Population: The Dynamics of Change
Outlook on Agriculture, 1993Global population growth is generally considered to be one of the major driving forces of global change. Population changes, however, follow their own dynamics and can be influenced only marginally in the short run. This paper outlines the basic structure of these dynamics, including the important momentum of population growth.

Why are fishes more abundant in some areas than others? Why do abundances vary over time? What factors limit the sizes and productivity of populations? How do natural populations respond to harvesting, and where do we draw the line between sustainable and unsustainable fisheries?

Journal of Theoretical Biology, 1995
Population dynamics is analyzed by means of the power series expansion of a decay ratio F(P) with respect to the continuation probability, P, of survival. The truncation of the higher terms of the series yields the Verhulst equation as a first approximation. The approximation for higher age yields a simple exponential decay law of population, while the

The Population Dynamics and Conservation of Primate Populations
Conservation Biology, 1989Abstract: Primates are among the most threatened taxa, with more than half of all species in jeopardy. In this paper we develop population models to use the kind of data on wild primates that primatologists actually collect. Our survey of recentprimate journals suggests that the average field study uses 1.5 years of data from 50 animals The models are

Parasite population dynamics within a dynamic host population
Probability Theory and Related Fields, 1989We propose a stochastic process model for a parasite population living within a host population. The host population is described by an immigration-death process. The parasite population in one host is an immigration-birth-death-emigration process. The death of all parasites at the moment of death of their host is regarded as emigration.

Predicting when climate-driven phenotypic change affects population dynamics.
Ecology Letters, 2016Species' responses to climate change are variable and diverse, yet our understanding of how different responses (e.g. physiological, behavioural, demographic) relate and how they affect the parameters most relevant for conservation (e.g.

This paper proposes a conceptual revisiting of population dynamics to include heterogeneous behaviors of individuals, mutations, and selection. The first part of the paper focuses on the derivation of a general mathematical structure which permits to ...

11 The Dynamics of Population in Yugoslavia
Eastern European Economics, 1982A general review of population trends in Yugoslavia since the end of World War II is presented. Sections are included on natural population increase including fertility family planning and mortality; migration both internal and international; and changes in population characteristics.
