Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00388 - 0.02826), b=2.87 (2.64 - 3.10), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.3 ±0.31 se; Based on food items.
Resilienza (Ref.
69278): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Assuming fecundity<100).
Vulnerability (Ref.
59153): Low vulnerability (15 of 100) .
