Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02089 (0.00997 - 0.04380), b=2.92 (2.74 - 3.10), based on LWR estimates for this Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.8 ±0.35 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (15 of 100) .
