Biologie     Glossaire (ex. epibenthic)

A riverine species collected some distance up a low-gradient swampy tributary of the Rio Negro (the Rio Jufari), Brazil and in the main river, in both cases the water generally darkly tinted, acid (pH 4-5) and low in dissolved ions. Feeds on dipteran larvae and pupae; also cladocerans. Males mature at 1.43-1.62 cm SL; females at 1.59-1.82 cm. Ovarian eggs are creamy or pale orange. A female of 1.73 cm had 20 eggs in the single ovary in January.

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00253 - 0.01141), b=3.13 (2.96 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.2   ±0.35 se; based on food items.
Résilience (Ref. 120179):  Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
