Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 13.3 - 25.3, mean 15.9 (based on 90 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00275 (0.00124 - 0.00609), b=3.25 (3.07 - 3.43), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.6   ±0.53 se; Based on food items. Resilience (Ref. 69278 ):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
