Estimates based on models
Preferred temperature (Ref. 115969
): 1 - 7.5, mean 4.7 °C (based on 336 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
Generation time: 12.6 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (K=0.09(?); tm=5.1-8.4; tmax=105; Fec=19,815).
Vulnerability (Ref. 59153
): High to very high vulnerability (69 of 100) .
