Estimates based on models
Preferred temperature (Ref.
123201): -1.3 - 1.2, mean -0.1 °C (based on 18 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00646 (0.00293 - 0.01422), b=3.17 (2.97 - 3.37), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Mức dinh dưỡng (Ref.
69278): 3.4 ±0.1 se; based on diet studies.
Generation time: 4.5 ( na - na) years. Estimated as median ln(3)/K based on 2
