Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00400 - 0.02738), b=3.01 (2.79 - 3.23), based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.4 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Vulnerability (Ref.
59153): Low vulnerability (25 of 100) .
