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=0.00324 (0.00157 - 0.00666), b=3.11 (2.93 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.7   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (28 of 100) .
