Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00310 (-0.18805 - 0.19424), b=3.14177 (3.03610 - 3.24744), based on LWR estimates for this family-BS (Ref.
93245).
Trophic Level (Ref.
69278): 3.7 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref.
69278): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref.
59153): Moderate to high vulnerability (48 of 100) .
