Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00316 (0.00153 - 0.00654), b=3.11 (2.93 - 3.29), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.3 ±0.3 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (Annual Fec assumed to be <10).
Vulnerability (Ref. 59153
): Very high vulnerability (88 of 100) .
