Estimates based on models

Preferred temperature (Ref. 123201): 8.8 - 19, mean 13 °C (based on 406 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00205 - 0.01282), b=3.00 (2.79 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.4   ±0.45 se; based on food items.
Résilience (Ref. 120179):  Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).
