Estimates based on models

Preferred temperature (Ref. 123201): 0.7 - 13.9, mean 3.8 °C (based on 218 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.2500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00406 - 0.02827), b=3.02 (2.80 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.53 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=2-3; tmax=6; Fec=600-1,700).
