Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00978 (-0.20103 - 0.22059), b=2.98 (2.86 - 3.10), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Assuming Fec<10).
Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100) .
Price category (Ref. 80766):   Low.
