Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01187 (-0.20789 - 0.23163), b=3.04 (2.92 - 3.16), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278): 3.4 ±0.4 se; Based on diet studies.
Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Fec = 66).
Vulnerability (Ref. 59153): Moderate to high vulnerability (53 of 100) .
