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=-2.00000 (nan - nan), b=3.04 (2.81 - 3.27), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  .
Vulnerability (Ref. 59153):  Low to moderate vulnerability (31 of 100) .
Price category (Ref. 80766):   Unknown.
