Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01238 (-0.10337 - 0.12813), b=3.22 (3.15 - 3.30), based on LWR estimates for species & family-BS (Ref.
93245).
Trophic Level (Ref.
69278): 3.6 ±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 (15 of 100) .
