Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01660 (0.00760 - 0.03623), b=2.90 (2.71 - 3.09), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 2.9 ±0.4 se; Based on size and trophs of closest relatives
Resiliens (Ref.
69278): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
