Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 23.6 - 29.1, mean 27.7 (based on 216 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00151 (0.00061 - 0.00373), b=2.91 (2.70 - 3.12), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.8   ±0.6 se; Based on size and trophs of closest relatives Resilience (Ref. 69278 ):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.). Vulnerability (Ref. 59153 ):  Low to moderate vulnerability (32 of 100) .
