Bayesian length-weight: a=0.01862 (0.00668 - 0.05187), b=2.96 (2.72 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.7 ±0.52 se; based on food items.
Generation time: 3.3 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回復力 (Ref.
