Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00328 - 0.01924), b=3.01 (2.80 - 3.22), based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.3 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months ().
Vulnerability (Ref.
59153): Low vulnerability (10 of 100) .
