Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00107 (-0.12000 - 0.12214), b=3.19 (3.11 - 3.27), based on LWR estimates for species & family-BS (Ref. 93245).
Trophic Level (Ref. 69278): 3.7 ±0.6 se; Based on diet studies.
Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153): Moderate to high vulnerability (48 of 100) .
