Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00166 (0.00085 - 0.00325), b=3.36 (3.18 - 3.54), based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.54 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=4; Fec = 2,770).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100) .
Price category (Ref. 80766):   Very high.
