Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00287 - 0.01207), b=3.23 (3.06 - 3.40), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Generation time: 5.9 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resiliência (Ref.
