Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00374 - 0.01935), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.36 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (tmax=2).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
