Estimates based on models
Preferred temperature (Ref. 115969
): 0.9 - 19.3, mean 12.9 °C (based on 181 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.9 ±0.53 se; based on food items.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).
Vulnerability (Ref. 59153
): Moderate vulnerability (43 of 100) .
