Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00710 - 0.01069), b=3.01 (2.95 - 3.07), in cm Total Length, based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.13; tmax=36; Fec=32).
Prior r = 0.18, 2 SD range = 0.05 - 0.65, log(r) = -1.71, SD log(r) = 0.64, Based on: 2 K, 1 tmax, 2 Fec records
Vulnerability (Ref. 59153):  High vulnerability (62 of 100) .
Price category (Ref. 80766):   Medium.
