Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00288 (0.00127 - 0.00656), b=3.21 (3.03 - 3.39), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 3.7 ±0.5 se; Based on size and trophs of closest relatives
Resiliencia (Ref.
69278): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).
Vulnerability (Ref.
