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=0.01260 (0.00676 - 0.02349), b=3.06 (2.90 - 3.22), based on LWR estimates for species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.45 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=7).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (51 of 100) .
Price category (Ref. 80766):   Very high.
