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=0.00347 (0.00155 - 0.00778), b=3.10 (2.90 - 3.30), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.2 ±0.5 se; Based on diet studies.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Prior r = 0.08, 2 SD range = 0.01 - 0.54, log(r) = -2.53, SD log(r) = 0.94, Based on: 1 K, 1 tmax, 1 Fec records
Vulnerability (Ref. 59153
): High to very high vulnerability (69 of 100) .
