Estimates based on models
Preferred temperature (Ref. 115969
): 4.3 - 7.6, mean 5.7 °C (based on 161 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
): 4.4 ±0.4 se; based on diet studies.
Generation time: 29.5 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179
): Very Low, minimum population doubling time more than 14 years (tm=12-15; tmax=118).
Vulnerability (Ref. 59153
): High to very high vulnerability (73 of 100) .
