Estimates based on models
Preferred temperature (Ref. 115969
): 4.5 - 9.5, mean 5.9 °C (based on 139 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00164 - 0.00733), b=3.19 (3.00 - 3.38), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (44 of 100) .
