Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805
= 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00331 (0.00155 - 0.00706), b=3.10 (2.91 - 3.29), based on LWR estimates for this Subfamily-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
): Moderate vulnerability (38 of 100) .
