Estimates based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00318 - 0.01574), b=3.08 (2.89 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Generation time: 5.5 ( na - na) years. Estimated as median LN(3)/K based on 1
growth studies.
Widerstandsfähigkeit (Ref.
120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (K=0.2).
Verwundbarkeit (Ref.
