Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01288 (0.00617 - 0.02688), b=3.03 (2.86 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.8   ±0.34 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100) .
Price category (Ref. 80766):   Very high.
