Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00977 (0.00501 - 0.01905), b=3.13 (2.97 - 3.29), based on LWR estimates for species & Subfamily-body shape (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 (K=0.19-0.33).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100) .
Price category (Ref. 80766):   Unknown.
