Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 23.7 - 24.6, mean 23.9 (based on 11 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00537 (0.00254 - 0.01136), b=3.09 (2.90 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  4.1   ±0.55 se; Based on food items. Resilience (Ref. 69278 ):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.). Vulnerability (Ref. 59153 ):  Low vulnerability (22 of 100) .
