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=0.00617 (0.00352 - 0.01079), b=3.21 (3.06 - 3.36), based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.3 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (tm=3; k=0.22).
Prior r = 0.47, 2 SD range = 0.26 - 0.84, log(r) = -0.76, SD log(r) = 0.29, Based on: 3 K, 1 tgen, 1 tmax, 1 Fec records
Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100) .
