Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00303 (-0.16674 - 0.17279), b=3.12 (3.02 - 3.22), based on LWR estimates for this family-BS (Ref.
93245).
Trophic Level (Ref.
69278): 4.2 ±0.7 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): Low, minimum population doubling time 4.5 - 14 years (Fec=12).
Vulnerability (Ref.
59153): Moderate to high vulnerability (51 of 100) .
