Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01549 (0.01028 - 0.02333), b=2.99 (2.87 - 3.11), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 2.2 ±0.1 se; based on size and trophs of closest relatives
Generation time: 1.9 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Weerstandsvermogen (Ref.
120179): Gemiddeld, minimale populatieverdubbelingstijd 1,4-4,4 jaar (tm=2-3; tmax=5).
