Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01514 (0.00488 - 0.04699), b=3.03 (2.78 - 3.28), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.9 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (Fec assumed to be <10).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (51 of 100) .
