Estimates based on models

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01950 (0.00780 - 0.04874), b=3.01 (2.82 - 3.20), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 2.6 ±0.24 se; based on food items.

Resiliência (Ref. 120179): Elevada, tempo mínimo de duplicação da população menor que 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).

Tylochromis variabilis Stiassny, 1989
