Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00468 - 0.01779), b=3.12 (2.96 - 3.28), based on LWR estimates for species & Subfamily-BS (Ref. 93245
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (55 of 100) .
