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=0.00796 (-0.23920 - 0.25513), b=2.93 (2.80 - 3.06), based on LWR estimates for this family-BS (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 (Assuming tmax>3).
Vulnerability (Ref. 59153):  Low vulnerability (23 of 100) .
Price category (Ref. 80766):   .
