Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.7656 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00372 (0.00150 - 0.00920), b=3.14 (2.92 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.1 ±0.3 se; based on size and trophs of closest relatives
Resiliência (Ref.
120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
