Estimates based on models
Preferred temperature (Ref. 115969): 1 - 7.5, mean 3.7 °C (based on 619 cells).
Phylogenetic diversity index (Ref. 82805): PD50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00318 - 0.00827), b=3.12 (2.98 - 3.26), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278): 3.3 ±0.1 se; based on diet studies.
Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (tm=3-6; tmax=27).
Vulnerability (Ref. 59153): High vulnerability (65 of 100) .
