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=0.02179 (-0.08987 - 0.13345), b=2.98 (2.91 - 3.05), based on LWR estimates for species & genus-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.6 se; Based on diet studies.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (12 of 100) .
Price category (Ref. 80766):   Unknown.
