Estimates based on models
Preferred temperature (Ref. 115969
): 1.8 - 18.1, mean 11.5 °C (based on 404 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
): 3.6 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2-4).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (25 of 100) .
