Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (-0.16711 - 0.17489), b=3.12 (3.03 - 3.21), based on all LWR estimates for this BS (Ref.
93245).
Trophic Level (Ref.
69278): 3.2 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (10 of 100) .
