Estimates of some properties based on models

Preferred temperature (Ref. 115969): 12.1 - 23, mean 15.2 (based on 93 cells; Ref. 115970).
Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00341 - 0.01765), b=2.82 (2.63 - 3.01), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100) .
