Estimates based on models

Preferred temperature (Ref. 115969): 4.7 - 12.2, mean 7.9 (based on 759 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00247 - 0.01279), b=3.09 (2.90 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.3 se; Based on size and trophs of closest relatives
Generation time: 1.4 ( na - na) years. Estimated as median LN(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=3.7; tm=1.4; K=0.8).
Vulnerability (Ref. 59153):  Low vulnerability (17 of 100) .
