Estimates based on models
Preferred temperature (Ref. 115969
): 2.1 - 13.9, mean 6.7 °C (based on 1605 cells).
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00468 (0.00219 - 0.00998), b=3.17 (2.98 - 3.36), 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 size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (12 of 100) .
