Estimates based on models

Preferred temperature (Ref. 115969): 3.5 - 5.4, mean 4.7 °C (based on 22 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00272 - 0.01111), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.37 se; based on food items.
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).
Verwundbarkeit (Ref. 59153):  High vulnerability (58 of 100) .
