Estimates based on models
Preferred temperature (Ref. 115969
): 17.5 - 23.5, mean 19.7 °C (based on 31 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00457 (0.00195 - 0.01073), b=3.17 (2.96 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.1 se; based on size and trophs of closest relatives
Generation time: 0.3 ( 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 Fec < 1,000).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
