Korte beschrijving Morfologie | Morfometrie

This species is distinguished from G. oelemariensis subgenus Oelemaria) by possessing 2 supraneural bones and a midlateral bar and a midlateral spot (vs. absence of a midlateral bar in G. oelemariensis). G. stergiosi is distinguished from all other species in the subgenus Guianacara by possessing of a round midlateral spot placed almost entirely below the upper lateral line, and representing the darkest area in the midlateral bar (the upper lateral line is in contact with the upper fifth of the round midlateral spot; midlateral bar progressively fades, and the midlateral spot becomes darker in all but small juvenile specimens) (Ref. 57436).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.00849 - 0.04084), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.3   ±0.5 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
