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 (0.00304 - 0.01252), b=2.88 (2.70 - 3.06), based on LWR estimates for species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (K=0.41-0.48; tmax=3).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (26 of 100) .
Price category (Ref. 80766):   Unknown.
