Estimates based on models

Preferred temperature (Ref. 115969 ): 2.4 - 10.4, mean 6.8 °C (based on 1057 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01622 (0.00649 - 0.04054), b=3.06 (2.84 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.4   ±0.2 se; based on diet studies. Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3). Vulnerability (Ref. 59153 ):  Low vulnerability (16 of 100) .
