Estimates based on models
Preferred temperature (Ref. 115969
): 24.2 - 28.8, mean 27.6 °C (based on 776 cells).
Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02399 (0.01795 - 0.03206), b=2.89 (2.80 - 2.98), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 4.2 ±0.5 se; based on size and trophs of closest relatives
Generation time: 8.1 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (tmax=26; k=0.13).
Vulnerability (Ref. 59153
): High vulnerability (57 of 100) .
