Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00534 - 0.01296), b=3.13 (3.00 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
營養階層 (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Generation time: 11.0 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
