Estimates based on models
Preferred temperature (Ref.
123201): -1.8 - 0.9, mean -0.9 °C (based on 408 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00085 (0.00054 - 0.00133), b=3.45 (3.32 - 3.58), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.53 se; based on food items.
Resilience (Ref.
