Estimates of some properties based on models

Preferred temperature (Ref. 115969): 19.5 - 27.2, mean 24.5 (based on 115 cells; Ref. 115970).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01349 (0.00635 - 0.02866), b=3.02 (2.85 - 3.19), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.7   ±0.2 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (36 of 100) .
