Estimates based on models
Preferred temperature (Ref. 115969
): 24.4 - 28, mean 27.3 °C (based on 211 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00050 (0.00025 - 0.00101), b=3.26 (3.09 - 3.43), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.5 ±0.56 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 (61 of 100) .
