Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.00842 - 0.04514), b=3.03 (2.82 - 3.24), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.53 se; Based on food items.
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (tm=2.5; tmax=10).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (34 of 100) .
