Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00744 - 0.00929), b=3.09 (3.06 - 3.12), in cm Total Length, based on LWR estimates for this species (Ref.
93245).
Trophic Level (Ref.
69278): 3.5 ±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 (25 of 100) .
