Estimates based on models
Preferred temperature (Ref. 115969
): 24.7 - 28.9, mean 27.7 °C (based on 392 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02188 (0.01063 - 0.04504), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.1 se; based on diet studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
