Estimates based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00294 - 0.01416), b=2.98 (2.78 - 3.18), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
Generation time: 6.9 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilienza (Ref. 120179):  Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  High vulnerability (65 of 100) .
