Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): -1.1 - 2.9, mean 1.5 (based on 50 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00145 (0.00115 - 0.00182), b=3.42 (3.35 - 3.49), in cm Total Length, based on LWR estimates for this species (Ref. 93245 ). Trophic Level (Ref. 69278 ):  3.2   ±0.2 se; Based on diet studies. Resilience (Ref. 69278 ):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.13-0.39; tmax=13; tm=4; Fec=3,094). Prior r = 0.34, 2 SD range = 0.12 - 1.00, log(r) = -1.08, SD log(r) = 0.54, Based on: 5 K, 4 tgen, 27 Fec records Vulnerability (Ref. 59153 ):  Moderate vulnerability (35 of 100) .
