Estimates based on models
Phylogenetic diversity index (参照
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.01108 - 0.01568), b=3.07 (3.03 - 3.11), in cm total length, based on LWR estimates for this species (Ref.
93245).
栄養段階 (参照
69278): 3.0 ±0.3 se; based on diet studies.
Generation time: 2.0 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回復力 (参照
120179): 高い, １５か月以下の倍増期間の最小個体群 (Preliminary K or Fecundity.).
