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=0.00537 (0.00330 - 0.00874), b=3.26 (3.12 - 3.40), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.1 ±0.63 se; Based on food items.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (K=0.10).
Prior r = 0.41, 2 SD range = 0.24 - 0.70, log(r) = -0.89, SD log(r) = 0.27, Based on: 2 K, 4 tgen, 1 tmax, 2 Fec records
