Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 21.5 - 28, mean 26.2 (based on 235 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03548 (0.01693 - 0.07438), b=2.81 (2.62 - 3.00), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 2.4 ±0.1 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Fec assumed to be > 10,000).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (28 of 100) .
