Estimates based on models
Preferred temperature (Ref. 115969
): 14.9 - 20.8, mean 17.5 °C (based on 298 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01585 (0.00685 - 0.03669), b=3.05 (2.84 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.0 ±0.00 se; based on food items.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2-4.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (33 of 100) .
