Estimates based on models
Preferred temperature (Ref. 115969
): 15.6 - 26.5, mean 23.5 °C (based on 180 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00324 (0.00142 - 0.00736), b=3.17 (2.99 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.37 se; based on food items.
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (Tm=9-26; Tmax=33).
Vulnerability (Ref. 59153
): Very high vulnerability (79 of 100) .
