Estimates of some properties based on models

Preferred temperature (Ref. 115969): 2.3 - 19.4, mean 10.1 (based on 114 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5313   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00437 (0.00196 - 0.00970), b=3.10 (2.90 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (tm=1; tmax=4).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (30 of 100) .
