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=0.01349 (0.00591 - 0.03081), b=3.14 (2.95 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 2.6 ±0.1 se; based on size and trophs of closest relatives
Resiliencia (Ref.
120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Assuming tm<1).
Fishing Vulnerability (Ref.
