Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00097 - 0.00495), b=3.17 (2.98 - 3.36), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.49 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  High vulnerability (64 of 100) .
Price category (Ref. 80766):   Low.
