Estimates of some properties based on models
Preferred temperature (Ref. 115969): 3.5 - 5.4, mean 4.7 (based on 22 cells).
Phylogenetic diversity index (Ref. 82805): PD50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00249 - 0.01009), b=3.12 (2.95 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278): 3.5 ±0.37 se; Based on food items.
Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153): Moderate to high vulnerability (53 of 100) .
