Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 12.4 - 21.7, mean 16.4 (based on 110 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5002 [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
): 3.5 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Assuming Fec < 100).
Vulnerability (Ref. 59153
): Low vulnerability (25 of 100) .
