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=0.01255 (-0.11550 - 0.14059), b=3.05 (2.98 - 3.13), based on LWR estimates for species & genus-BS (Ref. 93245).
Trophic Level (Ref. 69278): 2.0 ±0.00 se; Based on food items.
Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153): Moderate vulnerability (42 of 100) .
