Estimates based on models
Preferred temperature (Ref.
123201): -1.4 - 1.3, mean 0.5 °C (based on 43 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00132 (0.00102 - 0.00170), b=3.51 (3.44 - 3.58), in cm total length, based on LWR estimates for this species (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.62 se; based on food items.
Generation time: 5.8 ( 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. (Assuming tm<5).
