Estimates of some properties based on models

Preferred temperature (Ref. 115969): 2.2 - 6.5, mean 4.6 (based on 172 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00741 (0.00629 - 0.00874), b=3.06 (3.02 - 3.10), in cm Total Length, based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  4.2   ±0.3 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (tmax=23; K=.06-0.09; tm=5-7; Fec=250,000).
Prior r = 0.32, 2 SD range = 0.18 - 0.57, log(r) = -1.14, SD log(r) = 0.29, Based on: 2 K, 4 tgen, 1 tmax, 2 Fec records
Vulnerability (Ref. 59153):  High vulnerability (64 of 100) .
Price category (Ref. 80766):   Low.
