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=0.03548 (0.02249 - 0.05597), b=2.84 (2.71 - 2.97), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Resilience (Ref. 69278):  .
Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100) .
