Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00517 - 0.01933), b=3.09 (2.93 - 3.25), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 2.7 ±0.22 se; based on food items.

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (tm = 0.13; tmax = 0.33; Batch Fec = 1-7;).

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

Prijsklasse (Ref. 80766): Unknown.

Heterandria formosa (Girard, 1859)
