scaling studies is that they remain unconnected from the primary assumption that there is #StabilizingSelection for a constant #allometric #exponent of ¾ and #NaturalSelection acts within populations, not between species."

Broad variability but a moderate plasticity in the #allometric exponents were also observed across genotypes and environments. #Exponents were impacted by water deficit, but not temperature. #Genotypes that deviated from #MST predictions exhibited more plasticity in trait-size relationships than genotypes that followed #MST predictions.
