4 Aug 2004 | | Subject: | Chaotic Dynamics; Adaptation and Self-Organizing Systems; Populations and Evolution | nlin.CD nlin.AO q-bio.PE | | Abstract: | Coherence evolution of two food web models can be obtained under the stirring effect of chaotic advection. Each food web model sustains a three--level trophic system composed of interacting predators, consumers and vegetation. These populations compete for a common limiting resource in open flows with chaotic advection dynamics. Here we show that two species (the top--predators) of different colonies chaotically advected by a jet--like flow can synchronize their evolution even without migration interaction. The evolution is charaterized as a phase synchronization. The phase differences (determined through the Hilbert transform) of the variables representing those species show a coherent evolution. | | Source: | arXiv, nlin.CD/0408008 | | Services: | Forum | Review | PDF | Favorites | |
