Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00257 - 0.01023), b=3.06 (2.87 - 3.25), based on LWR estimates for species & Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.7 ±0.54 se; Based on food items.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (K=0.077; tmax=38; Fec = 458 (per batch)).
Vulnerability (Ref. 59153
): High to very high vulnerability (70 of 100) .
