Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00693 - 0.01903), b=3.01 (2.86 - 3.16), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 4.5 ±0.3 se; based on diet studies.
Generation time: 7.0 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Resilienza (Ref.
