Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01284 (-0.01884 - 0.04451), b=3.03 (3.01 - 3.05), based on LWR estimates for this species (Ref.
93245).
Trophic Level (Ref.
69278): 3.3 ±0.4 se; Based on diet studies.
Resilience (Ref.
69278): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.3; Fec=36,000; tm=4).
Vulnerability (Ref.
59153): Moderate to high vulnerability (52 of 100) .
