50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.00830 - 0.04177), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
營養階層 (Ref.
69278): 3.4 ±0.39 se; based on food items.
Generation time: 1.9 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
