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=0.00575 (0.00253 - 0.01308), b=3.10 (2.90 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.7   ±0.58 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 (23 of 100) .
