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=0.00355 (0.00212 - 0.00594), b=3.10 (2.95 - 3.25), based on LWR estimates for species & (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.50 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (32 of 100) .
Price category (Ref. 80766):   Medium.
