Estimates based on models
Preferred temperature (Ref.
123201): -1.4 - 1.3, mean 0.5 °C (based on 43 cells).
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00135 (0.00106 - 0.00172), b=3.50 (3.43 - 3.57), in cm total length, based on LWR estimates for this species (Ref.
93245).
Nível Trófico (Ref.
69278): 3.9 ±0.62 se; based on food items.
Generation time: 5.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resiliência (Ref.
120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (Assuming tm<5).
