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=0.02154 (-0.12735 - 0.17043), b=3.03697 (2.94844 - 3.12551), based on LWR estimates for species & family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.59 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (24 of 100) .
Price category (Ref. 80766):   Medium.
