Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

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).

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

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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