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=0.01023 (0.00452 - 0.02316), b=3.06 (2.86 - 3.26), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.5 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.30; tmax=11; tm=2.5).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (35 of 100) .
Price category (Ref. 80766):   Medium.
