Null model results are also provided for comparison, even if not retained in confidence set. All models contained ID as a random effect. Nobs = 95, NID = 57. Abbreviations: HRV = Resting heart rate variability, MPPM = maternal post-partum mass, MDML = maternal daily mass loss rate, PDMG = pup daily mass gain rate, MTE = mass transfer efficiency.
