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=0.01072 (0.00781 - 0.01471), b=3.05 (2.96 - 3.14), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.53 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.11; tmax=11).
Vulnerability (Ref. 59153):  High vulnerability (60 of 100) .
