Complex dynamics and phase synchronization in spatially extended ecological systems
Article Abstract:
The synchronization of complex population oscillations in model communities and natural systems has been studied. Each local patch in the proposed spatial model, maintains a three-level trophic system consisting of interacting predators, consumers and vegetation. Synchronization is often seen as detrimental to spatially structured populations, but phase synchronization results in complex chaotic travelling-wave structures, which may be vital for species persistence.

Seasonal dynamics of recurrent epidemics
Article Abstract:
A study was conducted to gain insights into the nonlinear dynamics of recurrent diseases through the analysis of the classical seasonally forced susceptible, infectious or recovered (SIR) epidemic model. In forced systems seasonal changes could prevent late-peaking diseases from spreading widely, thereby increasing population susceptibility and controlling the triggering and intensity of future epidemics.

The three-player solution
Article Abstract:
The two theories are highlighted to explain the insect, gypsy moth, outbreaks where the first argues that climatic factors set conditions for the outbreaks and the second argues that biotic interaction is largely responsible. The unpredictable insect-pest population is understood with the advent of a deceptively simple model combining field and laboratory data with earlier theories.
