Estimates based on models
Preferred temperature (Ref. 115969
): 2.4 - 6.5, mean 3.7 °C (based on 2178 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
