Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00912 (0.00463 - 0.01795), b=3.08 (2.91 - 3.25), based on LWR estimates for this Family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.1 ±0.2 se; Based on diet studies.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (tm=0.75; tmax=3).
Vulnerability (Ref. 59153
): Low vulnerability (15 of 100) .
