Controlling spatial interacting populations

International Journal of Computer Applications in Technology, 2011
Prey-predator models can exhibit various forms of pattern formation. Spatio-temporal dynamics of prey-predator systems are relevant for several ecological applications. Spatial synchrony is one manifestation among a broader array of space-time patterns.

The Spatial Dimension in Population Fluctuations

Science, 1997
Theoretical research into the dynamics of coupled populations has suggested a rich ensemble of spatial structures that are created and maintained either by external disturbances or self-reinforcing interactions among the populations. Long-term data of the Canadian lynx from eight Canadian provinces display large-scale spatial synchrony in population ...

Spatial Synchrony in Populations of Birds: Effects of Habitat, Population Trend, and Spatial Scale

Ecology, 2000
The degree of synchrony between populations is critical for their dynamics at large spatial scales. Population synchrony has been assessed for only a few species of vertebrates, most of them have largely fluctuating populations with multiannual cycles.

Modeling spatial aggregation of finite populations

Ecology, 2010
Accurate description of spatial distribution of species is essential for correctly modeling macroecological patterns and thus to infer mechanisms of species coexistence. The Poisson and negative binomial distribution (NBD) are most widely used to respectively model random and aggregated distributions of species in infinitely large areas.

Spatial heterogeneity and the persistence of populations

Oecologia, 1974
The hypothesis that dispersal in a heterogeneous environment can be an important factor in population stability is examined. It is shown that dispersal may increase the persistence time of a population by several orders of magnitude.
