Estimates of some properties based on models

Preferred temperature (Ref. 115969): 6 - 12.3, mean 8.2 (based on 417 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 1.1250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00943 - 0.04220), b=2.91 (2.71 - 3.11), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.9 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Assuming tmax > 10).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (48 of 100) .
