Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01642 (-0.17853 - 0.21137), b=3.01 (2.90 - 3.12), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278): 2.0 ±0.00 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 to moderate vulnerability (35 of 100) .
