Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00631 (0.00393 - 0.01013), b=2.97 (2.83 - 3.11), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Nível Trófico (Ref.
69278): 3.7 ±0.58 se; based on food items.
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resiliência (Ref.
120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (Assuming tm=1-2, Fec>1,000).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (33 of 100).
