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=0.00380 (0.00147 - 0.00985), b=3.11 (2.88 - 3.34), based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.0 ±0.32 se; Based on food items.
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (10 of 100) .
