Estimates based on models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.01199 - 0.01825), b=3.05 (3.01 - 3.09), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278): 3.0 ±0.3 se; based on diet studies.
Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153): Low vulnerability (20 of 100) .
