Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00213 - 0.01294), b=3.10 (2.88 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (K=0.124; Tmax=10).
Vulnerability (Ref. 59153
): Moderate vulnerability (36 of 100) .
