Estimates based on models
Preferred temperature (Ref. 115969
): 3.8 - 12.1, mean 6.2 °C (based on 127 cells).
Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00268 - 0.01126), b=2.90 (2.72 - 3.08), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.42 se; based on food items.
Generation time: 4.6 ( 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 (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
