Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00424 - 0.01421), b=3.05 (2.88 - 3.22), based on LWR estimates for this species & Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.1 ±0.3 se; Based on diet studies.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Assuming Fec=10-100).
Vulnerability (Ref. 59153
