Estimates based on models
Preferred temperature (Ref. 115969
): 23.8 - 28.2, mean 27.2 °C (based on 459 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00361 - 0.01750), b=2.80 (2.62 - 2.98), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.37 se; based on food items.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
