Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01380 (0.00629 - 0.03027), b=3.03 (2.83 - 3.23), based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (39 of 100) .
Price category (Ref. 80766):   Unknown.
