Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (-0.30300 - 0.32300), b=3.04000 (2.92100 - 3.15900), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.60 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  High vulnerability (63 of 100) .
Price category (Ref. 80766):   Unknown.
