Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00458 - 0.01093), b=3.10 (2.97 - 3.23), based on LWR estimates for species & Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.7 ±0.1 se; Based on diet studies.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (tm=1-3; Fec=72,000; tmax=27).
Vulnerability (Ref. 59153
): Moderate vulnerability (36 of 100) .
