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=0.01479 (0.01125 - 0.01945), b=2.97 (2.90 - 3.04), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  2.0   ±0.0 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.22, tm=1-2).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (32 of 100) .
Price category (Ref. 80766):   High.
