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=0.00806 (-0.14916 - 0.16527), b=3.14 (3.05 - 3.23), based on LWR estimates for this genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.09; tmax=58).
Vulnerability (Ref. 59153):  High vulnerability (64 of 100) .
Price category (Ref. 80766):   Medium.
