Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01380 (0.01007 - 0.01892), b=3.14 (3.05 - 3.23), in cm Total Length, based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  2.9   ±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 to moderate vulnerability (31 of 100) .
