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=0.00301 (-0.14572 - 0.15174), b=3.15 (3.06 - 3.24), based on LWR estimates for this family-BS (Ref.
93245).
Trophic Level (Ref.
69278): 4.0 ±0.6 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): Low to moderate vulnerability (34 of 100) .
