Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00100 (-0.04950 - 0.05151), b=3.45 (3.41 - 3.48), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.5 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.17-0.24; Fec = 7,358).
Vulnerability (Ref. 59153):  High vulnerability (56 of 100) .
Price category (Ref. 80766):   High.
