Phylogenetic diversity index (Ref. 82805
= 0.5029 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00813 (0.00473 - 0.01397), b=3.09 (2.93 - 3.25), based on LWR estimates for species & Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.0 ±0.2 se; Based on diet studies.
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>4).
Vulnerability (Ref. 59153
): Moderate vulnerability (37 of 100) .
