Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00788 - 0.01457), b=3.09 (3.04 - 3.14), in cm total length, based on LWR estimates for this species (Ref.
93245).
营养阶层 (Ref.
69278): 4.0 ±0.60 se; based on food items.
Generation time: 3.5 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
