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
): 3.4 ±0.4 se; Based on diet studies.
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (K=0.18; tmax=57).
Prior r = 0.2, 2 SD range = 0.1 - 0.40, log(r) = -1.61, SD log(r) = 0.34, Based on: 6 K, 2 tmax, 1 Fec records
Vulnerability (Ref. 59153
): Moderate to high vulnerability (50 of 100) .
