Estimates based on models
Preferred temperature (Ref. 115969
): 14.7 - 21, mean 19.2 °C (based on 25 cells).
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.0 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (50 of 100) .
