Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00363 (0.00164 - 0.00803), b=3.07 (2.87 - 3.27), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.2   ±0.73 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (27 of 100) .
Price category (Ref. 80766):   Unknown.
