Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5664   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00366 (-0.21292 - 0.22024), b=3.11 (3.00 - 3.23), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  4.1   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Fec is assumed to be <10).
Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100) .
Price category (Ref. 80766):   Unknown.
