Population Dynamics [PDF]

Nature Precedings, 2009
AbstractExplicit assumption that the use of natural resources promoting and sustaining growth is proportional to the number of people living on the planet at any given time leads to a model, which reproduces the population data remarkably well.

Stochastic gain in population dynamics

, 2004
We introduce an extension of the usual replicator dynamics to adaptive learning rates. We show that a population with a dynamic learning rate can gain an increased average payoff in transient phases and can also exploit external noise, leading the system

Coevolutionary Dynamics: From Finite to Infinite Populations [PDF]

, 2005
Traditionally, frequency dependent evolutionary dynamics is described by deterministic replicator dynamics assuming implicitly infinite population sizes.

Particle Statistics and Population Dynamics

, 2004
We study a master equation system modelling a population dynamics problem in a lattice. The problem is the calculation of the minimum size of a refuge that can protect a population from hostile external conditions, the so called critical patch size ...

Population Dynamics and Non-Hermitian Localization

, 1999
We review localization with non-Hermitian time evolution as applied to simple models of population biology with spatially varying growth profiles and convection.

Adaptive dynamics in logistic branching populations [PDF]

, 2007
We consider a trait-structured population subject to mutation, birth and competition of logistic type, where the number of coexisting types may fluctuate.

Population Dynamics and Their Components

, 2023
AbstractThe Mediterranean has an average annual population growth rate of around 1%, which is about the same as the world population growth rate. With a few rare exceptions, this growth is not principally fuelled by migration flows. However, it is closely linked to the demographic transition still underway in many Southern and Eastern Mediterranean ...

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 for stochastic processes.

Entropy production of cyclic population dynamics

, 2010
Entropy serves as a central observable in equilibrium thermodynamics. However, many biological and ecological systems operate far from thermal equilibrium. Here we show that entropy production can characterize the behavior of such nonequilibrium systems.

Evolutionary dynamics on any population structure

, 2016
Evolution occurs in populations of reproducing individuals. The structure of a biological population affects which traits evolve. Understanding evolutionary game dynamics in structured populations is difficult. Precise results have been absent for a long
