Estimates based on models

Preferred temperature (Ref. 123201): 8.8 - 19, mean 13 °C (based on 406 cells).

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00513 (0.00205 - 0.01282), b=3.00 (2.79 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.4 ±0.45 se; based on food items.

Resiliência (Ref. 120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (11 of 100).

Dolicholagus longirostris (Maul, 1948)
