Estimates of some properties based on models

Preferred temperature (Ref. 115969): 25.8 - 29.3, mean 28.7 (based on 1775 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 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).
Resiliens (Ref. 69278):  Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (22 of 100) .
