Estimates based on models
Preferred temperature (Ref. 115969
): 2.4 - 3.4, mean 2.8 °C (based on 108 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7539 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00174 (0.00083 - 0.00364), b=3.16 (2.96 - 3.36), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming Fec <100).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (50 of 100) .
