Estimates of some properties based on models

Preferred temperature (Ref. 115969): 1.1 - 17, mean 12 (based on 88 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5029   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00270 - 0.01345), b=3.08 (2.88 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.2   ±0.71 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2-4).
