Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trofisch niveau (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Generation time: 3.1 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
Weerstandsvermogen (Ref.
