Estimates based on models
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00809 - 0.02051), b=3.06 (2.93 - 3.19), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.6 ±0.53 se; based on food items.
Generation time: 12.1 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resiliência (Ref.
