Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 25.4 - 28.3, mean 27.4 (based on 193 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01905 (0.00889 - 0.04085), b=2.95 (2.78 - 3.12), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
