This paper reports the occurrence of several chimera patter ns and the associated transitions among them in a network of coupled oscillators, which are con nected by a long range interaction that obeys a distance-dependent ...

In spatial ecology, dispersal among a set of spatially separated habitats, named as metapopulation, preserves the diversity and persistence by interconnecting the local populations. Understanding the effects of several ...

Research aimed at identifying indicators of persistent abrupt shifts in ecological communities, a.k.a regime shifts, has led to the development of a suite of early warning signals (EWSs). As these often perform inaccurately ...

Network structure or connectivity patterns are critical in determining collective dynamics among interacting species in ecosystems. Conventional research on species persistence in spatial populations has focused on ...

We define and study synchronisation in a linear array of nearest-neighbour coupled lasers. Our focus is on possible synchronisation types and the stability of their corresponding synchronisation manifolds with dependence ...

We study the effects of predation on the competition of prey populations for two resources in a chemostat. We investigate a variety of small food web compositions: the bi-trophic food web (two resources—two competing prey) ...

Anthropogenic global warming in this century can act as a leading factor for large scale species extinctions in the near future. Species in order to survive need to develop dispersal strategies depending upon their environmental ...

One of the most important issues in spatial ecology is to understand how spatial synchrony and dispersalinduced stability interact. In the existing studies it is shown that dispersion among identical patches results ...

Early warning signals (EWS) are statistical indicators that a rapid regime shift may be forthcoming. Their development has given ecologists hope of predicting rapid regime shifts before they occur. Accurate predictions, ...

There is a long history in ecology of using mathematical models to identify deterministic processes that may lead to dramatic population dynamic patterns like boom-and-bust outbreaks. Stochasticity is also well-known to ...
