Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01020 (0.00461 - 0.02257), b=3.07 (2.87 - 3.27), based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  2.8   ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (47 of 100) .
Price category (Ref. 80766):   Unknown.
