Estimates of some properties based on models

Preferred temperature (Ref. 115969): 20.6 - 27.7, mean 23.3 (based on 42 cells).

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00977 (0.00393 - 0.02432), b=3.08 (2.86 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.47 se; Based on food items.

Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).

Vulnerability (Ref. 59153): Low vulnerability (25 of 100) .
