Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 22.5 - 27.5, mean 26.3 (based on 184 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03890 (0.01658 - 0.09129), b=2.88 (2.70 - 3.06), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High vulnerability (60 of 100) .
