Most species are structured and influenced by processes that either increased or reduced gene flow between populations. However, most population genetic inference methods ignore population structure and reconstruct a history characterized by population size changes under the assumption that species behave as panmictic units. This is potentially problematic since population structure can generat...

Much research has been carried out to understand the emergence of cooperation in simulated social networks of competing individuals. Such research typically implements a population as a single connected network. Here we adopt a more realistic premise; namely that populations consist of multiple networks, whose members migrate from one to another. Specifically, we isolate the key elements of the...

Neuhauser et al. (2003) and Whitham et al. (2003) clearly demonstrate the powerful insights that can be gained from examining the evolutionary process in an ecological context by combining community ecology and population genetics. These approaches show how organism interactions can influence rates and direction of evolution, and how genetic variation within populations can influence patterns o...

“Artificial societies” are constructed to examine L2-based creole development. ‘Virtual’ slaves and slave-owners interact based on socio-historical conditions. Linguistic transmissions and developments are tracked. This study takes no position on whether a theory of ‘imperfect L2 acquisition of the superstrate language’ can be viewed as final truth with respect to creole genesis. However, a Com...

This paper studies the long run spatial development of U.S. counties and metro areas between 1790 and 2000. The often-documented orthogonality between population growth and initial population size — Gibrat’s law — only emerges recently. Between 1790 and 1940 population growth tends to be decreasing with county population, except among the largest counties, for which population growth is slightl...

human history. The first cities were built on the plains of Mesopotamia near the Tigris and Euphrates rivers between the years 4000 and 3000 BC. The first city to reach a population of one million was Rome, in about 5 BC. Not until about 1800 AD had another city, London, reached the one million mark. Urban populations grew rapidly throughout the 19th century, fueled more by migration from rural...

This paper proposes a non-phenomenological model of population growth that is based on the interactions between the individuals that compose the system. It is assumed that the individuals interact cooperatively and competitively. As a consequence of this interaction, it is shown that some well-known phenomenological population growth models (such as the Malthus, Verhulst, Gompertz, Richards, Vo...

Diversity is a fundamental property of all evolving systems. This thesis examines spatial and temporal patterns of diversity. The systems I will study consist of a population of individuals, each with a potentially unique state, together with a dynamics consisting of copying or reproduction of individual states with small modifications to them (innovations). I show that properties of diversity ...

This paper introduces a collection of related research studies on the anthropological demography of Europe. Anthropological demography is a specialty within demography that uses anthropological theory and methods to provide a better understanding of demographic phenomena in current and past populations. Its genesis and ongoing growth lies at the intersection of demography and socio-cultural ant...

The emergence and transmission of resistance to antimalarial treatments continue to hamper malaria elimination efforts. A scoping review was undertaken regarding the impact of antimalarial treatment in the human population on the emergence and transmission of Plasmodium falciparum resistance, to (i) describe the use of mathematical models used to explore this relationship; (ii) discuss model fi...
