Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100) .
Price category (Ref. 80766):   Medium.
