Estimates based on models
Preferred temperature (Ref. 115969
): 6.8 - 16.7, mean 11.6 °C (based on 217 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5157 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.37 se; based on food items.
Generation time: 4.1 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=4).
Vulnerability (Ref. 59153
