Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5079 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00412 - 0.02789), b=3.04 (2.82 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.52 se; based on food items.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Fec= 50-200 eggs).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
