Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00683 - 0.03057), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
