Estimates based on models
Preferred temperature (Ref. 115969
): 9.7 - 11.9, mean 9.9 °C (based on 5 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01175 (0.00690 - 0.02001), b=3.01 (2.87 - 3.15), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (tmax=18).
Vulnerability (Ref. 59153
): High to very high vulnerability (67 of 100) .
