Short description Claves de identificación | Morfología | Morfometría

Radios blandos anales: 8. Dionda nigrotaenita is similar to its congener D. serena but differs from it by having eye shorter than snout and 8 anal rays (Ref. 86798).

Inhabits rocky pools, sometimes runs, of headwaters, creeks, and small rivers. Usually occurs among filamentous algae (Ref. 86798).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00501 (0.00232 - 0.01084), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 2.9 ±0.4 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
