Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00472 - 0.01845), b=3.08 (2.92 - 3.24), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Resiliência (Ref.
120179): Médio, tempo mínimo de duplicação da população 1,4 - 4,4 anos (Preliminary K or Fecundity.).
