Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00397 - 0.03168), b=2.97 (2.73 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Weerstandsvermogen (Ref.
