Discreteness Effects in Population Dynamics [PDF]
Journal of Physics A: Mathematical and Theoretical, 2016 We analyse numerically the effects of small population size in the initial transient regime of a simple example population dynamics. These effects play an important role for the numerical determination of large deviation functions of additive observables

Multigame Effect in Finite Populations Induces Strategy Linkage Between Two Games [PDF]
arXiv, 2013 Evolutionary game dynamics with two 2-strategy games in a finite population has been investigated in this study. Traditionally, frequency-dependent evolutionary dynamics are modeled by deterministic replicator dynamics under the assumption that the population size is infinite. However, in reality, population sizes are finite.

SPATIAL POPULATION DYNAMICS [PDF]
Papers in Regional Science, 1976 This paper examines the relationships between natural increase (births minus deaths) and net migration (in-migrants minus out-migrants) in regional populations and identifies and clarifies some of the fundamental population dynamics involved. First the authors consider several well-defined regularities of fertility mortality and migration schedules ...

Population dynamics at high Reynolds number [PDF]
, 2010 We study the statistical properties of population dynamics evolving in a realistic two-dimensional compressible turbulent velocity field. We show that the interplay between turbulent dynamics and population growth and saturation leads to quasi-localization and a remarkable reduction in the carrying capacity. The statistical properties of the population

Animal Biodiversity and Conservation, 2007 Increases or decreases in the size of populations over space and time are, arguably, the motivation for much of pure and applied ecological research. The fundamental model for the dynamics of any population is straightforward: the net change over time in

Housing and health outcomes: evidence on child morbidities from six Sub-Saharan African countries
BMC Pediatrics, 2023 Background The connection between healthy housing status and health is well established. The quality of housing plays a significant role in infectious and non-communicable as well as vector-borne diseases.
