Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278):  2.2   ±0.0 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (39 of 100) .
Price category (Ref. 80766):   High.
