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=0.00316 (0.00152 - 0.00660), b=3.10 (2.92 - 3.28), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.9   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (35 of 100) .
