Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (-0.30300 - 0.32300), b=3.04 (2.92 - 3.16), based on all LWR estimates for this BS (Ref.
93245).
Trophic Level (Ref.
69278): 3.8 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).
Vulnerability (Ref.
59153): Moderate to high vulnerability (45 of 100) .
Price category (Ref.
