Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00046 (0.00020 - 0.00105), b=3.12 (2.92 - 3.32), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.1   ±0.7 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).
Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100) .
