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=0.01259 (0.00477 - 0.03322), b=3.04 (2.81 - 3.27), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.0   ±0.00 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=4; K=0.428; Tmax=25).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (33 of 100) .
Price category (Ref. 80766):   Medium.
