Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 10 - 13.1, mean 11.8 (based on 11 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00316 (0.00159 - 0.00631), b=3.12 (2.95 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.9   ±0.2 se; Based on size and trophs of closest relatives Resilience (Ref. 69278 ):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100). Vulnerability (Ref. 59153 ):  Low to moderate vulnerability (33 of 100) .
