Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00196 - 0.00927), b=3.08 (2.89 - 3.27), based on LWR estimates for this Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.5 ±0.80 se; Based on food items.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10; tm=3).
Vulnerability (Ref. 59153
): High to very high vulnerability (74 of 100) .
