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=0.01409 (-0.10742 - 0.13559), b=2.99 (2.91 - 3.06), based on LWR estimates for species & family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  2.7   ±0.30 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 (14 of 100) .
Price category (Ref. 80766):   Unknown.
