Estimates based on models

Preferred temperature (Ref. 123201): 1.3 - 2.5, mean 1.8 °C (based on 23 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00126 (0.00058 - 0.00275), b=3.47 (3.29 - 3.65), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.3   ±0.54 se; based on food items.
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
