The paper is aimed at the methodological development of ecological monitoring in discrete-
time dynamic models. In earlier papers, in the framework of continuous-time models, we …

This paper is a review of recent developments of a research line proposed on the turn of the
decades, 1980s to 1990s. The main results concern basic qualitative properties of nonlinear …

The problem of the possibility of recovering the time-dependent state of a whole population
system from the observation of certain components has been studied in earlier publications …

In the paper observability problems are considered in basic dynamic evolutionary models for
sexual and asexual populations. Observability means that from the (partial) knowledge of …

Abstract For Lotka-Volterra population systems, a general model of state monitoring is
presented. The model includes time-dependent environmental effects or direct human …

In the paper a single-locus sexual population is considered, where the phenotypic selection
process is described by an evolutionary game. First, in order to recover the genetic process …

In the paper simple trophic chains of the type resource–producer–primary consumer are
considered. For an analysis of the dynamic state monitoring of this system, the concept of …

The goal of this work is the monitoring of the corresponding species in a class of predator–
prey systems, this issue is important from the ecology point of view to analyze the population …

The paper is an update of two earlier review papers concerning the application of the
methodology of mathematical systems theory to population ecology, a research line initiated …

In this paper we shortly discuss the problem of the equilibrium in the well-known Fisher type
selection-mutation model, also providing a formula for particular three-allele models. The …
