Estimates based on models
Preferred temperature (Ref.
123201): 4.7 - 18.2, mean 10.2 °C (based on 64 cells).
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5781 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00185 - 0.01077), b=3.13 (2.91 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.1 ±0.35 se; based on food items.
Generation time: 15.0 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Weerstandsvermogen (Ref.
120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (K=0.07-0.13; tmax=7(?)).
