Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02818 (0.01692 - 0.04693), b=2.83 (2.68 - 2.98), based on LWR estimates for species & Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.0 ±0.0 se; Based on diet studies.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Fec assumed to be > 10,000).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (26 of 100) .
