Estimates based on models
Preferred temperature (Ref. 115969
): 4.1 - 8.6, mean 5.8 °C (based on 200 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00479 - 0.02087), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (K=0.07-0.10; tmax=82).
Vulnerability (Ref. 59153
): High to very high vulnerability (68 of 100) .
