Estimates based on models
Preferred temperature (Ref. 115969
): -1.8 - 1.1, mean -0.9 °C (based on 733 cells).
Phylogenetic diversity index (Ref. 82805
= 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00166 (0.00070 - 0.00391), b=3.43 (3.23 - 3.63), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.9 ±0.62 se; based on food items.
Generation time: 12.2 ( 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 (Fec = 6,200).
Vulnerability (Ref. 59153
): High vulnerability (59 of 100) .
