Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.8125   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00406 - 0.02827), b=3.03 (2.81 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.3   ±0.5 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):  High to very high vulnerability (74 of 100) .
