Preferred temperature (Ref. 115969
): 10.9 - 14.9, mean 12.2 °C (based on 13 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00224 (0.00099 - 0.00507), b=3.16 (2.97 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.1 ±0.61 se; based on food items.
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): High vulnerability (57 of 100) .
