Estimates based on models
Preferred temperature (Ref. 115969
): 24 - 27.9, mean 27.2 °C (based on 10 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00048 (0.00026 - 0.00087), b=3.28 (3.13 - 3.43), in cm total length, based on LWR estimates for this 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
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (36 of 100) .
