Estimates based on models
Preferred temperature (Ref. 115969
): 18.5 - 25.4, mean 22.8 °C (based on 98 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01479 (0.00690 - 0.03171), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.7 ±0.5 se; based on size and trophs of closest relatives
Generation time: 3.7 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (35 of 100) .
