Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00232 - 0.01084), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.0 ±0.43 se; based on food items.
回复力 (Ref.
120179): 高度, 族群倍增时间少于 15个月 (tm=1; tmax=3).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
