Estimates based on models
Preferred temperature (Ref.
123201): 12.8 - 19, mean 16.7 °C (based on 63 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00495 - 0.02022), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.4 ±0.48 se; based on food items.
Generation time: 4.4 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilienza (Ref.
