Estimates based on models
Preferred temperature (Ref. 115969
): -1.6 - 1.8, mean -0.6 °C (based on 1824 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00339 (0.00127 - 0.00906), b=3.07 (2.84 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.5 se; based on diet studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2-4;Fec<2000).
Vulnerability (Ref. 59153
): Low vulnerability (19 of 100) .
