Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00000 (0.00000 - 0.00000), b=0.00 (0.00 - 0.00), based on (Ref. 93245).
Trophic Level (Ref. 69278): 3.1 ±0.2 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 (14 of 100) .
