    "abstract": "Most population models assume that individuals within a given population are\nidentical, that is, the fundamental role of variation is ignored. Here we\ndevelop a general approach to modeling heterogeneous populations with discrete\nevolutionary time step. The theory is applied to population dynamics of natural\nrotifer populations. We show that under particular conditions the behavior of\nthe inhomogeneous model possesses complex transition regimes, which depends\nboth on the mean and the variance of the initial parameter distribution and the\nfinal state of the population depends on the least possible value from the\ndomain of the parameter. The question of persistence of the population is\ndiscussed.",
