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=0.01023 (0.00529 - 0.01978), b=3.07 (2.91 - 3.23), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.4 se; Based on diet studies.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (K=0.18; tmax=57).
Prior r = 0.2, 2 SD range = 0.1 - 0.40, log(r) = -1.61, SD log(r) = 0.34, Based on: 6 K, 2 tmax, 1 Fec records
Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100) .
