Short description Bestämningsnycklar | Morfologi | Morfometri

Dionda argentosa is genetically distinct but morphologically indistinguishable from Guadalupe roundnose minnow, D. nigrotaeniata (Ref. 86798).

Inhabits rocky pools, sometimes runs, of headwaters, creeks, and small rivers. Found 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 (0.00242 - 0.01036), b=3.11 (2.92 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

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

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

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