Estimates based on models
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.9 ±0.63 se; based on food items.
回复力 (Ref.
