Estimates based on models

Preferred temperature (Ref. 123201): 19.2 - 28.9, mean 25.8 °C (based on 76 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02630 (0.01678 - 0.04123), b=2.85 (2.72 - 2.98), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.37 se; based on food items.
Generation time: 6.5 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
