Estimates based on models
Preferred temperature (Ref.
123201): -1.9 - 1.6, mean -0.7 °C (based on 751 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5059 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00437 (0.00168 - 0.01136), b=3.11 (2.89 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.4 ±0.4 se; based on diet studies.
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回复力 (Ref.
