Biologie     Verklarende woordenlijst (bv. epibenthic)

Occurs in ponds (Ref. 11229). Inhabits shallow, densely vegetated microhabitats in small streams or along the banks of larger rivers (Ref. 106564). Feeds mostly on fishes (Ref. 598). Two rodents (Sigmodontinae) were found in the stomachs of two individuals in different rivers located in the southern Brazilian Atlantic Rain Forest, in March and November 2010. These represent the first records of this species feeding on mammals (Ref. 106564).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00515 - 0.01226), b=3.02 (2.90 - 3.14), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  4.2   ±0.73 se; based on food items.
Generation time: 1.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Weerstandsvermogen (Ref. 120179):  Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
Nutrients (Ref. 124155):  Calcium = 68.1 [18.5, 168.3] mg/100g; Iron = 1.55 [0.81, 3.65] mg/100g; Protein = 19.2 [17.2, 21.4] %; Omega3 = 0.843 [0.346, 2.269] g/100g; Selenium = 33.5 [13.3, 74.1] μg/100g; VitaminA = 46.9 [15.2, 140.5] μg/100g; Zinc = 0.957 [0.665, 1.374] mg/100g (wet weight);
