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=0.00224 (0.00111 - 0.00453), b=3.18 (3.01 - 3.35), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.7   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Fec=7).
Vulnerability (Ref. 59153):  High vulnerability (64 of 100) .
Price category (Ref. 80766):   Medium.
