marginally significantP = 0.0873
We also recovered a marginally significant relationship between GR gain rates and diet breadth (χ 2 = 6.5620, df = 3–47, P = 0.0873), indicating that broad polylectic species showed higher gain rates than polylectic species (β = 0.00376, SE = 0.00153, t = 2.450, P = 0.0606).
