Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00523 - 0.02406), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 2.5 ±0.19 se; based on food items.
Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (K=0.65; tm=1; tmax=4).
Fishing Vulnerability (Ref.
59153): Low vulnerability (19 of 100).
