Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00219 (0.00107 - 0.00448), b=3.18 (3.01 - 3.35), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.9 ±0.61 se; Based on food items.
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (Fec=4).
Vulnerability (Ref. 59153
): High to very high vulnerability (74 of 100) .
