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=0.01000 (0.00522 - 0.01915), b=3.07 (2.90 - 3.24), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (K=0.09(?); tm=5.1-8.4; tmax=105; Fec=19,815).
Prior r = 0.18, 2 SD range = 0.07 - 0.47, log(r) = -1.71, SD log(r) = 0.47, Based on: 1 M, 1 K, 7 tgen, 2 tmax, 3 Fec records
Vulnerability (Ref. 59153):  High to very high vulnerability (69 of 100) .
Price category (Ref. 80766):   Medium.
