Short description Identification keys | Morphology | Morphometrics

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

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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