We study the mathematical properties of the quasi-dynamic ordinary differential equations defined empirically in Chen et al. (2019). In particular, we show how the allometric scaling mentioned in that work emerges naturally from the generalized Lotka–Volterra model under the quasi-dynamic ordinary differential equations paradigm. We then define and study the proportional quasi-dynamic ordinary differential equations and discuss the relationship of this equation system to both the classical and discrete time replicator dynamics. We prove asymptotic properties of these systems for large and small populations and show that there exist populations for which the proportion of the population varies cyclically as a function of total logarithmic population size.
