Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00617 - 0.01479), b=3.08 (2.96 - 3.20), based on LWR estimates for species & Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.1 ±0.3 se; Based on diet studies.
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (K=0.09-0.2; tmax=37; tm=3-7;).
Vulnerability (Ref. 59153
): High to very high vulnerability (70 of 100) .
