Estimates based on models
Preferred temperature (Ref. 123201
): -1 - 7.1, mean 0.8 °C (based on 559 cells).
Phylogenetic diversity index (Ref. 82804
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00774 - 0.05639), b=3.02 (2.79 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.40 se; based on food items.
Resilience (Ref. 120179
