Estimates based on models
Preferred temperature (Ref. 115969
): 0 - 1.6, mean 1.2 °C (based on 6 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00320 - 0.01497), b=3.17 (2.99 - 3.35), 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
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Fec = 5,610-12,900;).
Vulnerability (Ref. 59153
