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=0.01009 (-0.09948 - 0.11966), b=3.02 (2.95 - 3.10), based on LWR estimates for species & genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.19; tmax=41).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100) .
Price category (Ref. 80766):   Very high.
