Estimates based on models
Preferred temperature (Ref. 115969
): 25.3 - 29.3, mean 28.7 °C (based on 1113 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00332 - 0.01511), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
