Title: | Measuring Chaos from Spatial Information |
Authors: | Solé, Ricard V. CSIC ORCID ; Bascompte, Jordi CSIC ORCID | Issue Date: | Jul-1995 | Publisher: | Academic Press | Citation: | J. theor. Biol. (1995) 175, 139–147 | Abstract: | A new class of Lyapunov exponents are calculated from a simple numerical approach based on a spatially de_ned average of local divergence of trajectories[ This is a new way of identifying chaos in ecological data where\ because of its limited length and quality\ current techniques derived from the dynamical systems theory are not applicable[ In the examples presented\ only a very short time series "around 09 time steps# is necessary for obtaining a close estimate of the spatiotemporal Lyapunov exponent if the lattice size is high enough[ The method is applied to three previously studied coupled map lattice models and is shown to be a good measure for spatiotemporal chaos and an alternative way of estimating the underlying dimension[ | Publisher version (URL): | http://dx.doi.org/10.1006/jtbi.1995.0126 | URI: | http://hdl.handle.net/10261/44291 | DOI: | 10.1006/jtbi.1995.0126 |
