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=0.01230 (0.00544 - 0.02785), b=3.00 (2.82 - 3.18), based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (11 of 100) .
Price category (Ref. 80766):   Unknown.
