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=0.01000 (0.00524 - 0.01907), b=3.07 (2.90 - 3.24), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.7 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (tmax=87; tm=10).
Prior r = 0.16, 2 SD range = 0.04 - 0.63, log(r) = -1.83, SD log(r) = 0.68, Based on: 6 tgen, 1 tmax, 1 Fec records
Vulnerability (Ref. 59153
