Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5781 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00269 (0.00115 - 0.00629), b=3.24 (3.04 - 3.44), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 4.0 ±0.66 se; based on food items.
Resilience (Ref.
