Estimates of some properties based on models

Preferred temperature (Ref. 115969): 11.7 - 16.6, mean 14.2 (based on 82 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00390 - 0.02813), b=2.87 (2.64 - 3.10), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.48 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100) .
