Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=3).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Unknown.
