Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), based on all LWR estimates for this body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.2 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): .
Vulnerability (Ref.
59153): Low vulnerability (10 of 100) .
