Estimates based on models
Preferred temperature (Ref. 115969
): 17 - 23.4, mean 20.3 °C (based on 63 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5313 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02239 (0.00945 - 0.05301), b=2.93 (2.72 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.8 ±0.5 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 vulnerability (18 of 100) .
