Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00841 (-0.08526 - 0.10207), b=3.04 (2.98 - 3.10), based on LWR estimates for species & family-BS (Ref. 93245).
Trophic Level (Ref. 69278): 3.8 ±0.6 se; Based on diet studies.
Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153): Low vulnerability (18 of 100) .
